Abstract:: Using statistical analysis and geostatistical analysis, spatial distribution of soil organic carbon in depth of 0—20 cm in the Bortala River Basin was investigated. The results showed that the semivariance analysis indicated that soil organic carbon change process had obvious size difference. Organic carbon distribution in the upper and lower reaches of Boratala River Basin can be well described by Gaussian model, and the organic carbon distribtution in the middle reaches can be fitted by the linear model. The ratio of nugget value and base value indicates that the spatial correlation of soil organic carbon content in the Bo River upper is very weak, the random factors (such as fertilization, tillage, cropping systems and other human activities cause spatial variability) play the major role; soil organic carbon contents in the middle and lower reaches exhibited moderate spatial correlation, indicating that structural factors (such as climate, parent material, topography, soil type, natural factors) and random factors play the roles. The Kriging interpolation showed that: (1) the spatial distribution characteristics of soil organic carbon present as the plaque in Bortala River Valley, which is consistent with the distribution of cultivated land; (2) the maximum value of the whole basin appeared in the downstream because of the cultivation mode and large amounts of nutrients moved from the upstream of river, soil deposition in the lower reaches due to irrigation; (3) soil organic carbon content around Bole City is the minimum, which may be related to the city and industry land around Bole.
