摘要
为准确客观地反映湿地水环境情况,分别运用改进内梅罗污染指数法及模糊数学法对昭君岛湿地的平水期、枯水期、丰水期水质进行评价,以2015-2016年昭君岛湿地水质监测数据为基础,选取总氮、总磷、氨氮、化学需氧量(COD)为水质影响因子,两种方法的评价角度不相同但评价结果基本一致,即平水期及枯水期水质优于丰水期,各影响因子均有不同程度超标现象,湿地水质无法满足Ⅲ类水体功能要求,相关部门需加强湿地水体污染防治。
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.
