The Yellow River basin in Qinghai covers an area of 152，300 square kilometers，the length of the main stream accounts for 31% of the total length of the Yellow River，and the average annual outflow of water accounts for 49.4% of the total flow of the Yellow River. It is not only the source area，but also the main stream area，which has a decisive influence on the sustainable development and utilization of water resources in the Yellow River basin.
