摘　　要：以衡阳市中心城区为例,结合城市绿地生态系统服务功能特点,采用生态模型法和价值当量法测算空气净化、气候调节、休闲娱乐和水源涵养4项生态系统服务的供给和需求,并分析其空间匹配关系。结果表明:1)生态系统服务空气净化、气候调节、休闲娱乐和水源涵养供给能力分别为21.75×10^(6)元、167.01×10^(8)元、50.42×10^(6)元和288.83×10^(6)元,空间上总体呈现中心低四周高的空间分布特点。2)各生态系统服务需求分别为73.77×10^(3)元、2076.71×10^(8)元、2532.94×10^(6)元和630.27×10^(8)元,其空间呈现中心高四周低的空间特征。3)各生态系统服务的供需匹配度从高到低依次是空气净化(0.51)、气候调节(-0.57)、休闲娱乐(-0.66)和水源涵养(-0.68),且具有明显的空间差异性,空气净化匹配度高值区主要分布在城区周边区域,其他三项生态服务高值区则主要分布在研究区的东北部。Taking the central urban area of Hengyang city as an example,this paper uses ecological model method and value equivalent method to calculate the supply and demand of four ecosystem services,including air purification,climate regulation,ecological leisure and water conservation,and analyzes their spatial matching relationship.The results showed that:(1)The supply capacity of the four ecosystem services including air purifica-tion,climate regulation,ecological leisure and water conservation is 21.75×10^(6)yuan,167.01×10^(8)yuan,50.42×10^(6)yuan and 288.83×10^(6)yuan,respectively and the spatial distribution is low in the center and high in the surroundings.(2)The demand for each e-cosystem service is 73.77×10^(3)yuan,2076.71×10^(8)yuan,2532.94×10^(6)yuan and 630.27×10^(8)yuan,respectively.The spatial characteristics of the ecosystem service demand were high in the center and low around.(3)The matching degree of supply and demand of each ecosystem service from high to bottom is air purification(0.51),climate regulation(-0.57),ecological leisure(-0.66)and water conservation(-0.68),with obvious spatial difference.The regions with high matching degree of air purification are mainly distributed in the surrounding areas.The other three high value areas of ecological services were mainly distributed in the northeast of the study area.
