摘要
为了研究汉源湖水体富营养化状况,本文于2021年对汉源湖7个断面进行了水质监测,并建立了水体富营养化模糊评价模型,将模糊评价结果与综合营养状态指数法评价结果进行了比较。结果表明,汉源湖7个监测断面均属于中营养水平,模糊评价法与综合状态营养指数法评价结果一致。模糊评价法通过隶属度值能更直观的表征相关评价水体趋于富营养化相应等级的程度。
In order to study the eutrophication status of Hanyuan Lake,this paper monitored the 7 water quality monitoring sections of Hanyuan Lake in 2021,established a fuzzy evaluation model for the water eutrophication,and compared the results from fuzzy evaluation and from the comprehensive nutritional state index method.The results showed that the 7 monitoring sections of Hanyuan Lake was on the state of middle-eutrophication,and the evaluation results of fuzzy evaluation method was consistent with the comprehensive state nutrition index method.The fuzzy evaluation method can more intuitively interpret the degree of eutrophication of the water quality through the membership value.
