Information about Dongting Lake

Dongting Lake, formerly known as Yunmeng, Jiujiang and Chonghu, is located on the south bank of Jingjiang River in the middle reaches of the Yangtze River, crossing Yueyang, Miluo, Xiangyin, Wangcheng, Yiyang, Yuanjiang, Hanshou, Changde, Jinshi, Anxiang and Nanxian counties and cities. The name of Dongting Lake began in the Spring and Autumn Period and the Warring States Period, and it was named after Dongting Mountain (now Junshan Mountain) in the lake.

Dongting Lake receives water from Songzi, Taiping, Ouchi and Diaoxian of the Yangtze River, and connects with the four small tributaries of Hunan, Zi, Yuan and Li in the south and west, and flows into the Yangtze River from Chenglingji, Yueyang City.

Dongting Lake used to be called "eight hundred Li Dongting Lake" in ancient times. At the end of 199s, it was estimated by the water conservancy department that there was an area of 2,579.2 square kilometers (2,74 square kilometers). However, it also has a spillway area of more than 1,3 square kilometers (18,78 square kilometers) in the four rivers of Hunan, Zi, Yuan and Li and the "four mouths of the Yangtze River". Together, there are still 3879.2 square kilometers. The circumference of the lake basin is 83.2 kilometers, with a total volume of 22 billion cubic meters, including 17.8 billion cubic meters of natural lakes and 4.2 billion cubic meters of rivers.

Dongting Lake is an important storage lake in the Yangtze River basin, with strong flood storage capacity. It has saved countless floods in the Yangtze River, and Jianghan Plain and three towns in Wuhan have been able to survive the flood safely.

Dongting Lake is an important strategic place in history and the birthplace of traditional culture in China. There are many scenic spots in the lake area, and the historic site represented by Yueyang Tower is an important tourism cultural resource. It is also the birthplace of traditional Chinese agriculture, a famous land of plenty, and the most important commodity grain and oil base, aquatic product and breeding base in Hunan Province and even the whole country.

Dongting Lake area is located in the south of the middle reaches of the Yangtze River and in the north of Hunan Province. Dongting Lake, with Dongting Lake as the core, is a dish-shaped basin, which transits from the east, south and west to the alluvial plain of rivers and lakes, hilly land around lakes and low mountains. In terms of administrative divisions, it includes 1 counties of Yueyang, Huarong, Xiangyin, Nanxian, Anxiang, Hanshou, Lixian, Linli, Taoyuan and Wangcheng, and 4 county-level cities of Linxiang, Yuanjiang, Miluo and Tianjin.

Yueyang Louqu, Junshan District and Yunxi District in Yueyang City, Ziyang District and Heshan District in Yiyang City, and Wuling District and Dingcheng District in Changde City, covering 21 counties and cities, in addition to Songzi, Gongan and Shishou counties and cities in Hubei Province. Part of Hunan's land area is 31,7 square kilometers, accounting for 15% of the province's area.

Dongting Lake area is a "land of plenty" in Hunan and even the whole country. The surrounding areas are extremely rich in natural resources, with a solid agricultural production base and a large number of laborers. It is of great significance to establish the economic circle around Dongting Lake to accelerate the economic and social development of Dongting Lake and even Hunan.

on the premise of emphasizing economic benefits and adhering to environmental benefits, we can establish a national super-large commodity grain base, a commodity pig base, a commodity aquatic product base, a high-level foreign exchange earning agricultural base and an ecological agricultural base; Establish high-level, high-level tourist bases, scientific, technological, cultural and educational bases and commercial bases to realize the sustainable economic and social development of the lake area.

During the pre-Qin and Han Dynasties, Dongting Lake was also called Jiujiang, which merged the flood diversion flows of Hunan, Zi, Yuan, Li and Jingjiang and flowed northward into the Yangtze River. At that time, the river could reach the lower reaches of Lishui River and cross Jiujiang River, that is, it was diverted through Dongting Lake, while the terrain from the south bank of Jingjiang River to the lower reaches of Lishui River was high in the north and low in the south (which is just the opposite of the present situation).

because the Yangtze river basin and sishui river basin in the upper reaches of Jingjiang River are sparsely populated, the degree of development is low, the original forest is still well preserved, and the soil erosion is extremely slight. Therefore, although Dongting Lake accepts the flood of sishui River and Jingjiang River, there is little sediment entering the lake and the water flow is clear.
