Ecological fragility of wetlands in Sanjiang Plain

Abstract

Abstract: This paper presented an index system and a method for evaluating the ecological fragility of wetlands.The indexes were chosen according to the properties and the development pattern of wetland ecosystem in Sanjiang Plain,the values of weighing the relative importance of the indexes were computed by the method of “APH”(The Analytic Hierarchy Process)and the fragility level was evaluated by the method of multi-indexes.A case study showed that the ecological fragility of wetlands in Sanjiang Plain was prominently high.The availability of this method and this index system was also discussed in the paper.

Key words: Sanjiang Plain, Wetlands, Ecological fragility, AHP
