In order to accurately and objectively reflect the water quality of wetlands,the improved Nemerow pollution index method and fuzzy mathematics method was used to evaluate the water quality of Zhaojun island wetland.Based on the monitoring data of Zhaojun island wetland in 2015-2016,the total nitrogen,total phosphorus,ammonia and COD were the influencing factors of water quality.The evaluation angle of the two methods was different,but the evaluation results were basically the same:Water quality in the plain and dry season was better than that in the wet season,and all the influencing factors were over standard in different degrees.Wetland function decline,the water quality could not meet the class Ⅲ water function,and the relevant departments need to strengthen the wetland water pollution control.
