Indeed, the South contains 25% of water reserves of the country whom 10% are superficial water. The different hydrogeological studies show that the Zeuss-Koutine region is composed of several aquifer systems, which may be subdivided into two distinct levels;a superficial and a deep one. Such water resources show signs of localized over- exploitation which has a serious effect on the change of the hydrosystem characteristics in this region. Recently, Tunisia proves to be very interested in the contribution of new technology in particular Geographic Information System (GIS) to resolve the problem of water resources deficit in Tunisia essentially in semiarid southern part, in addition to the increased exploitation of groundwater resources, not renewable basically in last years. Hence, preserving water resources in the short and long term is a must. This fact might be achieved by the geographical information system (GIS). To respond to this object, detailed hydrological and hydrogeological studies are efficient, and a Geographic Relational Data Base Management System (RDBMS) by MERISE model was created in this study for organization of all these data in a structured way (method) and was easily exploitable under it. In addition, a lithostratigraphic correlation by the GIS is very important for understanding of the aquifer geometry and hydrodynamic interactions. The correlation among multi data shows a high degradation increasing from the South to the North (both quality and quantity of the Zeuss-Koutine groundwater). That is why another study of the water quality (salinity) and exploitation is considered crucial.展开更多

文摘The scarcity of shallow water, which is a delicate matter in southern Tunisia, is relatively compensated by groundwater resources. Indeed, the South contains 25% of water reserves of the country whom 10% are superficial water. The different hydrogeological studies show that the Zeuss-Koutine region is composed of several aquifer systems, which may be subdivided into two distinct levels;a superficial and a deep one. Such water resources show signs of localized over- exploitation which has a serious effect on the change of the hydrosystem characteristics in this region. Recently, Tunisia proves to be very interested in the contribution of new technology in particular Geographic Information System (GIS) to resolve the problem of water resources deficit in Tunisia essentially in semiarid southern part, in addition to the increased exploitation of groundwater resources, not renewable basically in last years. Hence, preserving water resources in the short and long term is a must. This fact might be achieved by the geographical information system (GIS). To respond to this object, detailed hydrological and hydrogeological studies are efficient, and a Geographic Relational Data Base Management System (RDBMS) by MERISE model was created in this study for organization of all these data in a structured way (method) and was easily exploitable under it. In addition, a lithostratigraphic correlation by the GIS is very important for understanding of the aquifer geometry and hydrodynamic interactions. The correlation among multi data shows a high degradation increasing from the South to the North (both quality and quantity of the Zeuss-Koutine groundwater). That is why another study of the water quality (salinity) and exploitation is considered crucial.

文摘The proton exchange membrane fuel cell(PEMFC)and the hydrogen hybrid power system are studied by the fuzzy-PID(FPID)controlmethod and the fuzzy-PID controlmethod by Artificial Bee Colony algorithm(ABCFPID),respectively.The results reveal that compared with the FPID control method,the temperature overshoot of the PEMFC stack under the ABC-FPID control method is decreased by 0.6%.Moreover,the circulating water flow rate within the full operating envelope(about 3 min)is reduced by 19.46 L,which means the ABC-FPID control method is more effective in regulating the stack temperature.Then,the ABC-FPID control method is proposed to study the hydrogen hybrid power system,and the system output power matching,operating characteristic curve of the fuel cell,state of charge(SOC)of the lithium battery,system efficiency and hydrogen demand are obtained.The results indicate that the maximum system efficiency reaches 46.3%,the average system efficiency is 33.8%,and the average hydrogen demand is 0.192 kg/s.Overall,the ABC-FPID control method can efficiently ensure the stability of the fuel cell’s output power,and actively prompt the lithium battery to fulfill the function of“peak shaving and valley filling”under variable load power conditions.

文摘Understanding the complex interactions between human activities and ecosystem functions is a prerequisite for achieving sustainable development.Since the implementation of the“Grain for Green”Project in 1999,ecosystem functions in China’s Loess Plateau have significantly improved.However,intensified human activities have also exacerbated the pressures on the region’s fragile ecological environment.This study investigates the spatiotemporal variations in the human activity intensity index(HAI)and net ecosystem benefits(NEB)from 2000 to 2020,using expert-based assessments and an enhanced cost-benefit evaluation framework.Results indicate that HAI increased by 16.7% and 16.6% at the grid and county levels,respectively.NEB exhibited pronounced spatial heterogeneity,with a total increase of USD 36.2 trillion at the grid scale.At the county level,the average NEB rose by 75%.The degree of trade-off was higher at the grid scale than at the county scale,while the synergistic areas initially expanded and then declined at both scales.Key areas for improvement and regions of lagging development were identified as priority zones for ecological management and spatial planning at both spatial resolutions.This study offers scientific insights and practical guidance for harmonizing ecological conservation with high-quality development in ecologically vulnerable regions.
