- Abstract
The Yellow River is the mother river of the Chinese nation, and its change of water resources has an important impact on the social and economic development of the Yellow River basin and even the whole country. The water shortage situation is the biggest challenge for the current and future of the Yellow River. In this study, based on the observed runoff data of the four typical hydrological stations of the Yellow River, namely Lanzhou, Toudaoguai, Huayuankou and Lijin from 1950 to 2017, the annual runoff variation characteristics of the Yellow River mainstream flow were analyzed. Affected by climate change and human activities, the annual runoff of the hydrological stations in the mainstream of the Yellow River showed a significant downward trend and the rate of decline showed a cumulative effect. In the 1960s, the Yellow River had the largest runoff in the past 100 years and the runoff significantly decreased after the 1990s. Runoff for the four hydrological stations showed change point in 1985/1986. The annual runoff in change period was significantly lower than the annual runoff in the base period, and the decline was increasing from upstream to downstream. Results of the observed runoff analysis only reflect that the Yellow River runoff change is the result of the combined effects of climate change and human activities(including land use). How to distinguish their impact ratio is a scientific issue that needs further study. To build Beautiful China, the Yellow River is indispensable. It is proposed to promote the coordinated development of water-ecological-economic cooperation in the basin, to sort out the complex relationship between water-ecological-economic sustainable development and water-energy-food in the Yellow River basin and to develop collaborative development program of water resources utilization, ecological protection and economic development in the Yellow River basin as soon as possible.
