黄河“八七”分水方案实施30 a回顾与展望.

The paper reviewed the historical background, research process and continuous development of the Yellow River water allocation scheme in 1987 (Scheme 1987 in short), and analyzed the implement processes and effects of the two periods before and after the integrated water regulation in 1999. The new challenges and solutions of the water resources under changing environment in the basin were proposed. Scheme 1987 is the first basin-scale water allocation scheme for large rivers in China. It has great breakthroughs and demonstration significance for China to promote the scientific allocation and efficient use of water resources. Scheme 1987 has been continuously refined, deepened, developed and improved by series of work such as refinement among tributaries and regions, improvement of the water allocation scheme under the new runoff conditions and the formulation of the red line for water consumption control, which strongly supports the water resources management of the Yellow River basin and constitutes an important watershed management technical documentation. In the past 30 years, Scheme 1987 and the Yellow River water resources management practice have effectively restrained the water demand growth of the basin, coordinated the water use relations of the 11 provinces and regions along the river, supported the sustainable socioeconomic development of the basin and the maintenance of the ecological environment, and realized the mainstream continuous flowing for 20 consecutive years. In the future, the demand for water resources in the Yellow River basin will continue to show a certain rigid growth. The key issue of water resources management in the basin is how to alleviate the constraints of water resources on socioeconomic development of the basin, and support the benign maintenance of the ecological environment.
