History of construction

As early as 6000 years ago, human beings lived and multiplied in the area where Datong Lake District is located. In the early Ming Dynasty, it was a fertile land.

In 1860 (the tenth year of Xianfeng in the Qing Dynasty) and 1873 (the twelfth year of Tongzhi in the Qing Dynasty), the dikes in the south of Jingjiang River were washed open at ouchikou and songzikou respectively by the river water, and the river water went down to the south, inundating a large number of ancient dikes and hilly plains. This place became a part of the waters of Dongting Lake. The Yangtze River carries a large amount of sediment to Dongting Lake through Ouchi River, Songzi, Taiping and tiaoxian, which makes the water surface of Dongting Lake shrink rapidly. Guangxu years, is Changde Anxiang county.

In 1913, after the establishment of Nanxian County, the dykes and marshes along the Datong Lake were subordinate to Nanxian County, Yuanjiang County, Xiangyin County, Huarong County and Yueyang County.

In 1949, all the embankments along the lake burst.

In March 1950, Datong Lake flood storage and Reclamation Management Office was established, which is under the Provincial Department of agriculture and forestry. The former provincial orphanage is located in the house compound of anrenyuan, and the former orphanage is engaged in the reclamation of 10000 mu of public property wasteland in 3000gong (now Anfu village, Hekou township). At the same time, the provincial people's government promulgated the regulations on the administration of flood storage and reclamation area of Datong Lake, which stipulates that "the boundary of Datong Lake extends to Yongkang embankment and Tai'an embankment in Nanxian County in the west, yemaozui in Xiangyin in the East, baosanhuan and Pufeng embankment in Yuanjiang City in the south, Tianhe embankment and Fuhe barrier one line five embankment in Nanxian County in the north, with a total area of 327 square kilometers, or 490000 mu; the wasteland of tuhu Lake in jiuyuanzhou is about 140 square kilometers The total area is about 467 square kilometers, or 700000 mu. " "All the land in Datong Lake area belongs to state farms, and it is allowed to be temporarily recruited for reclamation when it is unable to directly manage all the land."

In January 1951, the Preparatory Office of Datong Lake farm was established. The people's Government of Datong Lake special administrative region was established in April of this year to work with the flood storage and reclamation administration office.

In January 1952, Datong Lake farm was upgraded to form a trinity of government, affairs and enterprises with the SAR government and management office, directly under the leadership of the provincial people's government. That year, the provincial public security department went to zengfuhuan (today's Jinpen town) and planted minheyuan (today's qianshanhong town) to set up reform through labor farms.

In June 1953, the Hunan Provincial Committee of the Communist Party of China decided to establish the Datong Lake farm at the sub prefecture (Department) level.

In 1956, Datong Lake farm was changed into county (Department) system.

In the winter of 1957, with the approval of the CPC Hunan Provincial Committee, Datong Lake Farm surrounded beizhouzi.

In 1958, beizhouzi branch was set up (changed to 11th and 12th branch in 1962). In the winter of that year, the provincial public security department withdrew the reform through labor farms from zhongfuyuan and zengfuhuan. Zhongfu embankment (Minhe embankment) was managed by Yuanjiang County. Qianshanhong people's commune was established, which was immediately renamed "local state-owned qianshanhong farm", and lihou and Lizhen embankments under the jurisdiction of Hekou township of Nanxian county were also included. Zengfu, Youcheng, Yucheng, Shanyan and Yuanjiang counties belong to Qingcheng Township, which is directly under the central government of Nanxian county. They are immediately incorporated into Datong Lake farm, with 7, 8 and 9 branches.

In 1959, Datong Lake farm was changed to a sub county (Department) level and was managed by Nanxian county.

In 1961, Datong Lake farm was restored to provincial management. In that year, Liu Shan, deputy commander of the 47th army of the Chinese people's Liberation Army, and his party held a letter of introduction from the Hunan provincial Party committee of the Communist Party of China to negotiate with the Datong Lake farm about the land allocation. The farm agreed to assign the nungu Lake (now Nanwan Lake) to the army.

In November 1962, with the approval of Hunan Provincial Committee of the Communist Party of China, Datong Lake farm was divided into Datong Lake farm, beizhouzi farm and Jinpen farm. The 11th and 12th branches of the former Datong Lake farm are assigned to beizhouzi farm, and the zengfuhuan, Nanjing lake, youchengyuan, yuchengyuan and Sijihong of the former Datong Lake farm are assigned to Jinpen farm. In that year, qianshanhong farm in Yuanjiang County was changed to be under the management of the Provincial Bureau of agricultural reclamation, and was renamed the state-owned qianshanhong farm, which was a county (Department) level system.

At the beginning of April 1963, a large number of farmers in Huage commune of Nanxian County went to beizhouzi farm to make hay as fertilizer for early rice fields, and had disputes and fights with the management of the farm. On April 22, representatives of Nanxian county and beizhouzi farm signed an agreement to transfer the water surface of rudder bar Island, xinluzhou, Changzhou and other Huzhou to Huage commune of Nanxian County for free. Beizhouzi farm is still managed by the farm within 500 meters of the East dike of the farm. Later, Nanxian county and Yuanjiang County divided the Huzhou water surface transferred by beizhouzi farm, with beidaohe River as the boundary, Yuanjiang County in the South and Nanxian County in the north.

In 1965, Sijihong was assigned to Yuanjiang County to resettle Zhexi reservoir immigrants in Anhua County.

In November 1969, the Provincial Bureau of land reclamation was abolished. In January of the following year, the farms of Datonghu, beizhouzi, Jinpen and qianshanhong were transferred to Yiyang District, and the farms were downgraded to the sub county level, which was under the jurisdiction of Yiyang District Farm Management Bureau.

In 1978, the Hunan Provincial Farm Management Bureau was established, and the former provincial farms were changed to regional management, and the provincial and local management.

In February 1986, the original provincial state farms were restored to the county level.

In October 2000, Datong Lake Management area was officially established.

geographical environment

Location context

Datong Lake District is located in the north of central Hunan and the hinterland of Dongting. It is adjacent to gouhu Lake in the East, Yuanjiang City in the south, Nanxian county and Huarong County in the northwest. It is between 112 ° 15 ′ 28 ″ - 112 ° 42 ′ 02 ″ E and 29 ° 01 ′ 19 ″ - 29 ° 19 ′ 16 ″ n, with a total area of 384 square kilometers.

Geology and geomorphology

The terrain of Datong Lake area is a typical alluvial plain of Dongting Lake. Lakes, water surface and ditches crisscross in the area. The parent material of soil formation is river and lake sediments, with low-lying and flat terrain, and the surface elevation is between 24-32 meters.

Climatic characteristics

Datong Lake area is a continental monsoon humid climate zone with the transition from the middle subtropical zone to the north subtropical zone. Because it is located in Hunan Province, surrounded by mountains on three sides and on the north entrance of horseshoe shaped landform, it is easy for cold waves to invade and stay in the south. However, due to its low latitude and Lake Plain, it has a mild climate, abundant heat, abundant rainfall and four distinct seasons, which has the general characteristics of subtropical monsoon humid climate zone. The regional microclimate is relatively stable in summer and autumn due to the influence of lake surface climate in Dongting Lake and Datong Lake.
