We discuss why hydrocarbon exploration has so far failed in the South Yellow Sea, and put forward alternative future exploration plans. The results show that there are thick Cenozoic strata over Jurassic-Cretaceous continental strata in the southern basin of the South Yellow Sea, contrasted with thick Mid-Paleozoic marine strata preserved in the middle uplift area. In the mid-southern South Yellow Sea, airborne Bouguer gravity anomalies are fragmentized with scattered local anomalies. Many tensile normal faults and minor fault blocks occur in the Cenozoic strata. In contrast, reverse faults and nappe structures are found in pre-Cenozoic strata. The essential reasons for the lack of a breakthrough in hydrocarbon exploration are the complexity of geological structures, hydrocarbon accumulation environments, seismic-geologic conditions, and the difficulty of interpreting and understanding these features, rather than an imbalance of exploration framework. Hydrocarbon exploration should be targeted at Mid-Cenozoic continental strata, especially of Paleogene age, in the middle to southern parts of the South Yellow Sea. Special attention should be paid to the favorable structural belts SYI1, SYI2, SYI3 and SYI4 in the southern basin of the South Yellow Sea, where detailed seismic exploration or drilling should be carried out. Attention should also be given to Mid-Paleozoic marine strata in the middle uplift area of the South Yellow Sea. Key strategies that could lead to a hydrocarbon exploration breakthrough are improving exploration resolution, conducting detailed studies of fine structures, and accurately locating minor structures.展开更多

文摘Current research on the dynamics and vibrations of geared rotor systems primarily focuses on deterministic models.However,uncertainties inevitably exist in the gear system,which cause uncertainties in system parameters and subsequently influence the accurate evaluation of system dynamic behavior.In this study,a dynamic model of a geared rotor system with mixed parameters and model uncertainties is proposed.Initially,the dynamic model of the geared rotor-bearing system with deterministic parameters is established using a finite element method.Subsequently,a nonparametric method is introduced to model the hybrid uncertainties in the dynamic model.Deviation coefficients and dispersion parameters are used to reflect the levels of parameter and model uncertainty.For example,the study evaluates the effects of uncertain bearing and mesh stiffness on the vibration responses of a geared rotor system.The results demonstrate that the influence of uncertainty varies among different model types.Model uncertainties have a more significant than parametric uncertainties,whereas hybrid uncertainties increase the nonlinearities and complexities of the system’s dynamic responses.These findings provide valuable insights into understanding the dynamic behavior of geared system with hybrid uncertainties.

文摘With the ongoing increase in population and rapid pace of economic development,the pressure on natural resources and the eco-environment intensifies.There is an urgent need to coordinate multiple land functions and reevaluate land use comprehensively[1].Incorporating the theories of ecology into traditional land science and land use management is a vital step forward.Land ecology,an important sub-discipline of land science,serves as an interdisciplinary field that integrates land science and ecology,often aligned with land sociology and land economics.

文摘A mechanistic understanding and modeling of the coupled human and natural systems(CHANS)are frontier of geographical sciences and essential for promoting regional sustainability.Modeling regional CHANS in the Yellow River Basin(YRB)featuring high water stress,intense human interference,and a fragile ecosystem has always been a complex challenge.Here,we propose a conceptual modeling framework to capture key human-natural components and their interactions,focusing on human-water dynamics.The modeling framework encompasses five human(Population,Economy,Energy,Food,and Water Demand)and five natural sectors(Water Supply,Sediment,Land,Carbon,and Climate)that can be either fully interactive or standalone.The modeling framework,implemented using the system dynamics(SD)approach,can well reproduce the basin's historical evolution in human-natural processes and predict future dynamics under various scenarios.The flexibility,adaptability,and potential for integration with diverse methods position the framework as an instructive tool for guiding regional CHANS modeling.Our insights highlight pathways to advance regional CHANS modeling and its application to address regional sustainability challenges.

文摘自然对人类的贡献(nature’s contributions to people,NCP)是指大自然对人类生活质量的一切积极贡献和消极影响,分为10个调节型NCP、4个物质型NCP和4个非物质型NCP.但目前这些NCP的全球时空分布及其相互作用规律尚不清楚,直接制约了加强自然界多种有益贡献的生态系统管理实践.本研究构建基于指标体系的评价方法,结合生态系统演变、气候变化与人类活动全球尺度多源空间数据集,在全球范围内对1990~2018年所有18个NCPs进行空间制图,在15,204个流域单元上识别主导了NCP组合,并基于NCPs时空特征识别了全球景观变化的功能权衡关系和景观多功能性.结果表明,全球大部分NCPs的高值仅在局地出现.1992~2018年,6个调节型NCP、3个物质型NCP和2个非物质型NCP下降.29种调节型和物质型NCP组合(总共有54种组合)的主导流域占全球76%的陆地面积,而无NCP主导的流域占全球陆地面积的22%.NCPs变化的协同关系比权衡关系更为常见,但调节型和物质型NCP之间的关系普遍处于权衡状态.过渡气候地区的NCP相对少,并具有强烈的权衡关系;而低纬度地区NCPs之间的高度协同关系可能受到未来气候变化的影响.研究结果提供了对全球NCP空间变化规律的总体认知,可用于科学支撑区域景观功能的关系调控和景观多功能性提升,以增强全球人类福祉.

