Abstract: Taking the Sangong River basin in Fukang County of Xinjiang as an example, this paper studied the characteristics of soil fertility at different sampling sites,and analyzed its spatial heterogeneity and pattern with the help of geostatistics and geographic information system. The results showed that the variation coefficients of major soil fertility indexes ranged from 5.00% to 66.77%, with an approximately normal distribution and characterized as space variation structure. Soil organic matter and total N had a similar spatial variation tendency, and a significant correlation. Soil available P and K also had a similar spatial pattern. The soil spatial pattern was deeply affected by human activities.
