摘要: 选取不同类型退化湿地的典型退化指标,如湿地面积变化率、水源补给状况、地表水水质、濒危物种数和种群数量变化率、植被覆盖变化率等作为湿地退化状况的评价指标,将湿地的退化程度划分为4个等级:未退化、轻度退化、重度退化和极度退化,并对10处滨海国际重要湿地和22处内陆国际重要湿地的退化状况进行了评价。评价结果表明,2个湿地是严重退化,1个湿地是轻度退化,其余29个湿地是未退化。

关键词: 湿地, 退化, 评价指标, 退化状况

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
