中文摘要对金沙江流域水土流失,河道泥沙及主要影响因素系统作了分析,认为地质,地貌及因子是影响水土流失的主要因素,人为活动加剧水土流失的发生发展。河道泥沙主要来自金沙江下游,特别是下游干流河谷区间,流域的地面侵蚀与河道泥沙的空间关系不密切,影响输沙量的主要因素为年径流量和清水区年径流量,以及滑坡,泥石流等重力侵蚀,尽管水土流失治理对于流域的河道泥沙减沙效应显著,但短期内对流域干支流输沙理的影响甚微。
英文摘要Based on the analysis of major inf luence element s of the surface erosion and fluvial silt
in the Jinsha River Watershed, the authors confirm that the condit ions of g eology , landform and climate are the major factors effcet ing the surface erosion, and the injudicious social economic activities intensified the occurrence and development of soil and waterloss. The fluvial silt is chiefly produced in the lower reaches of the River, especially in the main river valley of the low er reaches. The surface erosion of the watershed is not closely related to the flvial silt in space, the major elements w hich in fluence the amount of w ater-borne silt are the runoff volume in the w atershed and
in the clear w ater are of the w atershed. Although the effect of the control of soil and water loss is bremarkable in the reduction of f luvial silt in small w arershed, yet is scarcely in fluences the amount of  water-borne silt in the mainst ream and tributaries of the River. The fluvial silt of Jinsha River Watershed w ill not be notably reduced in short times.
