基于生态系统服务簇时空演变的生态功能分区研究——以安徽省芜湖市为例

Ecological Function Zoning Based on Spatiotemporal Change of Ecosystem Service Bundles:A Case Study of Wuhu City in Anhui Province

科学划定生态功能分区,对生态文明建设和国土空间优化具有重要指导意义。基于生态系统服务簇定量化分析视角,运用长时间序列数据,综合多种模型算法分析快速城市化背景下芜湖市村域尺度生态系统服务簇时空演变特征。依据其演变规律将芜湖市域分为主导生态系统服务稳定供给区和波动供给区2个功能大区,并进一步细分为都市生态修复、长江生态保护、生态农业维护、丘陵生态保育、生态农业建设、都市农业发展和丘陵生态恢复区7个功能区,并提出差异化的生态系统管理建议。研究有助于提升生态功能分区客观性和科学性,为生态系统管理提供依据。

Scientific ecological function zoning has important guiding significance for the construction of ecological civilization and the optimization of land space.Based on the perspective of quantitative analysis of ecosystem service bundles,and by using long-term data and multiple models,this paper analyzes the spatiotemporal changes of ecosystem services bundles at village scale in Wuhu City under the background of rapid urbanization.According to ecosystem service bundles evolution,Wuhu City is divided into two functional areas:the dominant ecosystem service stable supply area and the fluctuating supply area,and further subdivided into seven functional areas such as urban ecological restoration area,Yangtze River ecological protection area and ecological agriculture maintenance area.This study also puts forward differentiated ecosystem management and control suggestions to help improve the objectivity and scientificity of ecological function zoning,and provide a basis for ecosystem management.
