长江上游流域地表侵蚀与河流泥沙输移

Surface Erosion in Upper Yangtze Region and River Sediment Transport

在丰富的野外考察、调查及实测资料基础上，将长江上游流域地表侵蚀与河流输沙作为一个完整系统，综合分析了地表物质的侵蚀～堆积～归槽～输移过程，探讨了流域产沙特性及泥沙运动规律。

On the basis of large amount of field investigation and measured data , taking both the sur-face erosion in the upper Yangtze region and the transport of Sediment in the river as a whole system,a comprehensive analysis is made for such processes as erosion , accumulation and transportation. Andthe characteristics of sediment yielding out of this region and the law of sediment motion are discussed.
