利用模糊综合评价及香农威纳指数对2011-2015年西溪湿地水质进行评价。结果显示：西溪湿地水质总体较好，水体较清洁；但总体有下降的趋势，且水质变化呈季节性，冬春季水质优于夏秋季。水中总氮污染问题应引起重视。

Evaluated the water quality of Xixi Wetland from 2011 to 2015 by using fuzzy comprehensive evaluation method and Shannon-Wienner index. The results indicated that the overall water quality of Xixi Wetland was good and clean; but there seems to he a downward trend, water quality change was seasonal, and the water quality in winter and spring was better than summer and autumn. The problem of pollution of total nitrogen in water should be concerned.
