摘　　要：城市公园绿地为居民提供了重要的生态系统文化服务,在促进居民身心健康和提高社会福祉方面发挥着关键作用。以典型山地城市重庆中心城区为例,构建供需匹配评估体系,利用多源数据量化供给与需求,识别供需平衡与协调发展关系。结果表明:(1)重庆市中心城区城市公园绿地生态系统文化服务供需具有显著空间异质性,供给呈北高南低、分散布局的格局,需求呈中心高、外围低的格局;(2)生态系统文化服务供需失衡特征显著,其中52.38%的组团文化服务供给滞后,33.33%的组团属于供给超前状态;供需耦合协调指数平均值为0.50,协调发展程度空间分布呈“中心高、外围低”格局;(3)综合分析供需均衡与耦合协调结果发现,由于供给超前导致了外围城市组团的失调发展,而城市中心区域组团在供给滞后状态下维持了中等水平协调发展程度。总体来看,重庆市中心城区各组团存在不同程度的公园绿地生态系统文化服务供需错配,基于评估提出针对性的城市公园绿地优化策略,可为公园绿地的合理配置与规划提供重要支持。Urban parks provide residents with significant cultural ecosystem services(CES) and play a key role in promoting their physical and mental health,contributing to human well-being.With the rapid urbanization in China,many cities have been generally facing the challenges of uneven distribution of urban parks and mismatches of supply and demand in built-up areas.Mountainous cities have unique natural environments that are different from those in plain cities.With the highly dense population,mountainous cities are facing more severe pressure of intense land use,and complex terrain,which may lead to a serious imbalance in the supply and demand of urban parks.This study aims to identify the supply-demand spatial matches and mismatches of cultural ecosystem services(CES) provided by urban parks in polycentric mountainous cities.To do so,we constructed a supply-demand matching assessment framework by taking the central city of Chongqing,a typical mountainous city,as an example.It provided a new approach by utilizing a multi-dimensional indicator system to analyze the CES supply-demand balance and coordination relationship of urban parks based on muti-source data.The result shows that:(1) The supply and demand of cultural ecosystem services in urban parks in Chongqing has a significant spatial heterogeneity.The pattern of CES supply is distributed a high in the north and a low in the south,while the high demand is concentrated in the urban centers.Compared to the demand,the CES supply showed a more decentralized pattern.(2) The results showed a significant spatial imbalance between the supply and demand of urban parks,with 52.38% of the clusters having an insufficient supply of cultural services,and 33.33% of the clusters in the condition of over-supply.The coupling coordinated degree between CES supply and demand demonstrated a gradual decline from the center to the periphery,with an average value of 0.50;(3) Based on the assessment of supply-demand balance and coupling coordination,our findings demonstrated that the unc
