The Indicators for Evaluating Wetlands Degradation in China

Abstract

Abstract: The paper collects the evaluating indicators that could cover the typical characteristics of degraded wetlands in different types,such as loss of wetland area,the status of water supply,the quality of surface water,rate of vegetation coverage,number of endangered species and the variation rate of their population.By utilising the proposed assessment criteria wetlands can be classified into four categories: minor,mild,severe and extreme degradation.By applying the evaluation indictors,the degradation status of 10 coastal and 22 inland international important wetlands was evaluated.The results showed that 2 wetland sites were under severe degradation,one with mild degradation and the other with minor degradation.

Key words: wetlands, degradation, evaluation indicators, degradation status