文摘To address the severe challenges of PM_(2.5) and ozone co-control during the"14^(th) Five-Year Plan"period and to enhance the precision and intelligence level of air environment governance,it is imperative to build an efficient comprehensive management platform for regional air quality.In this paper,the specific practice in Zibo City,Shandong Province is as an example to systematically analyze the top-level design,technical implementation,and innovative application of a comprehensive management platform for regional air quality integrating"perception monitoring,data fusion,research judgment of early warnings,analysis of sources,collaborative dispatching,and evaluation assessment".Through the construction of an"sky-air-ground"integrated three-dimensional monitoring network,the platform integrates multi-source heterogeneous environmental data,and employs big data,cloud computing,artificial intelligence,CALPUFF/CMAQ,and other numerical model technologies to achieve comprehensive perception,precise prediction,intelligent source tracing,and closed-loop management of air pollution.The platform innovatively establishes a full-process closed-loop management mechanism of"data-early warning-disposition-evaluation",and achieves a fundamental transformation from passive response to active anticipation and from experience-based judgment to data driving in environmental supervision.The application results show that this platform significantly improves the scientific decision-making ability and collaborative execution efficiency of air pollution governance in Zibo City,providing a replicable and scalable comprehensive solution for similar industrial cities to achieve the continuous improvement of air quality.
文摘Purpose-Interface management is the process of managing communications,responsibilities and coordination of project parties,phases or physical entities which are dependent on one another.Interface management is a crucial part of managing any construction project-but particularly important for high-speed railway projects that often have several contractual parties and stakeholders,very long project timelines and huge upfront cost overlays.This paper discusses how various project interfaces were managed during the design and construction of the civil engineering infrastructure for the High Speed Two(HS2)project in the United Kingdom.Design/methodology/approach-The paper uses the case study methodology.Key interfaces on the HS2 project are grouped into various categories and the paper discusses how they were managed within the Area North Integrated Project Team(IPT)of the HS2 project made up of contractor Balfour Beatty VINCI(BBV),the Mott MacDonald SYSTRA Design Joint Venture(DJV)and client HS2 Ltd.3 different case studies drawn from across the IPT are used,each of them highlighting different interfaces and how these interfaces were managed.Findings-The paper shows how innovative technical designs and modern methods of construction were used to address some of the unique and peculiar challenges of designing a brand-new railway in the United Kingdom.Addressing the contrasting and often competing requirements of different stakeholders,coupled with challenging physical constraints of the very limited land available for the project and the use of a rarely used Act of Parliament in the delivery of the project required different approach to interface management.Collaboration and proactive stakeholder engagement are necessary for successful interface management on megaprojects.The authors posit that adopting an integrated approach to engineering and construction management is an essential ingredient for the successful delivery of high-speed railway projects.Originality/value-With many high-speed railway projects around the world coming up in the next few years,understanding the context and challenges for each country will help engineering and design managers adopt appropriate approaches for their projects.The lessons learned on the HS2 project are also transferable to other mega infrastructure projects with complex project interfaces.

文摘Tooth developmental anomalies are a group of disorders caused by unfavorable factors affecting the tooth development process,resulting in abnormalities in tooth number,structure,and morphology.These anomalies typically manifest during childhood,impairing dental function,maxillofacial development,and facial aesthetics,while also potentially impacting overall physical and mental health.The complex etiology and diverse clinical phenotypes of these anomalies pose significant challenges for prevention,early diagnosis,and treatment.As they usually emerge early in life,long-term management and multidisciplinary collaboration in dental care are essential.However,there is currently a lack of systematic clinical guidelines for the diagnosis and treatment of these conditions,adding to the difficulties in clinical practice.In response to this need,this expert consensus summarizes the classifications,etiology,typical clinical manifestations,and diagnostic criteria of tooth developmental anomalies based on current clinical evidence.It also provides prevention strategies and stage-specific clinical management recommendations to guide clinicians in diagnosis and treatment,promoting early intervention and standardized care for these anomalies.
