The Media Group of the Fifth "Voice of Shaanxi, Via Which We Communicate
with the World" Visited Dongzhuang Water Control Project

On the afternoon of July 29, the media group of the fifth "Voice of Shaanxi, Via Which We Communicate with the World" theme publicity campaign came to Shaanxi Dongzhuang Water Control Project Construction Co., Ltd. (hereinafter referred to as "Dongzhuang Water Control Project") to gain an in-depth understanding of the company's practice on ecological protection and high-quality development of the Yellow River Basin.

According to Xiao Hongwu, Party Secretary and Chairman of Shaanxi Dongzhuang Water Control Project Construction Co., Ltd., the dam site of Dongzhuang Water Control Project is located at the end of the canyon in the lower reaches of Jinghe River, which is the only "Pivot" project for ecological protection and high-quality development of the Yellow River Basin under construction in China. Of the total storage capacity of 3.276 billion cubic meters in the project, 2 billion cubic meters are used to block sand. As an important project in the Yellow River water and sediment regulation engineering system, this project is the only water control project with a large sediment retention capacity on Jinghe River, and it is also a water control project for water and sediment regulation on the river with the highest sediment concentration in the world.

The sediment discharge of Jinghe River accounts for 20% of the Tongguan section of the Yellow River, which is one of the main sources of sediment in the Yellow River. According to the prediction results of the mathematical model, Dongzhuang Water Control Project can reduce about 2.5 billion tons of sediment entering the Yellow River and 1 billion tons of sediment deposition in the lower reaches of the Yellow River after being put into operation for 50 years, indicating remarkable effects of sediment reduction. Besides, by flood retention, peak reduction and peak alternation, the flood control standard in the lower reaches of Jinghe River has been raised from blocking once-in-a-decade flood to once-in-two-decades flood, and the flood in the lower reaches of Weihe River has been reduced from once every 100 years to once every 50 years.

After Dongzhuang Water Control Project is completed and put into use, it can effectively improve the ecological impact of insufficient ecological flow and cut-off, and play an important role in improving the river ecological environment during fish breeding and the downstream river ecological environment in flood season. At the same time, the water surface of the reservoir area with a length of more than 90 kilometers will be formed in the arid tableland of Weibei, which will play a significant role in increasing the regional water surface, regulating the regional microclimate, and improving the ecological environment of the reservoir area. In addition, according to the plan, a scenic leisure area will be constructed with Dongzhuang Dam Hub and the water surface of the reservoir area as the core, which is also of great significance for improving the living environment and the life quality of the people in Guanzhong area.
