By using GIS and geostatistics, combining with field monitoring of soil salt content in May of 2014, the spatial variability characteristics of soil salt content in Yutian Oasis was investigated. The results indicated that the soil salt content was distributed unevenly, mainly in arc, patchy and stripped shapes, showed a certain spatial agglomeration in genneral. Soil salt content was mainly influenced by desertification and vegetation coverage. The study was beneficial to the rapid diagnosis of soil salinization and to provide the basis of decision-making for improving the efficiency of land use and ensuring the sustainable development of regional farmland.
