News from this station At 10:00 on April 28, the control gate of the South Canal of the Sinv Temple Hub in Dezhou, Shandong was opened. The water of Yuecheng Reservoir merged with the water of the North Extension Project of the East Line of the South-to-North Water Diversion Project and the Yellow River Diversion through the Wei Canal, and entered the South Canal. The South Canal Control Gate of Jiuxuanzha Hub in Jinghai District, Tianjin was opened, and the water from the south merged with the local water in Tianjin via the South Canal; before that, the water from the North Canal merged with the local water in Tianjin and merged with the water from the South Canal at the mouth of the Sancha River in Tianjin; , the Beijing-Hangzhou Grand Canal runs through the entire water flow.
The Beijing-Hangzhou Grand Canal has a long history, vast projects and extensive benefits. It is a living heritage. However, affected by historical evolution, human activities and climate change, the northern section of the Yellow River of the Beijing-Hangzhou Grand Canal is in serious shortage of water resources, and problems such as water ecological damage and water environment pollution are still very prominent. General Secretary Xi Jinping made important speeches and instructions on the governance of groundwater overexploitation in North China, the recovery of the ecological environment of rivers and lakes, and the protection, inheritance and utilization of the Grand Canal. The east route of the South-to-North Water Diversion Project has become a lifeline for optimizing the allocation of water resources, ensuring the safety of drinking water for the masses, revitalizing the ecological environment of rivers and lakes, and smoothing the economic cycle between the north and the south. In order to give full play to the comprehensive benefits of the South-to-North Water Diversion Project, promote the comprehensive control of groundwater over-exploitation in North China and the recovery of the ecological environment of rivers and lakes, improve the resource conditions of the water system of the Grand Canal, and restore the vitality of the Grand Canal. After careful study by the party group of the Ministry of Water Resources, the Ministry of Water Resources, together with the people’s governments of Beijing, Tianjin, Hebei and Shandong provinces and cities, officially launched the water replenishment action of the Beijing-Hangzhou Grand Canal in 2022.
The water supply of the Beijing-Hangzhou Grand Canal will be replenished to the 707 kilometers north of the Yellow River in the Beijing-Hangzhou Grand Canal by optimizing and dispatching water sources such as water supply, yellow water, local water, reclaimed water and rain and flood water for the east route of the South-to-North Water Diversion Project. 515 million cubic meters. It involves four provinces and cities including Beijing, Tianjin, Hebei and Shandong, 8 prefecture-level administrative regions, and 41 counties with overexploitation of groundwater. It is expected to achieve three goals: First, reduce the exploitation of groundwater. Water was diverted from the Grand Canal, and farmland irrigation was carried out in an orderly manner, replacing groundwater irrigation water of about 600,000 mu of arable land in Jinghai District, Binhai New District, Hebei, Cangzhou, Hengshui and other cities in Hebei. The second is to replenish groundwater. The water supply sources supply water to the Zhang River, Wenyu River, Qiyi River and other rivers along the way. The total length of the water supply channels reaches 1,230 kilometers (including 707 kilometers north of the Yellow River in the Beijing-Hangzhou Grand Canal). The groundwater level around the river has recovered or remained stable. Third, the Beijing-Hangzhou Grand Canal runs through the entire water flow. Compared with the same period in 2021, the length of the rivers north of the Yellow River in the Beijing-Hangzhou Grand Canal has increased by about 112 kilometers, and the water surface area has increased by about 9.5 square kilometers. The main sections of the canal basically have water targets to accumulate experience.
As of April 27, a total of 263.62 million cubic meters of water had been supplied to the northern reaches of the Yellow River in the Beijing-Hangzhou Grand Canal, completing 51% of the planned water supply. Among them, Miyun Reservoir accumulatively replenished 24.49 million cubic meters of water, Yuecheng Reservoir accumulatively replenished 62.49 million cubic meters, East Line North Extension Project accumulatively replenished 75.8 million cubic meters, and Panzhuang Yellow River Diversion Project accumulatively replenished 23.29 million cubic meters. Give full play to the water supply function of the canal, and provide irrigation and ecological water along the line. Tianjin City has led out a total of 22.21 million cubic meters for irrigation of 48,000 mu of farmland; Hebei Province has led out a total of 20.44 million cubic meters, of which 14.5 million cubic meters are used for 102,000 cubic meters. 5.94 million cubic meters of farmland are irrigated for ecological replenishment of Hengshui Lake.
