%X A preliminary study on the characteristics of soil and water losses on slopes land use forvarious purposes has been made based on the data obtained from the Anxi experimental sta-tion. The results show that the soil and water losses can be gradually controlled as long asthe slopes have a certain vegetation cover combined with appropriate slope interceptiveworks,though some soil and water losses may occur at the beginning period. Because the dis-turbed soil has a weak resistance to erosion, the coverage of cultivated land should be in-creased,especially in summer. It is suggested that the C value should be 0.1-0. 3 on undis-turbed natural bare slopes when USLE is adopted to predict the soil erosion.The contour terrace has a sound function of soil and water conservation,but it has somelimits such as expensive labour cost and inconvenint transportation. Based on the measureddata,the Vetiveria belts and grass cover have the similar function of soil and water conserva-tion to contour terrace on slope. The model of the Vetiveria belts interplanting with fruitsand annual leguminous crops combined with hill side ditch can be extended on steep slope.The pattern of fruit garden with grass cover combined with hill side ditch can be spread inthe coastal areas where have a good economic condition.
