摘　　要：[目的]探究居住区绿地对城市绿地供需匹配的影响,为提升城市绿地均衡性、改善居民福祉提供科学依据。[方法]以成都市武侯区街道为基本单元,在是否考虑居住区绿地两种情况下对城市绿地均衡性进行分析;运用生态系统服务量化方法综合对比成都市绿地空间供需分布现状,通过区位熵探索各街道生态系统服务供需关系,判断居住区绿地对城市绿地供需分布的贡献。[结果]成都市绿地空间供需分布不均匀;在考虑居住区绿地情况下,城市绿地分布全域均衡性提升了68.1%;局部均衡性分析中的不均衡单元减少。[结论]考虑居住区绿地后,城市绿地供需分布均衡程度得到改善。研究结果为优化城市绿地结构布局提供了新思路:保护现有公园绿地、优化居住区和公园绿地布局,以及优化城市绿地质量。[Objective]The research on the spatial distribution of supply and demand for urban green spaces often overlooks residential green spaces,which are more accessible.This study is hence conducted to investigate the impact of residential green spaces on the balance of supply and demand for urban green spaces,with an aim at providing scientific bases for increasing the urban green space equilibrium and improving the residents'welfare.[Method]With the streets in Wuhou District of Chengdu City as the basic unit,the balance of urban green spaces is analyzed under two scenarios:including and excluding residential green spaces.The current distribution of supply and demand of urban green spaces in Chengdu is comprehensively compared using ecosystem service quantification methods.The supply-demand relationship of ecosystem services in each street is examined through location entropy to assess the contribution of residential green spaces to the distribution of urban green space supply and demand.[Result]The distribution of supply and demand for urban green spaces in Chengdu is uneven.When residential green spaces are taken into account,the overall balance of urban green space distribution improves by 68.1%.In the analysis of local balance,the number of imbalanced units decreases.[Conclusion]The inclusion of residential green spaces enhances the balance of supply-demand distribution for urban green spaces.The results provide new ideas for optimizing the structure and the layout of urban green spaces,i.e.,protecting existing park green spaces,optimizing the layout of residential green spaces and park green spaces,and improving the quality of urban green spaces.
