摘要：In recent years, due to the speeding up of urbanization, the water quality of Yongding river in Beijingis deteriorating. The Garden Show Park was built beside the Yongding river. In this paper, we havemade scientific and reasonable evaluation on the water environment of the park, tracking its ecologicaleffect in real time, to provide certain reference for the corresponding improvement measures. Firstly,we collected some water samples in the river, conducted an experiment later, and then we used theimproved special operation to calculate the fuzzy result, which is based on the principle of fuzzycomprehensive evaluation. At the same time, we increase the evaluation section, and balance theevaluation results of every section, it is concluded that the water quality level is: the third level (lightpollution), and it provides referential basis for the ecological restoration of the river.
