| Abstract: | The contents of organic carbon and water of different plant processes in soil profile of NingXia GuYuan are measured and analyzed. The result shows that the contents of organic carbon and water in soil profile of plantation and shrubbery are higher than that of grassland and upland obviously. Meanwhile the distribution of the organic carbon and water contents presente a decreasing trend with the increase in soil depth of different plant processes, Comparatively there is a evident decrease of the organic carbon and water contents in different layers of plantation and shrubbery soil. |

| Keywords: | plant process soil profile the content of organic carbon water content |
