What is the largest dammed lake in our country?

The largest dammed lake in China is Jingpo Lake, which is also the second largest alpine dammed lake in the world.

Jingzhi Lake is located in the south of Mudanjiang City, Heilongjiang Province, with an area of 95 square kilometers. After five volcanic eruptions, Jingpo Lake is a rare alpine lake in the world, a famous scenic spot and a summer resort.

The largest dammed lake in China is Jingpo Lake in Heilongjiang Province.

A dammed lake is a lake formed by a landslide that blocks a valley, a river valley or a riverbed due to volcanic lava flows, moraines or the collapse of mountain rocks caused by ** activities.

Jingpo Lake in Heilongjiang Province is the largest volcanic dammed lake in China. It is a typical lava dam lake formed by a volcanic eruption about 10,000 years ago, about the middle and late Quaternary period, and the basalt flow formed a natural dammed embankment with a width of 40m and a height of 12m near the Hanging Water Tower, which intercepted the outlet of the Mudanjiang River and raised the water level. The average depth of the lake is 40 meters, gradually deepening from south to north, the deepest depth reaches 62 meters, the length of the lake body is 50 kilometers, the widest point is 9 kilometers, the narrowest place is also 300 meters in the dry period, the whole lake is divided into four lake areas: North Lake, Middle Lake, South Lake, and Upper Lake, with a total area of square kilometers.

Jingpo Lake in Heilongjiang Province is the largest dammed lake in China, formed by basalt overflow dams in the upper reaches of the Mudanjiang River, 50 kilometers southwest of Ning'an, Heilongjiang Province.

Jingpo Lake, the largest alpine dammed lake in China and the second largest in the world, is located on the main stream of the Mudanjiang River, a tributary of the Songhua River, in the southwest of Ning'an County, Heilongjiang Province, China, 50 kilometers away from Ning'an City, with an altitude of 351 meters. The average depth of the lake is 40 meters.

Wudalianchi, located in the west of Wudalianchi City, Heihe City, Heilongjiang Province, belongs to the dammed lakes on the Bai River, a tributary of the Songhua River, a tributary of the Nenjiang River, a tributary of the Nemur River. Wudalianchi is a volcanic dam lake formed by the lava magma emitted by the volcano that blocked the old channel of the Baihe River (Shilong River), forming five bead-shaped volcanic dammed lakes.

A dammed lake is a lake formed by blocking a river valley or riverbed after a landslide caused by a volcanic lava flow or a landslide caused by ** activity. Lakes formed by the interception of volcanic lava flows are also known as lava dam lakes.

There are four processes in the formation of a dammed lake: first, the original water system; Second, the original water system is blocked by blockages. Third, after the river valley and riverbed are blocked, the flowing water gathers and overflows in all directions. Fourth, when the water is stored to a certain extent, a dammed lake is formed.

Once the dammed lake bursts, it will form a flood peak downstream, and if it is not properly disposed of, it will cause major disasters.

A dammed lake is a lake formed when a river is blocked by foreign material. It is often caused by landslides, landslides, mudslides, moraines, lava flows from volcanic eruptions, and flowing sand dunes. However, the blockages of dammed lakes are not fixed and unchanging, they can also be scoured, eroded, dissolved, collapsed, and so on.

Once the blockage is broken, the lake overflows and pours down, creating a dangerous flood.

China is a country with very abundant water resources, but due to the complex shape of the ground and the changeable climate, dammed lakes often occur. At present, the five major existing dammed lakes in China are Bayankala, Juyanhai, Altun Mountain, Keketuohai and Dianchi Lake in Xinjiang. The formation of these lakes is closely related to factors such as crustal movement and river flow.

Bayankala is a dammed lake located in Aheqi County, Kizilsu Kirgiz Autonomous Prefecture, Xinjiang. The formation of this lake is related to the occurrence of the magnitude ** in Xinjiang and Tajikistan in 1997. ** triggered the collapse of the Bayanka Lead Hula Mountain, forming something like a "plug", which prevented the river from flowing out normally, thus forming the lake.

Juyanhai is the largest inland lake in China, located at the junction of Gansu and Ningxia. There are two main reasons for its formation: first, the general decline of terrain in North China, resulting in the inability of the rivers that originally flowed to the Yellow Sea to discharge normally; Second, the siltation of the Yellow River's vast amount of sediment has gradually turned an empty area into a lake.

Altun Mountain Dam Lake is located in Yiwu County, Hami Prefecture, Xinjiang Uygur Autonomous Region, western China. It was formed as a result of a landslide that formed a dammed dam in the upper reaches of the river, which eventually formed the Altun Mountain Dam Lake. At present, the lake has become a tourist attraction in Xinjiang.

Xinjiang Keketuohai Dam Lake is an ancient lake, located in the center of the Tarim Basin, due to the late crustal movement in North China in ancient times, the terrain declined, and the sea surface formed by the precipitation of the outflow river and the recharge of groundwater. Keketuohai was originally an endorheic lake, but later became a dammed lake due to the decline of the terrain.

Dianchi Lake is a lake in Yunnan Province in southern China and the largest freshwater lake in southern China. There are many reasons for the formation of Dianchi Lake, including topographic changes brought about by crustal movements, as well as karstification. The reason why Dianchi Lake has become a dammed lake is more due to the lack of human development activities and changes in the hydrological environment.

In general, although the five major dammed lakes in China are formed due to various reasons, they all have their own unique geographical, climatic and human factors. In dealing with the problems of these dammed lakes, multi-faceted coordination and countermeasures are needed to achieve an effective solution and ensure the safety of people's lives and property. <>

1.One is the original water system;

2.Second, the original water system is blocked by blockages.

3.After the valley and riverbed are blocked, the flowing water gathers and overflows in all directions.

4.Fourth, when the water is stored to a certain level of silver ridge, a dammed lake is formed.

The dammed lake is a lake formed by the landslide and landslide body caused by the collapse of the mountain oak and wide rocks caused by volcanic lava flows, moraines or beams caused by the activity of the mountain, and landslides and other reasons to block the valley, river valley or riverbed. The lake formed by the lava flow of Huomu Orange Mountain is also called the lava dam lake.
