摘要
城市公园绿地空间在提供生态效益和社会效益方面发挥着重要作用。城市化进程的迅速推进,导致社会阶层分化现象日益加剧,社会群体无法公平享有公共绿地资源,尤其是老年人群体。以北京市主城区133个街道的340个公园绿地为研究对象,改进公园绿地供给模型,基于供需关系等评价城市公园绿地供给公平性,提出公园绿地优化布局方案。结果表明:(1)改进后的公园绿地供给模型充分考虑了不同公园类型及公园质量。(2)研究区域内46.6%的公园绿地总供给无法满足老年群体需求,区域主要聚集在北京市二环至五环;相比游园、区域公园和市域公园,老年群体享有社区公园绿地供给的机会更多。(3)老年人享有的公园绿地供给未能达到社会正义的底线要求。在海淀街道、上地街道、大屯街道等区域新增公园绿地,提升望京公园、地坛公园等的公园质量是促进绿地公平性的有效手段。研究结果可为优化城市公园绿地空间的决策提供支持,为城市精细化管理提供参考。
Urban green space plays an important role in providing ecological and social benefits.The rapid advancement of urbanization has led to increasing social stratification and inequitable access to public green space resources for social groups,especially the elderly.For this reason,340 parks in 133 streets in the main urban area of Beijing are taken as the research objects,and the park green space supply model is improved to evaluate the fairness of urban park green space supply based on the relationship between supply and demand,etc.,and put forward the optimized layout plan of park green spaces.The results show that:(1)The improved park green space supply model fully takes into account different park types and park quality.(2)The total park green space supply in 46.6%of the study area fails to meet the demand of the elderly,clustered in the second to fifth ring road of Beijing;compared with the other three park green space types,the elderly have more opportunities to enjoy the supply of community parks and greenspaces.(3)The supply of parks and green spaces enjoyed by the elderly failure to meet the bottom-line requirements of social justice Adding new park green space in Haidian Street,Shangdi Street,and Datun Street and upgrading the park quality of Wangjing Park and Ditan Park are effective means to promote green space equity.The results of the study can provide support for decision-making on optimizing urban park green space and provide a reference for urban refinement management.
