Great Lakes Regions(GLRs)in China often confront landscape fragmentation,wetland degradation,and ecological resilience(ER)losses owing to extensive and intensive urbanization.In GLRs,however,the ER responses to urbanization remain unclear.This study explored the spatiotemporal evolution of ER and urbanization in five GLRs in China to analyze the ER dynamic patterns along center−lakeside−periphery gradient.The Spatial Durbin Model(SDM)and Panel Threshold Model(PTM)were combined to reveal the spillover and threshold effects of urbanization in five GLRs.The results indicate that the ER in five GLRs declined with a rate of 21%from 2000 to 2020.There was a clear“center-periphery”contraction trend with low ER areas primarily spreading to human activity-concentrated regions such as lakesides,riversides,and road networks.Driven by economic and land urbanization,the average urbanization level increased from 0.06 to 0.13,where lakesides,riversides,and road networks were key areas undergoing expansion.The urbanization showed a noticeable negative spatial spillover effect on ER.Away from central lakes,the negative impacts on ER exhibited a two-phase decrease with the threshold of 81 km.This study contributes to the understanding of human-environment interactions by examining the ecological resilience response process of GLRs under the impact of urbanization.Based on a multidimensional“center−lakeside−periphery”analytical model,this study provides a strategic framework for ecological construction in GLRs in China,promoting sustainable development and adaptive capacity in vulnerable areas. 展开更多

Rapid urbanization and global warming cause a sharp increase of frequency and intensity of stormwater disaster. Urban design, depending on the methodology of urban form and the creation of the spatial environment to promote stormwater resilience, has broken through the traditional design mode and become an efficient path leading to addressing urban stormwater disaster. Firstly, this paper discusses the concept and connotation of stormwater resilient urban design based on the resilient city theory in order to set up the theoretical framework of the design method. Then combining with the specific cases and focusing on four key problems of urban design, the practical urban design methods in favor of stormwater resilience are analyzed, including the optimization of land use, the organization of urban structure, the creation of multi-functional space, and the integration of urban systems. In the end, the paper further analyzes the challenges in practical application. Stormwater resilient urban design expands the boundary of traditional urban design and provides a new choice for performance-based e co-city design. 展开更多

The morphology of urban areas plays a crucial role in determining solar potential,which directly affects photovoltaic capacity and the achievement of net-zero outcomes.This study focuses on the City of Melbourne to investigate the utilization of solar energy across different urban densities and proposes optimized morphologies.The analysis encompasses blocks with diverse population densities,examining medium and high-density areas.By utilizing a multi-objective genetic optimization approach,the urban morphology of these blocks is refined.The findings indicate that low-density blocks exhibit photovoltaic potential ranging from 1 to 6.6 times their total energy consumption.Medium and high-density blocks achieve photovoltaic potential levels approximately equivalent to 40%-85%of their overall energy consumption.Moreover,significant variations in photovoltaic potential are observed among different urban forms within medium and high-density blocks.An“elevated corners with central valley”prototype is proposed as an effective approach,enhancing the overall photovoltaic potential by approximately 14%.This study introduces novel analytical concepts,shedding light on the intricate relationship between urban morphologies and photovoltaic potential. 展开更多

As a showcase for public well-being and urban identity, a better street should carry not only the constantly flowing traffic stream, but also diversified lifestyles and various streetscapes. Beijing is the capital of China, one of its ancient capitals, and a tier 1 international metropolis, both its street connotation and functions are extremely complex. Along with new requirements proposed in the Beijing City Master Plan(2016 – 2035) for controlling construction land, strengthening urban identity, and improving urban governance, the Urban Design Guidelines for Beijing Street Regeneration and Governance(the Guidelines) is not only an important breakthrough point for promoting urban transformation to sustainable urban regeneration and governance, but also the foundation of optimizing capital city construction and building a world-class, harmonious, and livable capital city. Taking full consideration of value orientation, technical methods, system design, and governance transformation, the Guidelines adopts five measures, including identity enhancement, coordinated design, enhancing cultural and aesthetic quality, building platforms, and managing 'stubborn diseases' – problems which have plagued people for many years and have been intensifying with years to pass, to comprehensively improve the street design and governance, in the hope of making it a real typical space that represents the image and cultural charm of the capital city. 展开更多

Urban public spaces are pivotal to the welfare and prosperity of modern cities.Recognizing their importance,this research addresses the critical gap in understanding and enhancing the qualities of these spaces through advanced analytics,focusing on Tehran’s main traditional market,the Bazaar.A novel methodological framework combining Social Network Analysis(SNA),and Strengths,Weaknesses,Opportunities,and Threats(SWOT)analysis,supported by location-based social media reviews,was employed.This innovative approach assessed the Bazaar’s comfort,vitality,and safety,analyzing real-time public interactions and perceptions through social media data.The findings highlighted the Bazaar’s central role in Tehran’s urban landscape and identified the need for strategic design interventions.These interventions aimed to improve walkability,comfort,safety,and diversity,and have been successfully implemented,significantly enhancing the Bazaar’s quality and usability.This study not only advances urban studies and planning by providing a model for urban public space analysis but also underscores the value of social media data in urban analytics.The successful revitalization of Tehran’s Bazaar sets a precedent for enriching urban experiences and boosting city vitality through similar interventions in other urban spaces. 展开更多

Polycentric urban development is promoted as a planning strategy to make cities and regions more efficient and sustainable.This article reviews the emerging literature on polycentric development in China.We find that Chinese urban regions are still largely monocentric,with emerging polycentric urban centers.There exists a geographical mismatch between urban centers identified by different metrics and composite indicators.The mechanism of polycentric urban development in China differs across cities and geographical scales,and the primary triggers include economic,institutional,and transportation factors,with a significant role of the state.Polycentric development has gained currency in planning policy in China,and these policies have contributed to polycentric urban development in well-developed regions.Furthermore,the Corona Virus Disease 2019(COVID-19)pandemic promoted suburbanization and limited people’s mobility,and polycentricity in the post-pandemic era is worthy of further investigation.This review calls for efforts for multiscale,multi-dimensional,and multi-mechanism understanding of polycentric development toward more powerful theoretical and policy contributions. 展开更多

Understanding the complex mechanisms underlying agricultural space urbanization is essential for sustainable land management.This study identified the spatiotemporal characteristics of the agricultural space urbanization from 2000 to 2020 in China’s Yangtze River Economic Belt(YREB)using a kilometer-grid-based approach.By employing the partial least squares structural equation modeling method,the intricate drivers of agricultural space urbanization were investigated.The results revealed that from 2000 to 2020,agricultural space urbanization in the YREB covered an area of 28,198 km^(2),accounting for 84.5%of the total increase in urban space.The partial least squares structural equation modeling analysis revealed regional variations in agricultural space urbanization dynamics.In the western YREB,where urbanization is in its initial stage,natural conditions play a weak and indirect role,whereas policy incentives and socioeconomic growth are equally significant in driving agricultural space urbanization.In the eastern YREB,where urbanization is more saturated,the agricultural space urbanization is less constrained by natural factors,showing a high synergy with socioeconomic development.Conversely,in the central Yangtze River Economic Belt,policy influences surpass socioeconomic factors,whereas unfavorable natural conditions and agricultural development act as key drivers of agricultural space urbanization.This study suggests that enhancing agricultural space urbanization quality requires strengthening region-specific policies,providing targeted support for remote areas,rebalancing policy orientation in rapidly urbanizing regions,and establishing a comprehensive evaluation system to ensure policy rationality. 展开更多
