Abstract：Based on the measured data of the water quality of 16 monitoring sections in the surface-ground water source in 2013, the hierarchical clustering R-typed factor analysis method and Ward method were used to analyze the spatial heterogeneity laws of the water environment in the centralized drinking water source in the plain terrain of Wuwei City. The results showed that the contamination in the drinking water source in the plain terrain of Wuwei City tends to transfer from north to south. The water pollution of 16 monitoring sections in the surface-ground water source in May 2013 tends to transfer from north(Bb5)to middle(Aa6,Aa7). The water pollution in August 2013 tends to transfer from middle(Bb3,Aa7)to south(Ba5,Aa5). The main pollutants include:NO3-N,permanganate index,chloride,volatile penols,total coliform group,sulphide,Se,total hardness. These data could provide the basis for both the division of the functional district and the comprehensive control of the water environment in this area.