文摘Objective:To investigate the application effect of intelligent empowerment standardized airway management process in patients receiving mechanical ventilation.Methods:A retrospective analysis was conducted on the clinical data of 79 EICU inpatients who underwent tracheal intubation and mechanical ventilation treatment at our hospital from January 2023 to May 2025.The patients were divided into a control group(conventional airway management process,n=40)and a study group(intelligent empowerment standardized airway management process,n=39)based on the intervention protocols they received.Oral health scores,dental plaque index,oral odor,serum inflammatory markers[C-reactive protein(CRP),procalcitonin(PCT)],clinical pulmonary infection score(CPIS),as well as the incidence of ventilator-associated pneumonia(VAP),duration of mechanical ventilation,and length of stay in the EICU were assessed before and after treatment.Results:The baseline values of all indicators were consistent between the two groups before intervention(p>0.05).After corresponding interventions,both groups showed significant improvements in Beck oral health scores,dental plaque index,and oral odor,with more pronounced improvements observed in the study group(p<0.05).After the intervention,the research group showed a significant decrease in serum CRP and PCT levels,as well as CPIS scores(p<0.05).In contrast,the control group experienced an increase in these three indicators to a certain extent(p<0.05).Moreover,the incidence of ventilator-associated pneumonia(VAP),duration of mechanical ventilation,and length of stay in the EICU were all lower in the research group compared to the control group,while the nurse’s compliance rate with the protocol was higher in the research group(p<0.05).Conclusion:The standardized airway management protocol empowered by intelligent technology can significantly improve nursing compliance,benefit oral health status,reduce the risk of pulmonary infection and systemic inflammation levels,and promote rapid patient recovery,demonstrating considerable potential for widespread adoption.
文摘Purpose-This study explores how managerial leadership and organizational innovation interact to enhance resilience and risk management in railway supply chains and how these capabilities contribute to sustained competitive advantage.It emphasizes the strategic importance of resilience in railway systems that face operational complexity,regulatory pressures and increasing exposure to systemic risks.Design/methodology/approach-A mixed-methods design was employed,integrating survey data from 186 railway organizations with six case studies involving railway operators,rolling stock manufacturers and supply chain partners across multiple regions.Constructs were measured using validated scales and hypothesized relationships were tested using Structural Equation Modeling(SEM).Case study interviews were analyzed thematically to provide contextual understanding of leadership practices and innovation strategies.Findings-The results confirm that transformational managerial leadership significantly predicts innovation adoption,which in turn strengthens resilience and risk management capabilities.Resilience emerged as a powerful driver of competitive advantage,reinforcing its role as a strategic capability rather than a reactive response to disruptions.Furthermore,innovation was shown to partially mediate the relationship between leadership and resilience,highlighting its function as the operational channel through which vision translates into capability.Originality/value-This study contributes to the literature by integrating the Resource-Based View(RBV)and Dynamic Capabilities(DC)framework into the context of railway supply chains.It is among the first to empirically validate the mediating role of innovation between leadership and resilience,offering both theoretical advancements and actionable strategies for building resilient and competitive railway systems.

文摘Climate change profoundly influences sulfur(S)nutrition,which plays a crucial role in plant growth,development,and responses to diseases.Climate-induced stress may impair plant growth,photosynthesis,pollen development,and reproduction.For instance,under high temperature stress,plant photosynthetic efficiency is reduced due to the overproduction of reactive oxygen species,denaturation of heat shock proteins,and alterations in various enzyme activities.Unlike drought stress,plants have developed only a few mechanisms to mitigate heat stress.Utilization of S is one of the efficient strategies to enhance plant tolerance against biotic and abiotic stresses.Plant-derived S-containing secondary metabolites play a vital role in plant-pest and plant-disease interactions in various plants.However,little is known about the roles of S and its management strategies in response to disease attack in wheat and barley under climate change.A deeper understanding of S-based strategies could contribute to sustaining plant health and productivity,thereby supporting global wheat and barley yields in the face of increasing climate change challenges.This review therefore focuses on the roles of S and associated management strategies utilized to support plant growth,development,and reproduction and enhance disease resistance and tolerance to abiotic stresses in wheat and barley under climate change.
