Abstract

The assessment of River water quality is the basis of water pollution control, environmental management and environment planning. In this paper, combining analytical hierarchy process(AHP) with fuzzy mathematics, we make a synthetic assessment of river water quality, the indicator system of fuzzy synthetic assessment of rive water quality is established. AHP is used to determine the weight of indicators .The fuzzy relationship synthetic matrix is obtained through processing multiple monitoring data of Qing River in Beijing, and then we make a synthetic assessment of Qing river water quality. The results of fuzzy synthetic assessment tally with the actual situation and have practical value.
