摘　　要：【目的】探析城市公园绿地生态系统文化服务(cultural ecosystem services,CES)的空间布局特征、供需匹配关系及优化策略,有助于提升公园绿地服务效能,优化公园绿地布局。【方法】以成都市主城区公园绿地为研究对象,构建包含供给潜力、供给机会、社会需求和物质需求4个维度的供需评价指标体系,结合耦合协调度分析,探究城市公园绿地CES供给水平、需求水平、供需匹配类型及耦合协调度的空间分布特征。【结果】1)CES供给水平呈现南高北低的组团式分布特征,需求水平则呈团状聚集的分布格局;2)CES供需匹配类型以高供给—高需求和低供给—低需求为主,而高供给—低需求和低供给—高需求类型占比较低,这表明CES在供需关系上表现出相对匹配的特征,但有较多供给缺口;3)CES供需耦合协调度整体欠佳,协调度最高的区域仅处于勉强协调等级。【结论】提出成都市主城区公园绿地CES供需的分类优化策略,供需高效区应提升绿地连续性,辐射周边低供给区域;供需过渡区应适度增加供给总量,完善公共服务设施;供需潜力区应提高供给溢出效应,增设公交服务设施。为提升研究区域内公园绿地CES效能、提高城市公园绿地规划与管理水平提供了依据。[Objective]This research explores the spatial distribution characteristics,supply-demand matching patterns,relationships,and optimization strategies of cultural ecosystem services(CES)in urban park green spaces.These efforts aim to enhance the efficiency of ecosystem services,promote spatial equity,and provide new perspectives and methodologies for studying CES in urban park green spaces.[Methods]Using 222 park green spaces in the main urban area of Chengdu as research objects,the research divides the area into 500 m×500 m grids for analysis.First,an evaluation indicator system and a supply-demand relationship model encompassing supply potential,supply opportunity,and resident demand dimensions are constructed to analyze the matching relationship and spatial distribution characteristics of CES.Second,the research applies a coupling coordination model to assess the coupling and coordination levels of CES supply and demand of urban park green spaces.Finally,based on the combined results of the supply-demand matching evaluation and the coupling coordination analysis,optimization strategies for CES in Chengdu’s park green spaces are proposed at the subarea level.[Results]The comprehensive supply level of CES in Chengdu’s park green spaces exhibits a cluster distribution pattern that is“higher in the south,and lower in the north”,with high-value areas concentrated in the central and southwestern parts of the main urban area,and low-value areas mainly distributed in the northeastern part.Meanwhile,the comprehensive demand level for CES displays an aggregated cluster distribution pattern,where high-demand zones are located in the central and southern part of the main urban area with high population density,strong human activity,intensive urban development,and well-developed facilities,while low-demand zones are found in the less densely populated and developed northeastern part.The supply-demand matching patterns are predominantly high supply-high demand and low supply-low demand,reflecting a low-level equilibr
