Danjiang Reservoir is the largest artificial lake in Asia. Although its water area is only half that of Taihu Lake, its water storage capacity is six times that of Taihu Lake, mainly because its water depth exceeds 100 meter. Danjiang Reservoir is the water source of the Middle Route of South-to-North Water Transfer Project, from which most of the urban water in Beijing and all the water in Tianjin come.
Danjiang Reservoir was formed after the Danjiangkou Dam built by 1973 was impounded. It consists of Hanjiang reservoir area and Danjiang reservoir area. Located in the upper reaches of the Han River between danjiangkou city, Hubei Province and Xichuan County, Nanyang City, Henan Province, the dam is a large-scale water control project with multiple functions such as irrigation, power generation, shipping, flood control and aquaculture.
Characteristics of Danjiang Reservoir
Danjiang Reservoir is located at the junction of Jianghan Plain and Qinba Mountain area, with mild climate and four distinct seasons. The ecological environment around the reservoir area is beautiful and rich in water resources, and it is known as "Tianchi in Asia". The water quality of the reservoir is excellent, reaching the national first-class standard of surface water, and it is an important wetland reserve in China. The reservoir area is rich in aquatic animal and plant resources and biodiversity.
In recent years, the importance of Danjiang Reservoir has become increasingly prominent. As the water source of the Middle Route of South-to-North Water Transfer Project, it shoulders the important mission of alleviating the shortage of water resources in northern China and improving the ecological environment. In addition, Danjiang Reservoir is also a national first-class water source protection zone and a national ecological civilization demonstration zone, which plays an important role in ensuring water resources security and ecological balance.
In order to protect this precious water resource, our government has taken a series of measures. For example, strengthen environmental protection and governance in the reservoir area, strictly control pollutant emissions, and ensure stable water quality; Implement ecological restoration projects to improve the ecological environment of the reservoir area; Strengthen the management of water resources, rationally allocate water resources and ensure the sustainable utilization of reservoirs.
