Abstract:

Discussing the scientific natural about using grey clustering method to evaluate water quality to provide the methodology reference for evaluation on water environment quality of wetlands in Daqing oil development zones,as well as for relevant foundation of environmental protection in midstream and downstream of the Songhuajiang River.The research explained the basic principle of grey clustering method and single factor pollution index method.The monitoring datum of water quality compared by some related math method. The results showed that Wanbao pool northwestern inlet and outlet side reached the quality assessment standard of the second-class, and the water quality of Anzhao river of Daqing Longfeng wetland reached the quality assessment standard of the third-class, and the water quality was better.The water quality of the other monitoring points was the fifth-class,and water pollution was quite serious.The research indicated that the grey clustering method about research datum was superior to that of single factor pollution index method.People should not ignore the environment protection of wetlands in Daqing oil development zones.
