摘要
公园绿地是实现城市可持续发展的重要保障,在上海市全面推进“15分钟社区生活圈”建设的背景下,评估公园绿地可达性对考核其空间布局的合理性及社区服务效率有重要意义。以上海市为研究区,基于多源数据和百度地图开发平台,运用多出行模式两步移动搜索法探究公园绿地的空间分布与可达性差异。研究发现:(1)上海市公园绿地分布存在城郊供需差异,城区公园绿地提供的服务优于郊区;(2)黄浦区、闵行区和奉贤区在公园绿地步行可达性和服务能力方面存在显著差异,黄浦区公园绿地的短时可达性好且服务能力强;(3)多出行模式下公园绿地可达性自城区向郊区升高,黄浦区的可达性极差小,人均绿地面积小,但公园绿地建设较完善;闵行区和奉贤区的可达性极差大,人均绿地面积大,但公园绿地建设有待完善。
Urban green spaces are crucial for achieving sustainable urban development.In the context of Shanghai’s comprehensive promotion of the“15-Minute Community Life Circle,”evaluating the accessibility of urban green spaces is essential for examining the rationality of their spatial distribution and the efficiency of community services.Based on multi-source data and the Baidu Map Development Platform,this study takes Shanghai as the study area,utilizing the Multi-mode Two-step Floating Catchment Area Method to explore the spatial distribution and accessibility disparities of urban green spaces.The results show that:(1)There is a discrepancy in the supply and demand of urban green spaces between urban and suburban areas,with urban parks providing better services than suburban ones;(2)Significant differences exist in the walking accessibility and service capacity of parks in Huangpu,Minhang,and Fengxian districts,with Huangpu having superior short-term accessibility and strong service capacity;(3)Under multiple travel modes,the accessibility of urban green spaces increases from the city center to the suburbs.Huangpu has a small accessibility gap and limited green space per capita,but well-developed green space infrastructure,whereas Minhang and Fengxian exhibit larger accessibility gaps,with more green space per capita but less developed green space infrastructure.
