News from this website (Reporter Hao Rubing, North New News, North Net) controls the watershed area of 5,364 square kilometers, and raises the flood control standard of the Yimin River from once in 30 years to once in 100 years, protecting the lives and property of people on both sides of the middle and lower reaches of the river. And 212,000 mu of grasslands are protected from flood disasters... On July 22, the reporter walked into the only large-scale water conservancy project in my country's alpine regions - Honghua'erji Water Conservancy Project. This is the "pillar" of flood control in Hulunbuir area. Ballast stone for safe flight.
The mountains are high and the water is wide, the blue waves are rippling, and the water birds are flocking... In the Honghuaerji Water Conservancy Project, the ecological picture scroll of "green water and lush mountains are invaluable assets" is slowly unfolding.
Honghuaerji Water Conservancy Project and water supply project are a combination of water conservancy and ecology. Taking Honghuaerji Water Conservancy Project as the fulcrum, a water supply project is built to support the construction of the pipeline. The total length of the pipeline is about 108 kilometers, starting from Honghuaerji Reservoir and ending in Heihua. The Yangzhan Water Plant ensures the continuous delivery of mountain spring water in the forest to the homes of nearly 400,000 residents in the central urban area of Hulunbuir and Ewenki Banner, and at the same time, delivers industrial water to Yimin Power Plant.
At present, about 25 million cubic meters of urban water supply and about 10 million cubic meters of industrial water supply are provided every year, reducing the dependence and extraction of groundwater for regional economic development, conserving grasslands, and attracting a variety of waterbirds to settle in the reservoir area.
The reporter learned that Honghuaerji Hydropower Branch adopts a combination of drone inspections and artificial water surface inspections, and joint law enforcement between enterprises and local law enforcement departments to strengthen daily inspections of first-class protected areas of water sources, and strictly prevent pollution and damage to water. The occurrence of environmental and other events has continued to consolidate and improve the quality of the water environment in the reservoir area, and the water quality has been stably maintained above the national third-class standard for surface water for a long time.
At the same time, the company regularly inspects and maintains the 23 hydrological monitoring stations located in the 5,364 square kilometers of the controlled watershed above the dam site, and according to the weather and rain information in a timely manner, scientifically and reasonably arranges the operation mode of the hydro-generator units, and adjusts the storage capacity to prevent floods and floods. , to improve the level of dam safety management and control.
"This is the only large-scale water conservancy project in the alpine region in China. The melting of heavy snow can easily cause spring floods. In order to ensure the normal communication of the site's hydrological monitoring site and the accuracy of flood forecasting, we will regularly repair and maintain the 24 upstream hydropower sites. Most of the sites are built in the deep mountains and old forests of the Daxinganling Mountains, which is very inconvenient to pass. We often need to carry more than 50 kilograms of circuit boards and walk for more than 4 hours to reach the top of the mountain." Chen Lei, the operation and maintenance duty officer of Honghuaerji Hydropower Branch, told me Reporter, the staff regularly goes to the upstream to observe the situation of Kaihe River every year. The daily trip is more than 200 kilometers. It takes 5 days for an overall inspection. The staff establishes close contact with the upstream residents, herdsmen and the staff of the fire checkpoint to keep abreast of spring floods. dynamic and ensure the safety of the dam.
