| 摘 要： | 青海省是长江、黄河、澜沧江的发源地,水蚀、风蚀和冻融侵蚀都较严重并呈复合型出现.全省水土流失面积为33.4×104km2,年土壤侵蚀量为115×108t,年土壤侵蚀模数为1000～8000t·km-2.公路建设中对水土保持造成危害虽然面积相对不大,但其破坏强度较大,极难治理和恢复.公路建设中坚持"预防为主,防治结合,因地制宜,因害设防"的工作方针,明确防治重点,科学的进行防治分区、措施布局和措施设计,准确计算工程量和工程投资,合理安排水土保持措施实施进度,制定出切实可行的水土保持实施措施.

| Abstract: | Qinghai Province is the source area of the Yangtze River, the Yellow River and the Lancang River. Recently, environmental destruction frequently occurs, such as water erosion, wind erosion, frost and thaw. The soil erosion area in the province t is 334×103 km2, and the annual eroded soil is 114.95×106 tons, with an annual eroded soil modulus of 1000～8000 t·km-2. In the construction of highway in the province, problems with soil erosion is not very large in area, but the damage degree is very high and difficult to manage and repair. The following policies must insist on construction of highway: prevention as the main, combined with maintenance, in a manner appropriate to local conditions, and aiming at aid diseases. The key prevention must be definite, prevention zoning, measures allocation and design must be scientifically made, engineering extent and investment must be truly calculated, program of soil and water conservation must be logically managed, and then convenient strategy for soil and water conservation must be established. |