文摘Chronic pain represents a significant global health challenge,and the limitations of conventional analgesics have urged a search for alternative therapeutic strategies.Cannabinoids derived from Cannabis sativa have emerged as prominent candidates.While psychotropic cannabinoids are known for their analgesic effects,their psychoactive properties often limit their clinical utility.Consequently,interest has shifted towards non-psychotropic cannabinoids that offer potential pain relief without inducing cognitive or euphoric effects.This comprehensive review investigates the pain-modulating mechanisms of cannabinoids,encompassing interactions with the endocannabinoid system and other non-traditional pathways,and summarizes the existing preclinical and clinical evidence supporting their use in various pain states.Furthermore,it discusses the therapeutic potential,clinical considerations,significant challenges,and the need for product standardization.This review also aims to evaluate the role and prospects of non-psychotropic cannabinoids as a therapeutic option for pain management.
文摘Springs are vital freshwater sources for rural communities,yet they are increasingly threatened by nutrient enrichment,microbial contamination,and declining ecological integrity.This study assessed the water quality of Sumber Suko Spring in East Java,Indonesia,through an integrated ecological approach combining physicochemical,microbiological,biological,and hydrological parameters across wet and dry seasons.Physicochemical results showed stable temperature(24.1–26.7°C),near-neutral pH(6.4–6.9),and adequate dissolved oxygen(6.2–7.4 mg/L).However,nitrate concentrations were elevated(39.37–48.16 mg/L),exceeding natural background levels and indicating agricultural leaching,while phosphate values ranged between 0.12–0.21 mg/L.Microbial analysis revealed high total coliform counts(24 CFU/100mL),far above WHO standards,although E.coli was not detected.Plankton analysis identified 10 genera,with Microcystis aeruginosa dominating,particularly in the dry season,signaling risks of eutrophication.Shannon-Wiener diversity indices(H’)ranged from 1.25 to 1.67,with evenness values between 0.43 and 0.56,reflecting low-to-moderate community stability.Hydrological measurements showed seasonal discharge fluctuations from 14.6 L/s in the wet season to 7.8 L/s in the dry season,strongly correlated with rainfall.Overall,the integration of nutrient enrichment,coliform contamination,and cyanobacterial dominance indicates that Sumber Suko Spring is under ecological stress and does not meet drinking water standards without treatment.The findings highlight the urgent need for source protection,disinfection,and continuous monitoring within a water safety plan framework.This study provides evidence-based insights to support local policy alignment with WHO guidelines and emphasizes the importance of community participation in sustaining spring ecosystems for long-term water security.
文摘The post-hoc analysis of the PERSEO registry by Minardi,et al.[1]offers critical insights into antithrombotic management for elderly patients(≥80 years)on oral anticoagulation undergoing percutaneous coronary intervention.While the authors effectively demonstrate the vulnerability of this population,characterized by substantial comorbidity burden and markedly elevated rates of mortality,ischemic events,and bleeding at one year compared with younger cohorts,their findings raise important questions about contemporary practice patterns and their alignment with evidence-based guidelines.
文摘Water resources health diagnosis is increasingly recognized as a critical tool.It should not only guide the preservation of water volume,quality,and ecological integrity but also assess the viability of carbon-neutral development pathways.But current research tends to consider water health assessment and carbon-neutrality planning as separate endeavors,which results in imprecise boundaries,disjointed metrics,and a weak linkage between diagnostic outcomes and testable management actions.This review brings together indicator systems,diagnostic systems,and environmental management systems architectures that make it possible to have integrated water-carbon governance.We define fundamental concepts and delimiting decisions followed by the examination of indicator designs across the hydrological regime,water quality,ecological integrity,service performance,resilience,and carbon-related measures,including intensity of energy/emissions,emissions caused by the watershed process of wastewater treatment,as well as the potential sink of the watershed.We compare diagnostic methods,such as composite indices and multi-criteria decision analysis,data-driven early-warning models,process-based and integrated simulations,as well as uncertainty-aware robustness models.Here,based on this synthesis,we suggest an environmental management systems(EMS)-based pathway,which connects the setting of the baseline,the diagnosis,the design of the intervention portfolio,and the measurement-reporting-verification into the closed-loop adaptive cycle.Digital enablement,comprising Internet of Things(IoT)monitoring,remote sensing,data fusion,optimization,and digital twins,is considered a viable way of scaling implementation,subject to interoperability,validation,and model governance.Among the major gaps,there are causal attribution to outcomes,cross-scale coupling of facility emissions and basin health,propagation of uncertainty in a coupled model,and credible Measurement,Reporting,and Verification(MRV)of non-CO_(2) gases and nature-based removals.The review gives a roadmap to normalize core metrics and fast-deployable systems to protect the health of the water resources and give verifiable progress towards carbon neutrality.

