Abstract:

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. 1)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 harmonie management for determination of more rational land use and mode of production in polders.

Key words: polder, water ecosystem, service function, Taihu basin, quantitative assessment
