摘要
圩区作为南方平原水网地区一种重要的地理单元,圩区生态系统服务功能的研究具有重要意义.本研究选取太湖流域西北部地区的圩区,结合圩区数据的可获得性,对水域生态系统的供给、调节和维持功能进行定量评估,得到圩区水域生态系统服务功能的现状,并得出以下结论:1)圩区水域生态系统服务功能的总量和单位面积量在空间上都存在差异性;2)圩内生态系统服务功能的定位和恢复应参考服务功能的大小,因地制宜区别对待;3)圩内生态系统服务功能的管理应统一规划,协调管理,以确定更合理的土地利用以及生产方式.
Polder is an important geographic unit of the water net plain areas in southern China, and study of the polder water ecosystem service functions has important significance. We selected polders in western part of Taihu basin. On the basis of the available polder data, supplying, regulating, and maintaining functions of ecosystem were assessed quantitatively. The results show the following conclusions. I)The total quantities of water ecosystem service functions, as well as the amount of per unit area, are different in different spaces. 2) The management and recovery of ecosystem service functions in polders should refer to the results of assessment and be suited to the local conditions. 3) The management of ecosystem service function in polders should have a unified plann and harmonic management for determination of more rational land use and mode of production in polders.
