摘　　要：山地型高密度城市生态系统文化服务(CES)供需空间关系复杂,在城市人居环境高质量发展的新阶段,以供需视角对城市CES空间关系进行量化研究,有助于城市生态系统价值的效益转化及整体社会福祉提升。以山地型城市重庆为研究区域,基于多源数据运用Arc GIS分析技术、计算机视觉识别及空间相关性分析等方法,对CES供给及需求的空间分布和特征、供需平衡及空间关系进行了量化研究。结果表明:1)重庆中心城区CES供给呈现出“大聚集,小分散”的空间格局,且具有“中心-外围”的聚类特征,高-高值聚集区主要连片分布在建成区及周边,而低-低值聚集区则主要分散布局于外围地带,山地型本底自然条件对其影响显著;2)CES需求空间分布极不均衡,需求高值区向心性分布特征明显,但不同类型CES需求空间分布有所差异;3)CES供给与需求之间存在较弱的空间结构相似性,供需平衡表现出显著的空间异质性,供需不匹配问题突出,“两江四岸”核心地带供给压力大,而外围区域供给潜力大,但实际需求低。研究结果可为山地型城市CES调控与优化提供理论支撑。The supply and demand spatial relationships of cultural ecosystem services(CES)in mountainous high-density urban ecosystems are intricate.In the new phase of high-quality development in urban living environments,conducting a quantitative study on the spatial relationships of CES in cities from a supply-demand perspective contributes to the transformation of the value of urban ecosystems and enhances overall social well-being.Taking the mountainous city of Chongqing as the study area,a quanti⁃tative study of the spatial distribution and characteristics of CES supply and demand,the balance between supply and demand,and the spatial relationship has been carried out based on multi-source data using ArcGIS analysis techniques,computer vision recogni⁃tion and spatial correlation analysis.The results show that:1)The CES supply of Chongqing presents a spatial pattern of“large aggregation and small dispersion”,and has a clustering feature of“center periphery”.The natural conditions of the mountainous background have a significant impact on it with high-high value aggregation zones mainly located in and around the built-up areas in a continuous manner, while low-low value aggregation zones are mainly dispersed in the peripheral zones, which is significantlyinfluenced by the natural background conditions of the mountainous terrain;2) The spatial distribution of CES demand is extremelyuneven, with a clear centripetal distribution characteristic of high-value demand areas, but with differences in the spatial distribu⁃tion of different types of CES demand;3) There is a weak spatial structural similarity between CES supply and demand, and thebalance of supply and demand shows significant spatial heterogeneity, with a prominent mismatch between supply and demand,with the core area of the“ Two Rivers and Four Banks” under great pressure of supply, while the peripheral areas have a high CESsupply, but low actual demand. The results of the study can provide theoretical support for the regulation and optimisation o
