摘　　要：The ecological environment in the area where the Qinghai-Tibet Railway passes through is very fragile and is showing the tendency of retrogression. So as the construction would largely disturb the earth surface and vegetation and would have a large quantity of earth and stone digging, the construction of the railway in this area would certainly lead to a series of questions. Through the integrated analysis of the actualities of soil erosion and water and soil conservation along the section of Tanggula-Lhasa of the Qinghai-Tibet Railway, and with the combination of the features of the railway construction and the environment, the protection measures and proposals about the soil erosion along the section of Tanggula to Lhasa of the Qinghai-Tibet Railway have been put forward, so as to reach to the purpose of holding back the further development of soil erosion along the line, improving the ecological environment in the local area and maintaining the railway in normal operation.The ecological environment in the area where the Qinghai-Tibet Railway passes through is very fragile and is showing the tendency of retrogression.