文摘Bofedales,high-altitude Andean peatlands,are critical to the sustainability of mountain ecosystems and the livelihoods of pastoral communities.This study presents findings from a transdisciplinary research project focused on two bofedal systems,Sorapata and Aychuta,within Bolivia's Sajama National Park.Using vegetation assessments from 2012 to 2018,we identified a marked decline in cushion-forming species(Distichia muscoides and Oxychloe andina),and a clear shift in community composition,indicating a trend toward desiccation.Land cover analyses from 2014 to 2021 revealed a contraction of dense bofedales and an expansion of dry bofedales and bare soil,indicating sustained degradation.These dynamics manifested differently across sites.In Sorapata,degradation was dominant,although localized irrigation practices implemented in 2018 facilitated partial recovery in one sector.These varied trajectories reveal simultaneous processes of decline and recovery.In contrast,Aychuta maintained relatively stable cushion-dominant vegetation,though vegetation surveys and land cover analyses both revealed early shifts in composition and cover associated with climate change.Together,these patterns reveal simultaneous processes of decline,stability,and recovery.Ecological findings align with interviews with indigenous herders,who attribute degradation to reduced precipitation,rising temperatures,and seismic activity,while emphasizing the role of water management in bofedal restoration.Our results highlight the vulnerability of bofedales to climatic and environmental stressors,emphasizing the importance of integrated water management strategies in their conservation under changing climatic conditions.We advocate for transdisciplinary approaches that combine ecological research,integrate multi-year vegetation surveys,remote sensing,and traditional ecological knowledge to enhance our understanding and conservation of these critical socioecological systems.
文摘BACKGROUND:Airway management is a core competence in emergency medicine.International registries have described indications,techniques,and outcomes of endotracheal intubation,yet contemporary data from German emergency departments(EDs) are scarce.We conducted a multicenter prospective registry study in Thuringia,to characterize indications,techniques,success rates,and complications of ED intubations.METHODS:From February 2023 to January 2024,six Thuringian EDs participated in a prospective observational registry(www.airwayregistry.eu).All consecutive intubations were documented anonymously using a standardized digital form.Demographics,indications,methods,equipment,operator characteristics,first pass success(FPS),overall success,and complications were captured.Descriptive statistics were used.RESULTS:We analyzed 117 intubations(63.2% male;mean age 68.4 years,range 2–98 years).FPS was 88.9%(104/117),second pass success was 4.3% and third pass success was 6.8%;overall success was 100%.Rapid sequence intubation(RSI) was used in 77.8% of intubations and delayed sequence intubation(DSI) in 21.4%;10.3% were performed without medication.Direct laryngoscopy(DL) was used in 65.0% and videolaryngoscopy(VL) in 34.2%.FPS was higher with VL than DL(92.5% vs.88.2%).The most common indications were cardiopulmonary resuscitation(14.5%) and stroke/ischemia(13.7%);intracranial hemorrhage accounted for 13.7%.Complications occurred in 39% of cases,most frequently hypotension(23.9%) and catecholamine requirement(12.0%).A difficult airway was anticipated in 30.8%.CONCLUSION:In this multicenter snapshot from German EDs,overall intubation success was high but complications—especially peri-intubation hypotension—were common.VL yielded higher FPS yet was used less frequently than DL.Standardized protocols,hemodynamic optimization,and broader VL adoption may improve safety and performance.
文摘The built environment and construction industry are another significant source of carbon emissions to the environment in the world,through the production of materials,construction activities,and the energy consumed during the lifecycle of an asset.These emissions are difficult to manage effectively because the data are not consolidated,the operating conditions are dynamic,and the traditional assessment tools are not able to support continuous and data-driven decisions.The new technologies,especially Digital Twins(DT)and artificial intelligence(AI),have some potential solutions,which will combine the lifecycle data and provide a predictive,adaptive carbon management in the building and urban systems.The given paper is a systematic review of the integration of DT and AI(DT–AI)into carbon management in operational construction and urban planning.Structured database searches and filters on the basis of DT-facilitated carbon monitoring,prediction,optimization,and operational control were used to identify peer-reviewed studies that were published within the last few years and filtered through to gather them.Three main functions of DT–AI systems are outlined in the review:predicting carbon emissions on the basis of data-driven models,optimizing low-carbon design and planning with multi-objective approaches,and providing intelligent control of the energy systems.Some of the major issues are data interoperability,model validation,and a lack of evidence of large-scale deployment.This study combines integrated DT–AI models and their contribution to lifecycle carbon management,unlike the previous reviews of either DT or AI alone.The paper ends with a conclusion and recommendations to create scalable,validated DT–AI solutions to accomplish carbon-neutral built environments.

