Historical evolution

On January 1, 1956, with the approval of the State Council, the Ministry of agriculture and reclamation, the CPC Hubei Provincial Committee and the provincial government, the state-owned Longganhu machinery farm was established under the jurisdiction of the Department of agriculture and reclamation of Hubei Province and the Huanggang administrative office. In September 1957, the name of the farm was changed to Longganhu farm. In January 1959, it was put under the jurisdiction of Huangmei County, named Longganhu people's commune of Huangmei County. In March 1960, the CPC Hubei Provincial Committee decided to restore the organizational system of Longganhu farm, which is still under the Hubei Provincial Department of land reclamation. In December 1966, the farm changed its name to the workers, peasants and soldiers Farm. In January 1969, the name of Longganhu farm was restored. in 1971, the farms in Hubei Province were organized by the state as the agricultural reclamation production and Construction Corps of Hubei Province, Wuhan military region of the Chinese people's Liberation Army, and Longganhu farm was its subordinate independent regiment. The organizational system and seal remained unchanged. in December 1972, BINGTUAN was abolished, and the farm was renamed Longganhu farm, which was subordinate to the Bureau of agricultural reclamation of Hubei Province (renamed from the Department of agricultural reclamation of Hubei Province, and renamed as the agricultural, industrial and Commercial General Corporation of Hubei state farm in 1983). since January 1, 1992, the farm plan has been listed separately (the statistics were listed separately in 2006), ending the history that the farm plan was included in Huangmei County. on September 1, 1996, Huanggang Longgan Lake Management Zone was established. There are two brands and one team in the management area and farm. On October 9, 2001, the opinions on the reform of provincial farms issued by the CPC Hubei Provincial Committee and the Hubei Provincial People's government made it clear that "Longganhu farm is managed by Huanggang City". "In principle, it is agreed to set up a management area as the agency of the municipal government to manage the economic and social affairs within the area.". "After the reform of the management system, the organizational system of the farm will remain unchanged, and one organization, two brands and one team will be implemented with the management area.".

The sub field has 68 agricultural production teams. The place where the farm organ is located is called "general farm". after the establishment of the management area, there are eight offices in the management area, namely luchai lake, Yanghu lake, Shahu Lake, Chungang lake, Saihu lake, qingni lake, yanjiazha and Chengguan.

The management area relocated the qingnihu office and implemented the management of flood storage and discharge. In September 2000, the qingnihu office was abolished, a new district (farm) Agricultural Science Institute was established in qingnihu Dawu, and the former agricultural science institute in Shahu office was abolished.

On February 11, 2001, Leichi office was merged into yanjiazha office, and the number of production teams under each office was adjusted from 68 to 46. In March 2003, Shahu office re zoned the Xiasha team, Shiwei team and comprehensive team which were merged into Daqiao new village, xiangxinwei team and Gaoping team in 2001, and restored them to three production teams according to their original names.

geology

Longgan Lake, which is adjacent to Longgan Lake Management area, was a land in ancient times. In the fourth century, it sank to form a water area, which was called Peng Lize in ancient times and intersected with the old road of the Yangtze River. Due to the long-term deposition of the Yangtze river alluvium, the lake bottom was gradually raised, resulting in the shrinkage of ancient penglize. Later, when the rivers and lakes separated and the Yangtze River moved southward, the name of ancient Peng Lize disappeared and was replaced by "Leishui" and "Leichi". Later, with the deposition of lake sediments and the flood alluvial deposits of the Yangtze River, "Lei Shui" further shrank, forming Taibai lake, ganhu lake, Daguan lake, Huanghu lake, Bohu lake and other lakes (Longhu Lake and ganhu lake are collectively called Longgan Lake). The strata in the area are composed of Yangtze river alluvium, lake sediments and river lake mixed sediments, belonging to Quaternary Holocene (Q4) geology.

At the end of 2007, the original 11 Lakes (Yanghu, Saihu, luchai, Jinhu, Shahu, Chaihu, Banjiu, Yangliu, Baimao, Tiane and qingni) were all named as true or false.
