摘要: 长江南源当曲源头为高原沼泽,通行不便。在长江三源之中历来少有人涉足,其基本情况及其对江源水系的作用亦少为外界所知,河流演变及水沙运动特性的研究甚少。为了对长江南源当曲源头的河道、水流、泥沙等基本特性及当曲源头典型地貌特征进行了解,长江科学院继2014年后于2015年再次组织了科学考察。通过考察对当曲源头水沙特性进行了初步分析,分析成果为高原河流演变及河岸带生态系统提供了基础资料,同时对其它河流治理及河流生态保护与修复具有参考价值。

Abstract: Dangqu River, the south source of Yangtze River, is less studied by researchers due to plateau swamp and poor transportation. The basic characteristics of flow and sediment and its impact on water system of river source are little known to the outside world, with few research results of river evolution and transportation characteristics of flow and sediment. In order to obtain fundamental behaviors such as waterways, flow and sediment of Dangqu, as well as typical landform, researchers in Yangtze River Scientific Research Institute organized scientific investigation for Dangqu River again in 2015. The previous scientific investigation was done in 2014. The investigation results can be used as basic data for river evolution and ecosystem at river bank in plateau, and can be referenced for the harnessing, ecological protection and restoration of other rivers.

Key words: source of Yangtze River, Dangqu River, river system in source region, scientific investigation, river sediment, characteristics of water and sediment
