Through overall discussing the effect of forest management practices such as harvesting, site preparing, soil preparing, tending and agroforestry managing, it indicated that any forest management praotire influencing on land covering and soil properties can increase soil erosion.Further the more the management practice disturbed the forest land, the more soil erosion was, this is especially obvious on the area that erosion durability of soil was low and rainfall erosivity high. Improper cut and site preparation may increase soil erosion; If site preparing,tending,agroforestry management were inappropriately employed, erosion may increase sharply，young stand soil thus may directly affect the long-term maintenance of stand fertility.In order to attain soil and water conservation and maintenance of stand long-term productivity, the overall study on effect of traditional forest management practices on forest ecosystem should be strengthen and the disturbance intensity of management practices on stand be decreased to the full.