文摘The novel coronavirus disease,named COVID-19,emerged in China in December 2019[1].In the early phases of the outbreak in Wuhan City,timely and effective control measures to prevent COVID-19 spread were delayed for several reasons,including lack of knowledge and vigilance regarding the new disease,insufficient or inefficient detection tools.However,the adoption by Chinese authorities of a systematic approach to the disease has resulted in the number of recoveries per day,since February 18th,2020,exceeding the number of newly confirmed cases,and the cumulative number of patients cured exceeded the remaining confirmed cases on February 28th,2020(http://www.nhc.gov.cn/xcs/yqtb/list_gzbd).

文摘Sustainable communities,while not explicitly defined universally,are now essential tools used by many countries to explore ways of enhancing regional sustainability,especially in China.1 To reduce the burden on the environment resulting from economic growth and to examine effective social governance models,China launched the construction of the Comprehensive Experimental Community for Social Development in 1986,since renamed the China National Sustainable Community(NSC)in 1997.2 Generally,NSCs are regions approved by the central government of China for exploring comprehensive solutions to various sustainable development challenges in the context of their development potential and to provide lessons for other regions,and they could be established in different administrative units such as cities or towns.1,2 It is estimated that more than 180 NSCs have been established in China.1 Although previous studies showed that NSCs have a significant role in improving the sustainability of the region itself,1 it remains unclear what impact NSCs have on the sustainability over a broader regional area,such as at the provincial scale.

文摘Unraveling the complexity of the 17 inter acting sustainable development goals(SDGs)is crucial for their achievement.Empirically revealing the dimensions of the SDGs helps generalize the dominant features of SDGs and better understand their drivers.Here,using a database of 166 countries'progress toward achieving each individual SDG,we found that about 70%of the variability of national SDG performance can be captured by three dimensions:socioeconomic development at the expense of resource and climate,the environment,and development at the expense of equality.Moreover,these dimensions are mainly affected by the economy,as gross domestic product(GDP)per capita increases,the first dimension increases monotonically,the environment dimension decreases and then increases,and the inequality dimension increases and then decreases.Our findings indicate a dim prospect of eventually achieving all SDGs because of the conflicts between economic growth and resource and cdimate goals under the current development paradigm,highlighting the importance of sustainable transformation.

文摘Sustaining or enhancing nature's contributions to people(NCPs)requires a comprehensive understanding of both nature's contributions and people's needs.However,the 2 aspects for water-related NCPs are spatially mismatched.We introduced an assessment framework for water-related NCPs from a spatial flow perspective,considering the local nature's contributions assessed using the In VEST(Integrated Valuation of Ecosystem Services and Tradeoffs)model,as well as people's needs in the downstream assessed via a distance decay method.We assessed 3 water-related NCPs'spatial distribution and correlation on the Loess Plateau from 2000 to 2020,where a large-scale ecological restoration was implemented that may affect downstream people.The results showed that NCP6(downstream needs from water yield)showed no increasing trend in the majority watersheds over the past 20 years,in contrast to NCP7(downstream needs from water purification)and NCP8(downstream needs from soil conservation).There are spatial synergies among NCP6,NCP7,and NCP8.From 2000 to 2020,the spatial synergy between NCP7 and NCP8 increased while decreased between other NCPs.The temporal dynamics of NCP6 and NCP8 showed a trade-off,while NCP6 and NCP7 showed a synergy.NCP7 and NCP8,in turn,showed a transition from synergy to trade-off.Guided by nature's contributions and people's needs,we proposed 3 ecological measures:thinning and intermediate cutting measures,control nonpoint source pollution,and soil and water conservation projects to promote ecological restoration.This assessment can offer multifunctional guidance for planning ecological conservation and restoration in the upstream based on people's needs in the downstream.

文摘Under the United Nations Decade on Ecosystem Restoration(2021 to 2030),a geographic context-specific issue emerged that how local people would like to support ecological restoration programs.Regarding previous studies,which often identified the key variables at a fixed scale,we formulated the scientific question as follows:how do landscape-level variables influence the impact of individual-level characteristics on residents'willingness to support ecological restoration?Based on a survey of 2,753 households that experienced ecological restoration programs in China's dryland and 4 landscape-level variables,namely,normalized difference vegetation index,land surface temperature,relative humidity,and precipitation,we quantitatively measured the geographic context-specific impacts on residents'willingness to support ecological restoration by multilevel linear models.
