摘要:

随着氮磷等营养盐类的不断排入湖库中,导致了水体的富营养化,使得水体透明度下降,产生异味,对人们的身体健康造成威胁。通过采用合适的水体富营养化评价模型,可以对水体的污染现状进行评价,得出正确的结论,以便采用适当的处理方式及时处理富营养化状况,减少对水环境和人体健康的危害。采用模糊综合评价法,将评价指标进行层次分析,并根据指标的相互关系,确定了各指标的权重,建立了模糊综合评价的数学模型。最终根据建立的评价指标体系、确定的评价标准和实测的湖库(巢湖、洱海和微山湖等)水质资料,得到了我国典型湖库的富营养化评价结论。评价结果与实际状况相吻合,说明该模型适合广泛应用

Abstract:

Along with the discharge of nitrogen and phosphorus nutrient continuously into the lake,it led to water eutrophication,made the water transparency decrease,produce odor,which was harmful to human health.Through the use of appropriate evaluation model of water body eutrophication,we can evaluate the status of water pollution,and draw a correct conclusion.Then the appropriate treatment of eutrophic conditions can be taken timely,which will reduce hazards to the water environment and human health.In this paper,the fuzzy comprehensive evaluation method was applied,the hierarchy analytic process of the evaluation index was conducted.According to the the relationship of the index,the weight of each index was determined,then the mathematical model of fuzzy comprehensive evaluation was established.Finally according to the evaluation criteria and measurement of lake and reservoir water quality data,the typical lake and reservoir eutrophication assessment conclusion was attained.The evaluation results and the actual situation were consistent,and the model is suitable for wide application
