The Application Research of Fuzzy Comprehensive Evaluation Method for Water Quality Assessment--Take Yangtze River Basin as an Example
In this paper,fuzzy mathematics is introduced to the basin water quality evaluation,established the suitable for the Yangtze river basin water quality evaluation model.According to the 19 monitoring stations data received in the Yangtze river basin in 2011,using an improved fuzzy comprehensive evaluation method for comprehensive evaluation of water quality in Yangtze river basin,and analysed based on the usage of SPSS statistical software.The calculation result shows that besides Leshan Minjiang river bridge section in Siehuan (Grade Ⅱ),Changsha Newport section in Hunan (Grade Ⅰ tend to Grade Ⅱ),Nanchang Chucha section in Jiangxi(Grade Ⅱ tend to Grade Ⅲ),other section water quality all belong to Grade Ⅰ,the water quality in Yangtze river valley in 2011 is good.
