摘　　要：城市绿地为城市发展提供各类生态服务功能,对城市绿地各类生态服务功能进行价值评估具有重要意义,但对于城市绿地生态服务价值评价方面的研究相对匮乏。本文以安徽省宿州市作为研究对象,在人群需求层次基础上,将生态服务功能与城市绿地功能结合,明确城市绿地生态服务功能。选取8个城市绿地生态系统服务指标,并参考相关统计年鉴,对该市2010年-2020年的生态服务价值进行动态分析,并利用全排列多边形图示法进行定量评价。结果表明:固碳价值与释氧价值占比之和最大,为75.153%;吸收氮氧化物、休闲游憩价值与吸收二氧化硫占比之和最小,为1.572%。11年间宿州市绿地生态服务功能由第4级提高到第1级。基于研究结果,提出了今后在城市绿地建设中的具体措施,对城市绿地生态服务价值进行评估,从而促进宿州市可持续发展与绿色低碳社会的实现。Urban green space provides various ecological service functions for urban development,and it is of great significance to evaluate the value of various ecological service functions of urban green space,however,research on the evaluation of urban green space ecological service value is relatively scarce at present.Therefore,taking Suzhou City,Anhui Province as the research object,on the basis of the level of population demand,the ecological service function is combined with the urban green space function to clarify the urban green space ecological service function.8 urban green space ecosystem service indicators were selected,and referring to the relevant statistical yearbooks,the city’s ecological service value from 2010 to 2020 was dynamically analyzed,and quantitative evaluation was carried out by using the full array polygon graphical method.The results show that the sum of carbon fixation value and oxygen release value is the largest,which is 75.153%;the sum of nitrogen oxide absorption,recreational value and sulfur dioxide absorption is the smallest,which is 1.572%.In the past 11 years,the ecological service function of Suzhou green space has been improved from the fourth level to the first level.Based on the research results,specific measures in the future construction of urban green space are proposed to evaluate the ecological service value of urban green space and promote the sustainable development of Suzhou and the realization of a green and low-carbon society.