文摘Cellulose frameworks have emerged as promising materials for light management due to their exceptional light-scattering capabilities and sustainable nature.Conventional biomass-derived cellulose frameworks face a fundamental trade-off between haze and transparency,coupled with impractical thicknesses(≥1 mm).Inspired by squid’s skin-peeling mechanism,this work develops a peroxyformic acid(HCOOOH)-enabled precision peeling strategy to isolate intact 10-μm-thick bamboo green(BG)frameworks—100×thinner than wood-based counterparts while achieving an unprecedented optical performance(88%haze with 80%transparency).This performance surpasses delignified biomass(transparency<40%at 1 mm)and matches engineered cellulose composites,yet requires no energy-intensive nanofibrillation.The preserved native cellulose I crystalline structure(64.76%crystallinity)and wax-coated uniaxial fibril alignment(Hermans factor:0.23)contribute to high mechanical strength(903 MPa modulus)and broadband light scattering.As a light-management layer in polycrystalline silicon solar cells,the BG framework boosts photoelectric conversion efficiency by 0.41%absolute(18.74%→19.15%),outperforming synthetic anti-reflective coatings.The work establishes a scalable,waste-to-wealth route for optical-grade cellulose materials in next-generation optoelectronics.
文摘Objective:To explore the intervention effect of comprehensive perioperative blood glucose management on patients with diabetes complicated with cataract surgery.Method:A total of 68 patients in our hospital from July 2024 to July 2025 were selected and randomly divided into the experimental group and the control group,with 34 cases in each group.The control group received routine blood glucose management,while the experimental group,on this basis,implemented individualized intervention 3 days before the operation,real-time regulation during the operation,dynamic management 7 days after the operation,and self-management training.Result:The blood glucose control in the experimental group was more stable 7 days after the operation.The total incidence of complications(2.9%)was significantly lower than that in the control group(38.2%),and the average hospital stay(5.1±1.0 days)was shorter than that in the control group(7.3±1.4 days).One week after the operation,the proportions of uncorrected visual acuity and visual acuity≥0.6(67.6%)were both better than those of the control group(p<0.001).Conclusion:The whole-course management of perioperative blood glucose can enhance the stability of blood glucose control,reduce the risk of complications,shorten the length of hospital stay,promote visual recovery,and has high clinical promotion value.

文摘Understanding the scale-dependent dynamics of ecosystem services(ESs)and their socio-ecological drivers is essential for sustainable development.While many studies rely on static or single-scale approaches,this research employs an integrated multi-temporal(2000–2020)and multi-scale(grid,county,and landscape levels)framework to investigate China’s Central Asian frontier,a representative dryland region.We quantified six ESs:habitat quality(HQ),net primary productivity(NPP),carbon sequestration(CS),water yield(WY),soil conservation(SC),and grain production(GP).Furthermore,we explored their interrelationships and identified the drivers influencing these services across different spatial scales.Our results revealed divergent ES trajectories:the declining HQ(−0.03 a^(−1)),NPP(−0.43 t km^(−2)a^(−1)),and SC(−3.41 t ha a^(−1))contrasted with rising WY(+2.33 mm a^(−1)),GP(+0.06 t km^(−2)a^(−1)),and CS(+0.02 t km^(−2)a^(−1)).The ES relationships were predominantly synergistic,while HQ–WY exhibited a trade-off(grid:−0.03;county:−0.02;landscape:−0.03)at temporal dimension but a synergistic relationship(grid:0.45;county:0.92;landscape:0.92)at spatial dimension.As spatial scale increased,SC–CS shifted from synergy(grid:0.001)to trade-off(county:−0.01;landscape:−0.005)in the temporal dimension,while all trade-off relationships in the spatial dimension were transformed into synergies.Key drivers of ES relationships varied with spatial scale:fraction vegetation coverage(FVC)and leaf area index(LAI)at the grid scale,annual precipitation(MAP)and soil moisture(SMA)at the county scale,and population density(POP),gross domestic product(GDP),and silt content(Silt)at the landscape scale.Based on the multi-scale findings,the study divides northern Xinjiang into Grain Priority Region,Ecological Priority Region,and Desert Containment Region,and proposes tailored management recommendations,offering a flexible framework for balancing ecological and socioeconomic needs.
