摘　　要：当前城市发展已进入存量时代,人们对于绿色空间的诉求愈发强烈,区域发展程度不一导致不同空间公园绿地服务水平差距较大,中心区域往往供不应求,而边缘区域反之,仅从二维平面空间考虑公园绿地分布已不再符合城乡协调发展和公园绿地服务公平需要,公园绿地供给与需求之间的矛盾日益凸显,优化公园绿地空间布局和生态系统服务效率急迫需要明确其供需平衡关系,通过生态、社会、物质三大维度12类供需指标构建供给需求指标体系,揭示朝阳区公园绿地供给能力与需求水平在空间上的真实匹配状况,结合耦合协调模型探究朝阳区公园绿地空间整体供需基本特征规律。Urban developme nt has entered the era of stock from increment,people have an increasingly strong demand for green space.Different regional development degrees lead to a large gap in the service level of different Spaces of park.The central area is often in short supply,while the marginal area is on the contrary.Considering the distribution of park only from the 2-dimensional plane space is no longer in line with the coordinated development of urban and rural areas and the fair service of park,the contradiction between the supply and demand of park green space has become increasingly prominent.The balance between supply and demand is urgently needed to optimize the spatial layout of park and the efficiency of ecosystem services.This paper constructs a supply-demand index system through 12 types of supply and demand indexes in 3 dimensions of ecology,society and material,reveals real spatial matching between the supply capacity and demand level of park,explores the basic characteristics of the overall supply and demand of park green space in Chaoyang District with the coupling coordination model.
