摘　　要：快速城市化及城市扩张过程中,城市绿地生态系统文化服务(CES)供给与公众需求空间失衡问题日益凸显。如何有效识别城市绿地文化服务供需空间匹配特征是优化绿地空间布局、提升绿地服务效率的关键所在。本研究以重庆市中心城区为研究范围,基于地理空间数据等多源数据,运用GIS分析技术、空间相关性分析等方法,构建了城市绿地文化服务供需评价指标体系和分析框架,识别了山地城市绿地文化服务供给与居民需求的空间匹配类型。研究发现CES供给具明显的空间聚集性,全局莫兰指数为0.720,呈现为“大核—次核—小核”的分布形态,CES需求全局莫兰指数为0.834,呈现中心高外围低、西高东低的空间格局,双变量自相关分析显示供给与需求之间存在空间结构相似性,CES供需关系整体上较好,但一些关键区域匹配失衡压力较大。根据供需平衡关系特征,将研究区识别为六类空间类型,并对每种类型提出了CES优化提升路径。研究结果可为山地城市绿地生态系统文化服务优化路径提供理论支撑与实践借鉴。Urban green spaces are an important component of urban natural ecosystems,with significant ecological,economic,and social value,providing multiple services in both material and non-material aspects for urban residents.Among the four major service types of ecosystem supply,regulation,support,and culture,the first three are the living conditions and environment they provide to humans at the material level,while cultural ecosystem services(CES)are the nonmaterial benefits they provide at the spiritual level.Research has confirmed that CES can promote human physical and mental health and contribute to the overall improvement of welfare benefits.The relationship between human welfare and urban green space CES is not only related to the supply capacity of green space habitats,but also to the demand level of urban residents within the service scope.However,in the process of rapid urbanization and urban expansion,there is an imbalance and mismatch in the total supply and demand and spatial allocation of CES.Relevant studies have shown that the spatial distribution and correlation of supply-demand of urban green space CES affect its ecosystem service efficiency.Therefore,effectively identifying the spatial matching characteristics of supply-demand for urban green space cultural services is the key to improving green space service efficiency,optimizing green space layout,and promoting high-quality development of living environment.At present,the quantitative evaluation of CES supply and demand is still in the exploratory stage,and there are certain difficulties in constructing the supply and demand relationship of urban green space CES.Due to significant differences in the scale and indicators of supply and demand research,there is currently no unified model that can accurately establish a connection between supply and demand,and the research results are also difficult to provide guidance for coordinating green space resources in landscape planning practice.Therefore,how to accurately identify the differences in the curren
