The method is based on the electro － chemical sensor measuring five water quality parameters, namely temperature (T), dissolved oxygen (DO), oxidation reduction potential (ORP), electrical conductivity (K) and pH. Combined with the K-star model of the mathematical model and the sur －face water environment quality standard (GB-3838-2002) as reference, the unknown water quality category is obtained by classification and calculation of K -star model.At the same time, the water quality comprehensive index (WQCI) evaluation method was optimized by a series of experiments. By comparing the results of the experiments with the statistics released by the environmental protection agency ,we find the results are basically consistent .Compared with other water quality compre － hensive evaluation method, this method can realize the integration of the testing instruments which is used to detect the pa －rameters. It is easy for the on-site and remote automatic analysis.If combined with network technology, it can realize the
