Core Viewpoint - The "Yin-Da Ji-Huang" project, the largest inter-basin water diversion project in the upper reaches of the Yellow River, has supplied 185 million cubic meters of water in its first six months of operation, demonstrating significant benefits for irrigation and ecological restoration [1][2]. Group 1 - The project has provided 76 million cubic meters of ecological water replenishment, benefiting the main stream of the Huangshui River [1]. - The Huangshui River basin, which accounts for 65% of Qinghai's population and 71% of its arable land, faces a severe water resource mismatch, with only 3.4% of the province's water resources available [1]. - The total investment in the project is 14.634 billion RMB, with an annual water supply capacity of 526 million cubic meters and a controlled irrigation area of 1,004,900 acres [1]. Group 2 - The project supports irrigation for one million acres of agriculture and forestry, as well as two industrial clusters worth over 100 billion RMB each, benefiting approximately 3 million people [2]. - Advanced technologies such as digitalization, networking, and intelligence have been integrated into the project, creating a modern water management model characterized by precise scheduling and comprehensive perception [2].

Core Viewpoint - The article highlights the severe drought conditions in the Huai River basin and the proactive measures taken by the Anhui provincial water conservancy department to ensure water supply for urban residents and agricultural irrigation through major water diversion projects. Group 1: Water Diversion Projects - The Yangtze River water diversion project has played a crucial role in combating drought, with the East Fei River section being a key node where water is pumped and diverted into the Huai River. Since the opening of the East Fei Gate on July 18, approximately 1.89 billion cubic meters of water have been diverted over 12 days [2]. - The Huai Water North Diversion Project, an extension of the Yangtze River diversion project, has also been significant in providing water. As of July 31, 2023, it has supplied 17.61 million cubic meters of water to Suzhou and Huai Bei, with a total of 59.99 million cubic meters supplied this year [3]. Group 2: Regional Drought Impact - The city of Huainan has experienced a drastic reduction in rainfall, with only 17 mm recorded in July, a decrease of 80%-90% compared to the same period in previous years. The city has relied on the first phase of the Yangtze River diversion project for approximately 1.89 billion cubic meters of water to support agriculture [4]. - In Fuyang, the average rainfall has been only 14 mm since late June, down over 90% from the norm. The city has intensified its drought response, extracting over 200 million cubic meters of water since late June, a threefold increase compared to previous years [4]. - The Cihua New River irrigation area has also been active, with the management bureau operating the pumping station for 58 days, extracting 3.81 billion cubic meters of water to meet urban and agricultural irrigation needs [4].

Core Points - The "Yin Da Ji Huang" project, a major inter-basin water diversion project in Qinghai, has been fully completed and operational after 29 years of construction, significantly improving water resource distribution in the region [10][11] - The project benefits over 3 million people, transforming 1 million acres of dry land into irrigated land, thus changing the agricultural landscape and reducing reliance on natural rainfall [10][11] - The project faced numerous challenges, including complex geological conditions, extreme weather, and high equipment failure rates during winter construction, which were successfully overcome by the construction teams [10][11] Agricultural Support - The completion of the North Canal Phase II has led to a successful harvest of highland cool vegetables in the Taizi Township of Huzhu County, demonstrating the project's positive impact on local agriculture [5] Industrial Support - The "Yin Da Ji Huang" project provides essential water resources for the zero-carbon industrial park located in Haidong City, supporting industrial development in the region [7] Ecological Conservation - The diversion of water through the main canal has increased the water volume in the Beichuan River, enhancing the ecological environment and turning the Beichuan River Wetland Park into a new cultural tourism landmark [9]
