黄河上游河流矢量图

黄河是我国第二长河，黄河泥沙问题引起全世界人民的关注。本数据根据全国1:400万河流矢量图为底图，利用黄河上游流域边界裁剪而成。河流矢量图是利用地形图提取流域边界的一个关键要素，同时也是做洪水演进和泥沙演进的关键要素。 本图以ArcGIS,.shp文件存储，包括自黄河源区到头道拐的干流和支流...

The Yellow River is the second-longest river in China, and its sediment-related issues have attracted widespread global attention. This dataset is obtained by cropping the national 1:4,000,000 scale river vector map (taken as the base map) using the boundary of the upper Yellow River basin. River vector maps serve as a key element for extracting basin boundaries from topographic maps, and are also critical for flood routing and sediment routing studies. This dataset is stored in ArcGIS-compatible .shp format, covering the main stem and tributaries from the source region of the Yellow River to Toudaoguai...
