History of Huangnichuan Reservoir

The historical evolution of Baihebao Reservoir Baihebao Reservoir Irrigation District was built in 1976 and completed in 1990. There are four main water conveyance channels in the irrigation area, with a total length of 92 12km and a total irrigation area of 324,000 mu. Among them, the south main canal is 53.75 kilometers long and the irrigation area is 240,000 mu. The north main canal is 24.64 kilometers, with an irrigation area of 84,000 mu. The water supply canal of the Ming Tombs is 6.33 kilometers, and that of Guanting Reservoir is 7.4 kilometers. Main buildings of main canal: 73 sluices; 7 tunnels with total length of1551m; There are 24 aqueducts with a total length of 4957 meters. Every year, 300-400 million cubic meters of irrigation water is provided to Sichuan District of Yanqing County, and 65438+200 million cubic meters of water is replenished to Guanting Reservoir and Ming Tombs Reservoir.

Irrigation area * * * plans to build 82 branch canals, and control the irrigation area of 2 1 10,000 mu; Build 47 pumping stations and control the irrigation area of 92,000 mu; The mobile pumping station controls the irrigation area of 22,000 mu. 55 branch canals were operated, and 8 pumping stations were built, with an irrigation area of 654.38+0.79 million mu. Since 1996, the main canal has been reconstructed, and 65 branch sluices (closed sluices) have been reconstructed, with the length of the main canal being 34 kilometers. And the effective utilization of irrigation water is ensured.

In the Ming Dynasty, there was a fortress called Jing 'an Fort, which guarded the Baihe Canyon, so it was called Baihe Fort. The average temperature in summer is 20 degrees Celsius. It is the fifth largest reservoir and the highest reservoir in Beijing.

The reservoir will lead the Baihe River to the front of the mountain through a 7090-meter water tunnel, which will supply water for the economic and social development of Yanqing Sichuan, and at the same time supply water to Guanting Reservoir and Ming Tombs Reservoir. It is an important water conservancy hub that connects Guanting and Miyun river systems across river basins and allocates water resources. In 2002, Baihebao Reservoir replenished 59.99 million cubic meters of water for Guanting and Ming Tombs Reservoir. The county's water consumption is 65.438+0.24 billion cubic meters, of which: agricultural water supply is 65.438+0./kloc-0.20 billion cubic meters, industrial water supply is 3.5 million cubic meters, and urban domestic water supply is 8.37 million cubic meters. Since the establishment of the reservoir, * * * has replenished 654.38+07 billion cubic meters of water to Guanting Reservoir; Replenish 300 million cubic meters of water to the Ming Tombs Reservoir; Power generation 1 100 million kwh; Provide 370 million cubic meters of water for agricultural irrigation in Yanqing. Due to years of drought, Beijing has become a city with serious water shortage in the world. Yanqing, located in the upper reaches of Beijing, is an important water source in Beijing. In order to ensure the normal domestic water consumption of Beijing residents, Baihebao Reservoir has undertaken the important task of delivering water to Miyun Reservoir since 2003. As of June, 2007, * * * delivered water to Miyun Reservoir 10 times, with a cumulative water delivery of 483 million cubic meters.

With the decrease of rainfall year by year, the inflow of small and medium-sized reservoirs in Baihebao Reservoir is less than expected. Due to years of drought, the groundwater level is declining.

In order to better protect the water quality in the upper reaches of the reservoir, water source protection and greening projects have been implemented in the upper reaches of the reservoir. Since the establishment of the reservoir, more than 200,000 trees have been planted. In 2004, the dam crest was reinforced in view of mechanical failure and circuit aging of electromechanical equipment; The spillway gate, electrical equipment and computer room have been repaired and reformed; The gate of the regulating pool has been updated; In 2005, the spillway tunnel was repaired and rebuilt; It improves the flood storage capacity of the reservoir and is conducive to ensuring the flood control safety of the reservoir. In 2005, together with Chicheng County, Hebei Province, the Baihebao Reservoir water source protection project was built, and the soil erosion control area was 25.03 square kilometers.

In the future, reservoir management will be strengthened, operation equipment will be updated, and water source protection will be done well to make it play a better role.

The history and culture of Qingtongxia-108 Tower Qingtongxia is located on the cliff on the west side of Qingtongxia Reservoir in Ningxia. There is a huge tower group, with a total of 108 towers, commonly known as108 towers.

According to research, 108 pagoda was built in Xixia. Whenever the weather is sunny, the towers are reflected on the sparkling lake, and the scenery is strange, elegant and bright.

One hundred and eight towers sit west to east, with mountains and water at their backs. From top to bottom, the mountains are strewn at random and orderly, with many pagodas 1, 3, 3, 5, 5, 7 and 9.

A large tower group with odd numbers arranged in an equilateral triangle. The overall layout of the tower group is unique and unique. According to folklore, 108 Pagoda is Mu's "pointing platform" and "Tianmen array", in fact, it is a Buddhist memorial tower.
