Abstract: Based on the observed data of groundwater depth of Fukang, Xinjiang, from 1993 to 2015, the semivariogram analysis and Kringing Spatial Interpolation Analysis based on the geostatistics were carried out to examine groundwater depth, using SPSS, GS+ and ArcGIS. The results showed that the groundwater depth of oasis in Fukang had a strong spatial correlation. The changes of groundwater level were mainly caused by structural factors, but were less influenced by random factors. The depth of groundwater gradually deepened from northwest to southeast. The groundwater depth presented a temporal decline in 1993-2015, with an obvious reduction occurring in areas with groundwater level less than 8 m, which mainly concentrated in the oasis being influenced by human activities. Therefore, the human activities have strong impacts on the depth of groundwater in this area.
