| Abstract:【Background】The spatial variation of water salinity is very different because of the differences in the environment and climate change background. 【Objective】In this context, analyzing the spatial variation of water salinity in the Ebinur Lake region can help to understand the soil water salinity integration pattern more reasonably. 【Method】In this paper, we divide the Ebinur Lake region into three target areas: oasis, desert and lake area, and analyze the spatial variability of soil water and salt in the three areas by using statistical and geostatistical methods. 【Result】The study showed that the soil salinity in the surface layer of the oasis, desert and lake areas was in the order of desert, oasis, lake area, while the water content was the opposite; the soil salinity in the oasis, desert and lake areas showed high correlation in 10-20 cm and 20-40 cm, with correlation coefficients of 0.913, 0.966 and 0.941, respectively. The soil salinity and water content of different soil layers in the oasis region showed similar trends of Moran's I coefficient with increasing spatial distance. 【Conclusion】This paper provides a preliminary understanding of the spatial distribution characteristics of soil water and salinity in autumn under different environmental backgrounds in the Ebinur Lake area, which provides a scientific basis for crop irrigation management and soil salinity management in the Ebinur Lake area.
