Integrated Fuzzy Evaluation of Raw Water Eutrophication Based on GIS

Abstract:

To do a research about raw water eutrophication of water plants in Hangzhou, samples of raw water in Jiuxi, Xiangfu, Nanxing, Qingtai Plant were collected and analyzed to get more than 10 water quality indexes. Turbidity, DO, COD, TN, NH₃-N and CHL-a serving as example. supported by GIS, integrated fuzzy evaluations of raw water eutrophication in July and December were completed applying entropy weight method. The result shows that in terms of the nutrient degree, Xiangfu is the most qualified while the least one is Qingtai. Overall, raw water in December is of higher quality than July.
