Water Quality Analysis of Guantai Section in Yuecheng Reservoir Based on Fuzzy Evaluation

According to the "environmental quality standard for surface water" (GB3838-2002), the corresponding membership function was established by combining water quality monitor data and the analysis results of Guantai section, and adopting fuzzy mathematics elementary theory and the fuzzy evaluation model, thus via the kind of method the water quality analysis of Guantai section in Yuecheng reservoir based on fuzzy evaluation was studied in this paper. The results indicate that the water quality condition change weakly and the water quality grade range from II grade to III grade. At the same time, this method is benefit for solving the evaluation of water quality of multiple-factor. Moreover, for the precision of evaluation results, it is effective to establish the regular routine water quality monitor network and the pre-arranged planning of emergency monitor, so it can ensure the reasonable, permanent use of the water resource and the sustainable development of the society, economy and environment. © 2012 American Scientific Publishers.
