Abstract:: Yanqing County as one of Beijing’s five sand sources is located in the northwest of Beijing. It is an important part of the Beijing ecological environment construction project. This area belongs to fragile zone, which has been influenced by human irrational use of land, leading to the serious soil erosion problems. Through laboratory test and analysis, and using different methods such as statistics and correlation analysis, soil erodibility and its physicochemical properties of five kinds of land use types (Farmland, Orchards, Nurseries of young forest, Mountain shrub forest and Dirt road) in Beijing mountainous of Yanqing County were studied. The results showed that among different land use types, total porosity, water holding capacity of the soil, soil saturated water content and organic matter of mountain shrub forest soil were significantly higher than those of other land types (P < 0.05). Different land use types have the K value differences, which was followed in descending order: Dirt road (0.047 4) > Farmland (0.043 5) > Orchards (0.042 1) > Nurseries of young forest (0.040 8) > Mountain shrub forest (0.034 2). The correlation analysis on soil erodibility and soil physical and chemical properties showed that the soil erodibility K value was closely related to the factors such as silt content, clay content, noncapillary porosity, soil water storage capacity and bulk density correlation (P < 0.05), which can be used as evaluation indices of soil erodibility.
