金沙江流域产沙区和泥沙输移特性分析

Characteristic Analysis on Sedimentation Formation Are and Sedimentation Transport in Jinshajiang Basin

本文根据金沙江流域干、支流主要控制站泥沙和径流资料，分析了该流域重点产沙区和泥沙输移特性后得出;该流域泥沙流失严重，特别是1982年后，由于人类活动影响，致使泥沙以12.2％的速度增加，应引起有关部门重视，并采取有效的治理措施。

Based on sedimentation and runoff data from main control stations on main Jinshajiang River and lts tributories,characteristics of main sedimentation formation area and sedimentation transport in the basin are analyzed. It is concluded that the loss of sedimentation in the area is great. Especially after 1982,frequent human activities lead to sedimentation increase by 12. 2%. This problem should be paid attention by concerned departments. Measures should be taken effectively.
