摘　　要：为了建立适合于湿地的水质评价体系,将模糊数学的基本原理引入到湿地水质评价中,构建了湿地水质模糊综合评判模型,并以扎龙湿地为例进行了计算。评价结果证实,扎龙湿地从进水区、核心区到出水区污染程度有依次降低的趋势,这说明湿地对污染物有一定的净化作用。评价结果与实际对比,验证了评判模型的可靠性。In order to propose a water quality evaluation system suitable for wetland, a fuzzy comprehensive evaluation model based on fuzzy theory is developed. The application of this method to evaluate the water quality in Zhalong Wetland is given as an example for demonstration. The results indicate pollution degree reduces from infall area to core area, and to outfall area, which shows wetland could purify contamination when water flows through the wetland. The comparison between the results and actual situation shows that the evaluation results of this method are correct.
