Abstract:: The ecetone between agriculture and animal husbandry in northern region of Yinshan Mountains is an important line of the ecosystem constructing in the north of China. Recently, due to the sharply increasing of population, economic poverty and absurd land using, land degenerated speedy and eroded severity. The main character of the study area is the coexistence of wind erosion and water erosion. The maximum wind erosion modulus is 9 985 t/ (km²·a), the maximum water erosion modulus is 3 000 t/ (km²·a), the composite erosion amount is very large, the percentage of soil and water loss area is 89.8%. According to this situation, this paper described the process of land erodesion, analyzed the reasons of nature factor and man-made factor, discovered that coupling existed between the two factors in time and space, exposed the law of interaction, mutual promotion and cooperative aggravation between the two factors, provided ideas for the soil erosion harness in this area.
