Abstract:: Based on the regional variable theory, using GPS positioning technology, from July to August in 2005, according to Yuepuhu County designated soil sampling, soil sampling levels of 0-30 cm, 30-60 cm, 60-100 cm, and 100-200 cm, a total of 118 sampling points, with the GIS technical supporting, the statistic’ semi-varfogram and kriging spatial interpolation, quantitative analysis Yuepuhu County at different levels of spatial heterogeneity of soil salinity. The results show that: Yuepuhu County, generally high levels of soil salinity, the means of soil salinity are 17.44 g/kg, 11.67 g/kg, 9.10 g/kg and 8.14 g/kg. And the variability is large, the coefficient of variation is 0.877～0.959, close to the strong variability. 0-30 cm, 30-60 cm, and 60-100 cm, soil salt distribution model for the theoretical part of exponential model, 100-200 cm are spherical model. Spatial correlations of soil salt levels belong to moderate. Between the different layers of spatial autocorrelation, a clear difference in the scope, from surface to depth, soil salinity increased gradually from the related areas. In the space character, the salinization of Yuepuhu County are dire adjective, the layers of 0-30 cm, areas which soil salinization happened heavily take up 40.42% of the total, and solonchak is 47.87%. In the horizontal direction, spatial pattern of soil salinity, mainly in high-value areas located in Yuepuhu Town, Yuepuhu County, Seyeke County, Aqike County and Tieremu County. Research efforts to prevent Yuepuhu County soil secondary salinization and reasonable use of soil resources to provide the basis of decisions.
