China is rich in water resources, how to make full use of resources and rely on water conservancy projects to play an active role has become a key area of concern. At the construction site of a major national water conservancy project, the Pearl River Delta Water Resources Allocation Project, dozens of domestic large-scale shield machines are accelerating their excavation. "At present, the construction of the project is more than halfway through, and more than 10 sections of water delivery tunnels have been connected, and strive to achieve early water supply by the end of 2023." Du Canyang, the person in charge of the project construction, introduced that the total investment of the project is 35.399 billion yuan, and the designed annual water supply volume is 1.708 billion cubic meters, which will effectively guarantee Water demand in the Guangdong-Hong Kong-Macao Greater Bay Area.

One after another dams stretch across the rivers, pipelines climb the mountains, and reservoirs cover the mountains and hold water... A number of basic, pivotal, and strategic major water conservancy projects have been erected, and the construction of the national water network has been accelerated. According to data from the Ministry of Water Resources, the construction of 150 major water conservancy projects is accelerating. By the end of 2021, 67 projects have been approved and 62 projects have started. Up to now, the investment scale of major water conservancy projects under construction in China has exceeded one trillion yuan.

A major water conservancy project, protecting the river and Anlan. In the upper reaches of the Huai River, the river is wide and horizontal, and the dam stands tall. Recently, the Chushandian Reservoir in Xinyang City, Henan Province passed the completion acceptance. "The flood control storage capacity of the reservoir is 691 million cubic meters, which can ensure the safety of 2.2 million mu of land downstream of the reservoir and the safety of 1.7 million people." Zhu Yunxian, director of the Chushandian Reservoir Construction Management Bureau, introduced.

The construction of a number of major water conservancy projects focusing on flood control has been accelerated, and the flood control engineering system of damming, storage, drainage and discharge has been continuously improved. Projects such as reservoir groups, flood control levees, and flood storage and detention areas have significantly improved the overall flood control capacity of China's river basins.

A major water conservancy project has provided more means to restore the ecology of rivers and lakes. After the implementation of 150 major water conservancy projects, it is expected that the length of the river can be controlled about 2,950 kilometers, and the annual water supply capacity will be increased by about 42 billion cubic meters.

A major water conservancy project has strengthened the support of food security. In Hubei, the Qishui Irrigation Area, one of the 150 major water conservancy projects, can irrigate more than 380,000 mu of fertile fields; in Guizhou, after the Jiayan Water Control Project is completed, it will supply water to about 900,000 mu of arable land in the water-receiving area.

At present, China has built the world's largest and most extensive water conservancy infrastructure system with the largest number of beneficiaries. The Ministry of Water Resources proposed that this year, a major national water network project will be implemented to enhance China's overall water resources allocation capacity, water supply guarantee capacity, and strategic reserve capacity.
