Land resource is the foundation for human being to live. The soil erosion results in land degeneration, environment depravation, and influences weather change. China is a developing country, how the country use land resource will definitely affect environmental change. This paper sets the type of land resource as a unit based on defining soil erosion index. Under the GIS and RS supporting, we put these coverages into GRID which square is 100m, and overlay these two coverages. Then we get what we need datum. By analysis these datum, we analysis the type and intension of soil erosion, set forth the soil erosion background of land resource. Therefore, we can explore the relationship between soil erosion and land resource. Finally, we make analysis in region. The result is that we should mainly plant tree in south of China and plant grass in north of China.
