摘　　要：采用模糊综合评判的方法对2003年双台子河口湿地的水环境质量进行了综合评判。利用加权平均模型及最大隶属度原则,根据2003年双台子河口湿地的水质监测资料计算出评价水质情况的模糊子集,得出结论双台子河口湿地的水质等级为Ⅳ,水环境质量较差。模糊综合评判法在湿地水环境质量评价中的运用为双台子河口湿地水资源规划及合理开发和利用提供了有利依据。This article has researched on Shuangtaizi estuarine wetland water environment quality in 2003 by fuzzy comprehensive evaluation. The research calculated water quality evaluation of fuzzy subset according to the 2003 Shuangtaizi estuarine wetland water quality monitoring data. The calculating results were based on the weighted average model and maximum membership principle. It showed that Shuangtaizi estuarine wetland water quality grade was Ⅳ and water environment quality was bad. The use of fuzzy comprehensive evaluation in wetland water environment quality evaluation could offer a favorable gist for the planning of Shuangtaizi estuarine wetland and the adjustment of using water resources structure.
