摘要
城市生态系统健康是城市综合发展过程中对生态环境所产生影响的反馈。目前对于此类型的评价模型和方法较成熟,但是缺乏一套相对完善的评价指标体系。本文根据自然—社会—经济复合生态系统理论构建长沙市生态系统健康评价指标体系。结合大数据和传统数据,用基于熵权的模糊综合法对2010—2020年期间长沙生态系统健康和整体协调度进行评价。研究结果表明:1)2010年芙蓉区城市生态系统健康隶属等级最高,为0.55。望城区耦合协调度水平最高,为0.721。2)2020年芙蓉区城市生态系统健康隶属等级最高,达到0.564且协调水平最高,为“良好协调”。3)2010—2020年期间,长沙市各区的生态系统健康均得到改善提高,但是耦合协调度等级变化较大。
The health of urban ecosystem is the feedback of the influence of ecological environment in the process of urban comprehensive development.At present,the evaluation models and methods of urban ecosystem health are mature,but there is a lack of a set of relatively perfect evaluation index system.Based on the theory of natural-social-economic complex ecosystem,this paper constructs the index system of urban ecosystem health evaluation in Changsha City.Combining big data and traditional data,the fuzzy comprehensive evaluation method based on entropy weight was used to evaluate the health and overall coordination degree of urban ecosystem in Changsha City during 2010—2020.The results showed that:(1) Furong District had the highest level of urban ecosystem health in 2010,which was 0.55.Wangcheng District has the highest level of coupling coordination,which is 0.721.(2) In 2020,Furong District had the highest level of urban ecosystem health,reaching 0.564 and the highest coordination level,which was considered as “good coordination”.(3) During 2010—2020,the ecosystem health of all districts in Changsha City was improved,but the coupling coordination degree changed greatly.
