多情景模拟下城市绿色基础设施网络优化研究
Research on the optimization of urban green infrastructure network under multi-scenario simulation:A case study of Hefei City
摘要
Abstract
To address the lack of dynamic response and insufficient multi-objective coordination in urban green infrastructure(GI)planning,this study takes rapidly urbanizing Hefei City as research object and de-velops a research framework of"multi-scenario simulation—network optimization—performance evaluation"to optimize the GI network.The PLUS model and MSPA method are used to simulate land use and GI net-work evolution under three scenarios for 2035:natural development,ecological protection and economic de-velopment.By integrating circuit theory with landscape connectivity analysis,the comprehensive resistance surface is constructed and the GI corridor is extracted.Ecological pinch points and obstacles are identified.A hierarchical optimization strategy for sources,corridors,and nodes is then proposed.The results indicate that the ecological protection scenario can effectively curb the loss of ecological land.After optimization,by adding 27 stepping stones,upgrading core corridors,and adding potential corridors,the α index,β index,and γ index of Hefei's GI network increased to 0.73,2.37 and 0.82,respectively,demonstrating significant improvements in network closure and connectivity.The proposed GI network optimization scheme is aligned with territorial spatial planning,provideing a scientific paradigm and practical reference for GI planning and ecological resilience improvement in high-density cities.关键词
