The Yellow River Basin

<p>With the implementation of relevant policies on pollution control, the water environment of the Yellow River basin has been improved during recent years. However, for the river basin management agency, there remains an urgent need for gaining better knowledge of the changing patterns of water quality throughout the basin in order to get early warnings of water quality deterioration and make decisions on water allocation schemes. In this study, we collected water quality data including 24 routine monitoring parameters during 2014-2019 from over 100 monitoring stations located along the Yellow River. After assessing the water quality grade for each section according to the Environmental Quality Standards for Surface Water in China, we identified the key parameters that affect the water quality condition of the basin. The spatial and temporal variations of the key water quality parameters, in particular the relationships with driving factors which include natural factors (i.e., precipitation, temperature and evaporation) as well as anthropogenic factors (i.e., land cover and land use, pollution emission, population and social economy), were presented by conducting correlation analysis. Furthermore, based on the characteristics of the water quality time series and the significances of the driving factors to water quality, we built several data-driven models to predict the water quality condition at a monthly scale for the Yellow River basin, such as seasonal autoregressive model (SAR), multivariate linear regression (MLR) and artificial neural network (ANN), while the performances of those models were evaluated. This study provides critical information for understanding the response relationship between water quality and its related factors for a typical river basin, thus facilitating the dynamic assessment of water resources.</p>

New Situation

Yellow River is an important source of water for northwest and north China, and an important strategic guarantee for the sustainable economic and social development of the Yellow River basin and its related regions. The Yellow River water allocation scheme (Scheme 1987 in short) was approved in 1987 by the State Council, which was the first river water allocation scheme in China. It allocates a total volume of 58 billion m3 of water to the 11 provinces along the river and its ecosystem. However, with the deepening impact of climate change and human activities, the Yellow River water resource and its development situations have some changes and the water resource of the drainage basin faces new situations, so it is urgent to carry out the optimization and adjustment study of Scheme 1987 under the new situation. The background and promulgation process of Scheme 1987 was reviewed comprehensively, and its implementation effect for 30 years was analyzed from two periods before and after unified dispatching. The new situation of the development of the Yellow River basin in the future was analyzed, and the work to be carried out to optimize and adjust the Scheme 1987 was prospected.
