The origin of Hulun Lake, and how big is the area of Hulun Lake?

2339 square kilometers.

Hulun Lake, also known as Hulun Lake, Dalai Lake, Dalai Nuoer, and Bear Lake are sister lakes to each other. History has been called Daze, Julunbo, Kuolian Haizi, Hutuze, Xuanliao Pond, Kuleng Lake and so on. Hulun Lake is located in the western part of the Hulunbuir grassland in the Inner Mongolia Autonomous Region, between the new Balhu Right Banner, the new Balhu Left Banner and the Zhainuoer District, it is an irregular oblique rectangle, the long axis is southwest to northeast, the lake is 93 kilometers long, the maximum width is 41 kilometers, the average width is 32 kilometers, the lake circumference is 447 kilometers, the area is 2339 square kilometers, the maximum water depth is 8 meters, the average water depth is meters, and the water storage capacity is 100 million cubic meters.

Hulun Lake is the largest lake in Inner Mongolia, the largest lake in Northeast China, the fifth largest lake in China, the fourth largest freshwater lake, and the largest freshwater lake in the arid region of central Asia.

Located in the Hulunbuir grassland of Inner Mongolia, Hulun Lake once had a maximum area of 2,339 square kilometers, an average water depth of 10 meters, and a water storage capacity of 13.85 billion cubic meters. In the past seven years, due to natural and man-made damage and other factors, the water replenishment of Hulun Lake has decreased year by year, the water area has shrunk by 440 square kilometers, the water level has dropped by 2 66 meters, and the water storage has decreased by 4.55 billion cubic meters, down by 6 and 32 85 respectively. Due to the serious impact on the ecological environment of Hulun Lake, the water quality has deteriorated, and the precious fish in the lake, such as the fine-scale fish, Mongolian red fish, and Zheluo, have been extinct one after another.

In view of the grim situation, the relevant departments of Inner Mongolia will effectively increase the water supply and water level of Hulun Lake through the implementation of water diversion projects; Strictly control the amount of fishing, resolutely crack down on illegal fishing and overfishing, so that Hulun Lake can recuperate. At the same time, it is planned to raise funds through multiple channels to increase the ecological governance of the surrounding areas of Hulun Lake and ensure the sustainable development of the ecology of Hulun Lake.

Hulun Lake, also known as Dalai Lake, is located in the Hulunbuir grassland of Inner Mongolia, with a historical maximum area of 2,339 square kilometers, an average water depth of 10 meters, and a water storage capacity of 13,850 million cubic meters.

Hulun Lake is 800 miles in circumference, with thousands of blue waves, like a crystal pearl, inlaid on the Hulunbuir grassland. Hulun Lake, also known as Lunchi Lake and Dalai Lake, is one of the four major freshwater lakes in China and the largest lake in Inner Mongolia. It is the birthplace of the Kruren River and the Ulsun River.

The lake covers an area of 2,339 square kilometres, with an average depth of meters, a maximum depth of about 8 meters, and a storage capacity of 13,850 million cubic meters.

The area of Hulun Lake is: 2339 km.

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 was called Kuolian Haizi, the Ming Dynasty was called Kuoluan Haizi, the Qing Dynasty was called Kulen Lake, and the local herdsmen called Dalai Nuoer (Mongolian, meaning "lake like the sea").

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.

With tectonic movements and climate change, its scope has expanded and contracted more than once in history. When the lake shrinks, it becomes a wetland and a discontinuous small lake; When the lake expands, it becomes an outflow of the lake. In most of the period, Hulun Lake was an outflow freshwater lake, and the lake water flowed into the Ergun River, which flowed into the Heilongjiang River.

The pH value is. The change of water quality of Hulun Lake also depends mainly on the increase or decrease of the water volume of the lake: when the water volume of the lake increases, the water level rises, and it becomes a drainage lake, and the salt content decreases, which is a freshwater lake; When the water volume of the lake continues to decrease, the water level continues to drop, it only swallows but does not spit out, and even cuts off the connection with the outflow river and becomes an inland lake, at this time, the salt content of the lake water increases, and even becomes a brackish water lake.

The surface area of Hulun Lake has increased to square kilometers.

Hulun Lake, located in the northeast of Inner Mongolia, west of the Great Xing'an Mountains, the western part of the Hulunbuir Grassland, most of which is in the territory of the New Balhu Right Banner of Hulunbuir City, is the largest lake in northern China, with an irregular oblique rectangle. Hulun Lake covers an area of 2,339 square kilometers, with an average water depth of about 8 meters, the deepest of about 8 meters, and a water storage capacity of 100 million cubic meters.

In ancient times, Hulun Lake had a variety of names, such as Daze, Kulunbo, Luluanluo, Kuolian Haizi, Kuoluan Haizi, Kuleng Lake, etc., and the local people called Dalai Lake (Mongolian), which means a lake like the sea.

Hulun Lake and Bear Lake are a pair of pearls on the Hulunbuir steppe, and many of the northern nomads who lived in this area in history have multiplied in this area, such as Donghu, Xiongnu, Xianbei, Murwei, Hui, Turkic, Khitan, Jurchen, Mongolian, etc. During the Three Kingdoms, Xianbei people, a branch of the Xianbei people, gradually migrated south from here, and finally established the Northern Wei Dynasty when the Central Plains were in turmoil after the fall of the Western Jin Dynasty to unify the north.

Hulun Lake belongs to the Erguna River system, and its water supply mainly comes from the Krulun River and the Wuersun River. The Krulun River originates in Mongolia, and the Ursun River is a river that connects Lake Hulun and Lake Bear. Bear Lake receives water from rivers such as the Halaha River at the western foot of the Great Khing'an Mountains, and then flows into Hulun Lake through the Wuersun River.

Hulun Lake covers an area of 2,339 square kilometers. Hulun Lake is also known as Hulun Pond, Dacha Yulai Lake, Dalai Nuoer, Mongolian means "sea-like lake". Hulun Lake is located in the western part of the Hulunbuir grassland in the Inner Mongolia Autonomous Region, between the new Balhu Right Banner, the new Balhu Left Banner and the Zhalai Nuoer District, it is an irregular oblique rectangle, the long axis is the southwest to the northeast direction of the vertebral rock, the lake is 93 kilometers long, the maximum width is 41 kilometers, the average width is 32 kilometers, the circumference of the lake is 447 kilometers, and the water storage capacity is 100 million cubic meters.

It is the largest lake in Inner Mongolia, the fifth largest lake in China, and the largest freshwater lake in the arid region of central Asia. <
