The characteristics and spatial distribution of surface saline soil is important to study in Yinbei area of Ningxia Province. This paper uses the methods of geographic statistics to analyze the variation of soil water( 0- 25 cm) and salt,spatial variability in experimental plots. The results show that surface soil moisture content and salt content was gradually increased over time in summer. Second,the coefficient of variation of soil moisture is higher than the soil salt's. According to statistical calcula...
