This paper quantitatively analyzed the seasonal variation and correlation of saline soil water, salt and temperature in Yutian Oasis, located in southern Tarim Basin of Xinjiang by using ENVI 5.1, ArcMap10.2, Origin 8.5 and SPSS 20.0 software and the measured data of soil water contents, electrical conductivities and temperatures in different layers of soil profiles in different sites. The results showed that soil water contents, temperatures and electrical conductivities in all layers of all soil profiles increased gradually from June to August. Water content was highest in 60 ~ 100 cm layers in No.5 and No.8 sampling sites. Electrical conductivities were highest in 0—20 cm layers in No.8 and No. 22 sampling sites and in 40～60 cm layers in No.5 and NO.22 sampling sites. Water contents, temperatures and electrical conductivities in all layers of all soil profiles were higher in Autumn and Summer than in Winter and Spring. Soil water contents and electrical conductivities of No.16 and NO.22 sampling sites had significantly positive correlations, and the correlation coefficients were the highest in 60 ~ 80 cm layers, which were 0.970** and 0.987**, respectively. The above results indicate that the analyses on the seasonal variation and correlation of saline soil water, salt and temperature is helpful for the rapid diagnose of soil salinization, and they can provide the reference and guidance for the sustainable development of ecological environment and agriculture in Yutian Oasis.
