This paper discussed the spatial distribution of soil erosion in China at the end of the 20thcentury based on the second national soil erosion survey. The result indicated soil erosion is still theprime environmental problem in China. Soil erosion mainly occurs in the western regions of China,and the slight erosion type, ion the whole, exerts the greatest impact on soil erosion pattern. Thedistribution of water erosion shows the impact of landforms: slight water erosion mainly inmountainous and hilly areas, and half of violent water erosion on the loess landforms. Farmland,forestland and grassland are the major land use types of slight hydraulic erosion distribution, while theserious hydraulic erosion and slight wind erosion mainly occur on grassland. Thus, the conservation ofthe grassland is the key to either hydraulic and wind erosion control. The huangmian soil (a major typeof cultivated soil developed from loess mother material) is the one facing the most serious threat fromsoil erosion in Chinas soil resources. Further discussion on the soil erosion distribution still needs moreresearch on the method and relevant data analysis.
