| 中文摘要 | 金沙江下游侵蚀强烈,输沙模数达2060t/(km2*a),为金沙江流域和长江上游平均侵蚀模数500t/(km2*a)的4倍,并且近年还在增长.其原因主要有:河流沿断裂发育,岩层破碎;金沙江下游是袭夺河,侵蚀力强;滑坡、泥石流发育,侵蚀量大;干旱严重,植被一旦破坏,恢复困难;光热资源丰富,人为干扰强烈. |
| 英文摘要 | The erosion is very strong in the lower reaches of the Jinsha River. The modulus of sediment delivery is 2 060 t / ( km2·a ) , that is 4 times as big as 500 t / ( km2·a ), which is modulus of sediment delivery in the basin of the Jinsha River and upper reaches of the yangtze River. The main formations of strong erosion in the lower reaches of the Jinsha River are following: The river develops along the faults. The rocks are broke along faults; The lower reaches of the Jinsha River is a captured river, the longitudinal gradient of river bed is steep; The debris flow and landslide develops extensively and erodestrongly; The climate is very dry, and the vegetation recovery is difficult after its breakdown; The light and hot resources are very rich. But the man disturb environment strongly. |
