Kuerbin, a Manchu word, means "fish farm" in Chinese, hence the name of Benhe. Formerly known as the keerfen River, it is the famous emerging hydropower Industrial Base in Xunke county. There is a large Kuerbin hydropower station in the upstream. Most of the river basin is Xunke county. Part of the riverside flows through Tangwanghe Forestry Bureau, covering an area of 31204 hectares. The upstream of the basin is Xiaoxing'anling forest region, and the downstream is Xunke farm agricultural region.

Main stream situation

Kurbin river originates at the north foot of Xiaoxing'an Mountains, 1.5km east of Qichang, Yichun Youhao Forestry Bureau

Class 522 of Xinfeng Forest Farm (in Xunke County, 1,28 ° 52 ′ e, 48 ° 53 ′ n)

）It flows through the forest area of Shangganling for 41 kilometers, with an average width of 55 meters, an average flow of 35 cubic meters per second and a minimum flow of 0.5 cubic meters per second. The river was closed in the middle and late November, opened in the middle of April the next year, and finished at the end of April.

Kurbin river flows northward from its source through five forest farms in Wuyiling Forestry Bureau, namely, Kelin, Qianjin, Xinsheng, atin River and kungfu. The drainage area of kurbin river is 1127 square kilometers, accounting for 33% of the total area of the whole, with a flow of 272 million cubic meters. From the Kelin estuary to the atting estuary, it is 74 km long and 30-50 m wide. It is a constant flow river. The water system in the territory is composed of seven major rivers, including Korbin River, atin River, the first, second, third and fourth tributaries of atin River, and Kelin River, all of which are located on the north slope of Xiaoxing'an Mountains.

In Xunke County, it flows through five townships including Kelin, Daping, Baoshan, Xinxing and Chelu, and flows into Heilongjiang near Limin Village of Chelu township. The estuary is 4 km to the east of Xunhe river.

hydrographic features

According to the survey report of Korbin River in 1977 by Xunke County Water Conservancy Bureau, the average annual precipitation in this basin is about 560-600mm. The distribution rule is that the precipitation from June to September accounts for about 70% of the whole year. Due to the influence of the Pacific monsoon and Siberian high, the summer is extremely hot and rainy, and the temperature can reach more than 36 ℃. It is very cold and snowy in winter, and the lowest temperature is about - 44 ℃. The average temperature for many years is about - 9 ℃. The ice sealing period lasts about 170 days from the end of October to the middle of April of the next year. The thickness of the ice layer is more than 1.4 meters, and the maximum frozen soil layer can reach 2.2 meters. The maximum flow was on August 8, 1961, the average daily flow was 2 280 m3 / s, and the highest water level on the same day was 92.45 M. The minimum low flow was on June 12, 1962, and the average daily flow was only 4.55 m3 / s. There is too much iron in the kurbin river.

The atin river basin covers an area of 723 square kilometers with a flow of 159 million cubic meters.

Kelin River, a tributary of Korbin River, originates at the foot of tekeshe mountain (Erlong mountain), 129 ° 12 ′ E and 48 ° 51 ′ n, flows through Kelin Management Office in Tangwanghe district and then enters Korbin river. This river is the boundary between Tangwanghe Forestry Bureau and Xunke County, with a total length of 28 km (26 km)

）。 The river is 9 meters wide, with a drainage area of 404 square kilometers and a flow of 56 million cubic meters. It is a Changliu river.

Huoji River, with a total length of 18 km, originates from 1 km to the east of xiaojushan, 39 forest class, Yangguang forest farm. The upstream part is about 10 km in the shiye district (Xunke county administrative district) of Tangwanghe Forestry Bureau, covering an area of 44 square kilometers.

It flows into the kurbin River on the right side of the upper reaches of the kurbin river. The river is 5 meters wide and 0.3 meters deep, with a drainage area of 7142 hectares.

General situation of River Basin

Kuerbin river basin is high in the South and low in the north. The elevation of the high mountain (Bailu mountain) near the source of the river is 795 meters. At the confluence of the estuary and Heilongjiang, the elevation is only about 100 meters, showing the great drop. Above the large platform reclamation area, the river valley is open, the river is serpentine, and there are many swamps on both sides. The whole basin is densely forested, with good vegetation, narrow channel and many good dam sites. The river bed has large drop and less sediment. The runoff supply is good and the flow is fast. There are few villages and farmland on both sides of the Strait. This area is suitable for cascade development and is an excellent base for hydropower generation. The first hydropower station in Xunke County, Korbin hydropower station, was built in the middle reaches of the river. It is one of the backbone power stations in rural electrification pilot counties. Four hydropower stations have been built along the river, including Korbin, Baoshan, Baishi and Wuyi.

As a result of power generation, the hot water discharged reaches 4 degrees above zero. The clear and bottoming river of Korbin river is not frozen all the year round, and the high temperature of minus 20 degrees in winter produces beautiful and spectacular rime. From late November to early March of the next year, the banks of the river, which is more than 20 kilometers long downstream of the power station, are covered with silver and crystal clear. Agate is rich in the middle reaches of the coast, which is an important producing area of agate. Due to the unique volcanic landform, Rhododendron sea and kurbin rime on both sides of the river, the government turned it into a Geopark, namely Hongxing volcanic rock Geopark, which was officially approved as a provincial Geopark in October 2008. Hongxing volcanic rock Geopark has unique geomorphic features, long geological history and biological diversity. At the same time, Kuerbin River and Kuerbin reservoir are in Hongxing Wetland National Nature Reserve, which is a good place for tourism.

Governance and development

Kurbin hydropower station is located in the upper reaches of kurbin River, 60 km away from Wuyiling station, the terminal station of Harbin Urumqi railway, and 150 km away from Qike town. The drainage area above the dam site is about 2300 square kilometers, the total storage capacity is about 390 million cubic meters, the average annual flow is 15 cubic meters per second, and the average annual water volume is nearly 500 million cubic meters. The project is composed of main dam, auxiliary dam, spillway, water pipe and powerhouse behind dam. The dam type is rockfill dam with residual oil core wall for seepage control. The maximum dam height is 23.5m and the maximum dam length is 418m. There are 3 installed units (1600 kW each), with a total installed capacity of 4800 kW and an annual generating capacity of 13.6 million kwh. The project design is undertaken by the Northeast survey and Design Institute of the Ministry of hydropower. With the approval of Heilongjiang Electric Power Bureau, the project was started in 1977. By July 1, 1984, the unit 1 was put into operation for power generation. The total amount of works is 198600 cubic meters, including 20100 cubic meters of concrete, and the completed investment is 13.75 million yuan. In 1985, 127 kilometers of high-voltage transmission lines from Baoshan Township to Qike town were reconstructed, with an investment of 1 million yuan. By July 1, the three units were put into operation at the same time to send power to the whole county. When the water level is normal, the design requirements can be achieved.

The large platform flood control project was designed by the County Water Conservancy Bureau, started in 1983 and completed in 1984. It is divided into Tianshan Mountain, Pingshan mountain and Qianshan Mountain. 22 main drainage channels (59.25 km), 118 branch channels (139.05 km), and 2 intercepting ditches were completed,
