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 4万km2 ,年土壤侵蚀量为 114 95万t ,年土壤侵蚀模数为 10 0 0～ 80 0 0t/km2 。有效防治水土流失 ,加快生态环境建设的对策和途径是 ,把水土保持作为生态环境建设的主体工程 ,坚持走综合治理的成功之路 。Being the sources of the Yangtze River, Yellow River and Lanchang River, Qinghai province is featured with severe water, wind and frozen erosion, which often happen in complex patterns. There are totally 334 thousand km 2 of soil and water loss area with annual soil erosion of 114 950 thousand tons, and with soil erosion modulus of 1 000 to 8 000 t/km 2. In order to effectively prevent soil and water loss, the corresponding treatments and methods for accelerating ecological environmental construction are to take soil and water conservation as the main project of ecological environmental construction, to insist on the successful way of comprehensive management, to persist the simultaneous development of ecological benefit with economic benefit, and so on.
