Beijing MDI Birthmark Research Institute Celebrates The Completion Of Guanting Reservoir 60Th Anniversary

< p > Beijing medi birthmark Research Institute celebrates the completion of Guanting Reservoir 60th anniversary. Guanting reservoir is located in Zhangjiakou city of Hebei province and Yanqing County of Beijing city. It started construction in October 1951 and completed in May 1954. It is the first large a href= http:// sjfzxm.com/news/index_s.asp > reservoir < /a > built after the founding of new China.

< p > < strong > Guanting Reservoir: the first large reservoir after the founding of the people's Republic of China < /strong > /p >

< p > Guanting reservoir is the first large reservoir on the Yongding River in Haihe River system of China.

In Huailai County, Hebei, China, it is 105 kilometers away from Beijing.

The Yongding river is one of the main streams of the Haihe River system. Most of it flows through the loess area, with a large amount of sediment (up to 32.2%). It is known as "little the Yellow River".

The lower reaches are silted up and the riverbed rises.

In order to eradication the Yongding River, the Guanting reservoir was built in October 1951 and completed in May 5, 1954.

< p > reservoir was built at the entrance of Guanting gorge.

It is said that there is a "water officer" in the Ming Dynasty to monitor the water regime.

The old Guanting village was named after the Guanting hall.

The installed capacity of the power station is 30 thousand kilowatts, built in 1955, and the power supply for Ping Jin.

Guanting reservoir was once one of the main sources of water supply in Beijing.

< p > < strong > the function of Guanting reservoir is < /strong > /p >

< p > Guanting reservoir has been running for more than forty years, and has played a huge role of < a href= "http://sjfzxm.com/news/index_s.asp" > flood control > /a > benefit.

< /p >

< p > < strong > (1) flood control benefit: < /strong > < /p >

< p > the reservoir flood control benefit is remarkable, basically eliminating the flood disaster in the lower reaches of the Yongding river.

After the completion of the reservoir, eight floods were more than 1000 cubic meters per second, and the flood peak discharge was reduced by 70~96%, which played a role in flood control and storage, so that no flood disaster occurred downstream. It played a very significant role in ensuring flood control safety in the vast areas of the lower reaches of Beijing, Tianjin, Hebei and Yongding river.

< /p >

< p > < strong > (2) the largest flood of historical experience: < /strong > /p >

From the end of July 1959 to the beginning of August, there was an instantaneous flow of 2660 cubic meters per second in the upper reaches of Guanting reservoir, with a peak of 2499 cubic meters per second in storage. P

In order to ensure the safety of the reservoir, the water conveyance tunnel and the power generation diversion tunnel are mainly used to regulate the reservoir. 79 gates are opened, 178 million cubic meters are released, and the maximum discharge is 600 cubic meters / second.

At the same time, in the case of large flood in the Guanting gorge, in order to lighten the burden of the lower river channel, the drainage channel discharge has been properly adjusted in time, and the reservoir has made an attempt at the wrong peak.

< p > < strong > (3) water supply benefit: < /strong > < /p >

As of 2000, the reservoir accumulated 39 billion 800 million cubic meters of water to the lower reaches, including 8 billion 400 million cubic meters of agricultural water for Beijing, Tianjin and Hebei, 1 million 380 thousand mu of irrigation area, 17 billion 300 million cubic meters of industrial water in Beijing, 2 billion 500 million cubic meters of underground water supply and living environment water.

It has played an important role in promoting the development of capital industry and agriculture and improving the environment of the capital city.

< p > < strong > (4) power generation efficiency: < /strong > < /p >

The construction of Guanting reservoir has created conditions for cascade power generation in Guanting County, P.

Following the completion of the Guanting hydroelectric power station in 1956, two cascade hydropower stations, namely the lower Maling and the lower reed, have been built successively. By 2000, three generating stations were generating 8 billion 200 million degrees, providing a large amount of electricity for the capital and North China, and alleviating the tension of peak power consumption.

< p > < strong > (5) comprehensive operation benefit: < /strong > < /p >

< p > reservoir managers, on the basis of ensuring the safe operation of the reservoir, have made full use of the advantages of water and soil resources before and after carrying out projects such as afforestation, planting fruit trees, developing aquaculture and catering services. In the past fifty years, 158 hectares of greening barren hills and 1 million 200 thousand kilograms of fruit have been produced. The new variety introduced by the forest industry technicians, Chun jujube, has become a major product of the reservoir because of its thin, fragrant, sweet and crisp fruit.

The grain harvest is about 1 million 500 thousand kilograms and a large number of agricultural and sideline products. The whole reservoir catches 17 million kilograms of fresh fish.

Each year, it can be supplied to the market < a href= "http://sjfzxm.com/news/index_s.asp" > supply > /a > turtle 2000 kg, fruit 20 thousand kg.

< /p >

< p > Guanting reservoir plays a great role in water supply, power generation and flood control. At the same time, because of the various fruits with abundant sugar and convenient pportation in the nearby sandy land, it is really a good place for everyone to relax around.
