摘要:With the development of urbanization and the improvement of the people’s living standards, the contradictionagainst water supply and water demand is becoming more and more serious. And the development of theeconomy led to serious pollution of water, so it is essential to understand the water quality. This paperdiscussed the choice of the evaluated factors, the operations of the weight value, and compares with thestatus of the water quality in course of the evaluation. The conclusions indicated that the result of the fuzzymathematics evaluation represented the water quality of surface waters. The evaluation result was comparedwith that of the traditional method and the reported results. It is indicated that the performance of the proposedmodel is practically feasible in the application of water quality assessment and its application is simple.
