Abstract :
In order to set up a water quality assessment system for Zhanghe river fittingly, a fuzzy comprehensive evaluation model based on fuzzy theory is studied. The application of this method to evaluate the water quality in Xida section is given as an example for demonstration. According to the environmental quality standard of surface water, the membership function is established. So as to ensure the weight value of each evaluation factor, using the principle of maximum membership function, the result is similar to the actual situation.
