中文摘要：

将模糊数学原理引入到湿地水质评价中,建立适合双台河口湿地的评价体系。利用模糊综合评判方法,对2010年双台河口湿地汛期水质进行综合评价。评价结果表明：核心区的最大隶属度为0.393,水质等级为Ⅲ级;缓冲区的最大隶属度为0.475,水质等级为Ⅳ级;试验区的最大隶属度为0.557,水质等级为Ⅳ级。从试验区、缓冲区到核心区,水体基本有逐渐转好的趋势,说明湿地对污染物具有一定的净化能力。

英文摘要：

In order to propose a water quality evaluation system suitable for Shuangtaihekou wetland,a fuzzy comprehensive evaluation model based on fuzzy theory is developed.Use fuzzy comprehensive evaluation method was used to evaluate the Shuangtaihekou wetland water quality in 2010.The results indicated the maximum degree of the core area was 0.393,the water quality was grade Ⅲ.The maximum degree of the buffer area was 0.475,the water quality was grade Ⅳ.The maximum degree of the experimental area was 0.557,the water quality was grade Ⅳ.The results indicated pollution degree reduced from infall area to core area,and to outfall area,which shows that wetland could purify contamination when water flows through the wetland.
