摘要
根据长江口湿地现状,构建了长江口边滩湿地生态功能价值评估指标体系,并采用层次分析法对典型湿地分布区九段沙、崇明东滩和南汇边滩进行了评价。评价结果表明,长江口边滩湿地生态状况总体良好;因受人类活动影响程度不同,九段沙湿地状况最优,其次为崇明东滩湿地,南汇边滩湿地相对最差。评价结果与实际情况相符,说明所构建的评价指标体系合理有效,模型的构建为河口湿地开发、利用、保护提供了理论基础。
The evaluation system of eco-function for foreshore wetland of Yangtze River estuary was established with consider-ation of the actual conditions in the area. Three regions where the typical wetlands distributed, i. e, Chongming Dongtan, Jiu du-ansha, Nanhui foreshore, were evaluated by using AHP. The evaluation results showed that the wetlands in the estuary of Yangtze River was good in general, which were influenced by human activities at different degree;the situation of Jiuduansha wetland was the best, followed by Chongming Dongtan wetland and Nanhui foreshore wetland. The evaluation results were in accordance with the practical condition, so the evaluation index system was effective, which could provide a theoretical basis for the development, utilization and protection of wetland.
