Research Of Geostatistics On Spatial Distribution Of Urban Surface Water Quality

The principles and methods of geostatistics are introduced. With the help of variogram, the contents of the water quality. NH4+-N, TP and COD, in rivers in the city of south China are analyzed. By using the Kriging, the special distributions of the content of NH4+-N, TP and COD are simulated. The contours of the spatial distribution of the urban surface water quality are shown intuitively. The research results provide a theoretical basis for governing the water environment.
