The lake water system of Hulun Lake, what lake does Hulun Lake belong to?

The Hulun Lake system consists of Hulun Lake, Halaha River, Bear Lake, Wuersun River, Krulun River, Xinkai Lake and the Dharan Oromu River, which connects Hulun Lake and Erguna River.

Krulun River, historically, Krulun River was once called Gonglu River, Yuqu River, Yinma River, Timid Green River, Qing Dynasty to the present, called Krulun River. "Krulun" is translated as "Guangrun" in Mongolian, and the name of the river is named after its change of meaning "to carry forward". The Krulun River originates at the eastern foot of Kent Mountain in the Republic of Mongolia, enters China from west to east near the Zoshunul Temple, and flows eastward through the towns of Adun Lusumu and Alatan Emol into Hulun Lake.

The total length is 1264 kilometers, and it is about a kilometer long in China. The banks of the Krulun River are surrounded by semi-desert hills and hills, the river valley is about 3000 meters to 5000 meters wide, the river surface is generally 40 meters to 90 meters wide, the river channel is relatively curved, there are more river beaches, wetlands and swamps, because the basin is mostly semi-desert terrain, the surface runoff is not developed, so there are fewer tributaries. The water depth is about 2 meters, with the largest flow in summer and autumn, and there are swamp wetlands on both banks, and the aquatic grass conditions are good, which is an excellent natural pasture.

The Wuersun River, which originates on the north shore of Lake Bear Lake and flows north into Hulun Lake, is 223 kilometers long. The upper reaches are the Halaha River of the Erguna River system, which is located at the junction of the New Balhu Right Banner and the New Balhu Left Banner in Hulunbuir City. The terrain on both sides of the river is flat, and the width of the river is 60-70 meters.

The floodplain is overgrown with reeds and willows, and there are many wetlands. Animal husbandry on both sides of the river is well developed.

Dharan Oromu River Xinkai River: Located in the northeast of Hulun Lake, the river is 25 kilometers long, and its flow direction is restricted by the changes of Hulun Lake and Hailar River.

What lake does the Haraha River flow into?

Hulun Lake is a freshwater lake. Hulun Lake, also known as Hulun Lake, Dalai Lake, Dalai Nuoer, and Bear Lake are sister lakes to each other. In Mongolian, it means "lake like the sea".

History has been called Daze, Julunbo, Kuolian Haizi, Hutuze, Xuanliao Pond, Kuleng Lake and so on. It is the main birthplace of many nomadic peoples in the north, and the Donghu, Xiongnu, Xianbei, Murwei, Hui, Turkic, Khitan, Jurchen, Mongolian and other ethnic groups have multiplied here.

Hulun Lake is located in the hinterland of the Hulunbuir Grassland, known as the "Pearl of the Grassland" and "the Kidney of the Grassland", which has a special status in the protection of the regional ecological environment and plays a very important role in maintaining the biodiversity of the Hulunbuir Grassland and enriching the animal and plant resources. Hulun Lake has been inhabited by humans since prehistoric times. The Northern Qi Dynasty was called Daze, the Tang Dynasty was called Kulunbo, the Liao and Jin Dynasty were called Kuolian Haizi, the Ming Dynasty was called Kuoluan Haizi, the Qing Dynasty was called Kulenghu, and the local herdsmen were called Dalai Nuoer.

Hulun Lake is a name that only exists in modern times, and "Hulun" is a homonym of the Mongolian word "Hayu", which means "otter"; "Bell" means "male otter" in Mongolian. In ancient times, these two lakes were rich in otters, and the Mongolians who lived near the lakes named the two lakes after the ancient custom of naming mountains, rivers, lakes and springs after animals and plants.

Due to the drought and other reasons, the water level of the lake has continued to decline in recent years, and the water surface has decreased by about 300 square kilometers, resulting in the shrinkage of wetlands and the degradation of the ecological environment of the lake area. From 2000 to 2009, the water level of Hulun Lake has dropped by about a meter, with an average of 50 centimeters per year! The water area of Hulun Lake has shrunk by 477 square kilometers, which is 20 square kilometers smaller than the historical maximum area of 2,339 square kilometers; The water storage capacity of the corresponding lake is less than 7 billion cubic meters, which is half of the historical maximum storage capacity of 100 million cubic meters.

According to relevant data, the pH value of the lake water has risen from the 60s of the last century to the current one, the alkalinity has risen from milligrams of milligram equivalent per liter to the salt content has risen from thousandths to thousandths, and the alkalized lake water has made three species of fish extinct, they are the fine-scale fish, the Mongolian red ghost and the serosaurus.

In October 1992, a national nature reserve was established in Hulun Lake. Hulun Lake National Nature Reserve covers an area of 740,000 hectares and is located in China at the junction of China, Mongolia and Russia, and is part of the transnational ecosystem.

In 2006, the Inner Mongolia Autonomous Region implemented the Hulun Lake Water Resources Allocation and Water Environment Treatment Project, diverted water from the Hailar River, replenished the water volume of Hulun Lake, restored the wetlands in the lake area, and effectively curbed the deterioration of the ecological environment.

Since 1999, the Inner Mongolia Meteorological Bureau has used satellite remote sensing to monitor the water body of Hulun Lake for 11 consecutive years, and this year Hulun Lake opened about 5 days later than last year. The monitoring shows that the area of Hulun Lake has been shrinking in the past 11 years, and is now less than 1,800 square kilometers, and the area has shrunk by about 620 square kilometers. The water environment of Hulun Lake has also deteriorated year by year, and the water level observed this year is meters, which is lower than the same period last year, and the transparency is 28 centimeters, which is 1 centimeter lower than the same period last year.
