金沙江流域的河流泥沙输移特性

金沙江是长江上游河流泥沙的主要来源。通过对金沙江流域主要控制水文站径流泥沙资料的统计分析。该文论述了金沙江河流泥沙的来源和沿程分配、输水得的年内分配和年际变化、径流量和输水利一的关系以及泥沙形成的原因。为研究金沙江流域的水土流失和泥沙输移规律，合理地开发和利用其水土资源提供了科学依据。

Characteristics of Sediment Transportation in Jinsha River Basin

The Jinsha River is a main sediment source of the upper Yangtze River.Through statistical analysis of water and sediment data at major hydrologic stations in the Jinsha River basin, this paper presents the sediment transport characteristics of the basin including the sediment sources and distribution, the annual variation and annual distribution of sediment load, the relationship between runoff and sediment load, and the genesis of sediment. It provides a scientific basis for researching the rule of soil eorsion and sediment transportation, and investigating reasonable development and utilization of soil and water resources in the Jingsha River basin.
