What type of lake does Poyang Lake belong to?

Poyang Lake should be a tectonic lake, because the Lushan Mountain on the west side of Poyang Lake is raised by crustal movement, and the east side becomes a graben, that is, Poyang Lake.

5 River Trail Lake. As we all know, in the flat plain area of the middle and lower reaches of the Yangtze River, there are no traces and conditions for the formation of rivers due to glacier movement in the prehistoric glacial season, so it cannot be a glacial lake; It can't be a dammed lake, Wenchuan ** clearly tells us the formation of a dammed lake, the dammed lake is due to the truncation of the mountain on the river caused by ** or landslides, resulting in the river can form a lake within a certain range, and at the same time has extreme instability, imagine that Poyang Lake is so worrying?; If you want a volcanic lake, you have to look at Changbai Mountain Tianchi and Tianshan Tianchi, which are lakes formed in extinct volcanic craters, and there are no extinct volcanoes in the plain area, let alone craters, so they will not be volcanic lakes; Looking at the tectonic lake, this kind of lake is due to the action of crustal movement, the two plates form a fault zone somewhere due to the growth (that is, the distance between the two plates from each other), and the rivers gather more and more here, and the simultaneous action of the two creates a tectonic lake, and our Poyang Lake does not exist in the gap between any large plates or small plates, so the possibility of a tectonic lake is ruled out; At the same time, our middle and lower reaches of the Yangtze River Plain are flat and the water flow is gentle, so it is more likely to be a river trace lake.

Poyang Lake is not the largest lake in China.

Poyang Lake, known as Peng Li, Peng Lize and Peng Ze in ancient times, is located in the north of Jiangxi Province, located in Jiujiang, Nanchang and Shangrao cities, and is the largest freshwater lake in China and the second largest lake in China. The lake basin is formed by the collapse and siltation of the earth's crust. In the Mesozoic Era, under the influence of the Yanshan movement, it subsided and became a basin, which covered a wide range of areas in the northern part of present-day Jiangxi, the Huangmei area of Hubei Province and the Susong and Wangjiang areas of Anhui Province.

Poyang Lake is the largest freshwater lake in China. The lake is divided into Lushan District, Hukou County, Xingzi County, Gongqing City, Duchang County, Yongxiu County, Xinjian District of Nanchang City, Poyang County, Yugan County, Nanchang County, Jinxian County and other areas of Jiangxi Province. When the water level of the lake is meters, the lake area is 4070 square kilometers.

Poyun Senyang Lake is connected to the Yangtze River by five rivers, becoming the "catchment basin" of the whole province, and its hydrological characteristics are a shallow lake of throughput type and seasonality.

The largest lake in our country:

Qinghai Lake, known in Tibetan as "Tsowenbu", meaning "blue sea", is located in the northeast of the Qinghai-Tibet Plateau in Qinghai Province, China, and is the largest lake in China, as well as the largest saltwater lake and endorheic lake in China, with a total area of square kilometers. Qinghai Lake is formed by the collapse of a fault between Datong Mountain, Riyue Mountain and Nanshan Mountain in Qinghai in the Qilian Mountains. The water of Qinghai Lake** mainly depends on surface runoff and lake surface precipitation.

Qinghai Lake is a tectonic fault lake, and the edge of the lake basin is mostly connected with the surrounding mountains by faults. In the early days of the lake 202 million years ago, it was originally a large freshwater lake that was well connected with the Yellow River water system, when the climate was mild and rainy, and the lake water was discharged into the Yellow River through the inverted river in the southeast, which was an outflow lake. By 130,000 years ago, due to neotectonic movements, the surrounding mountains were strongly uplifted, and from the end of the Pliocene, the Riyue Mountain and Yeniu Mountain in the eastern part of the lake rose rapidly, blocking the inverted river that originally flowed into the Yellow River.

Poyang Lake is the largest freshwater lake in China.

Poyang Lake is the largest freshwater lake in China, located in the northern part of Jiangxi Province, with an area of 4,125 square kilometers, and is a national AAAAA-level tourist attraction. To the northwest of the lake is the summer resort of Lushan. Poyang Lake Tourist Attraction mainly refers to the scenic spots and nature reserves in the lake area as a whole.

The lake area has 41 islands and 7 nature reserves.

There are more than 300 species of migratory birds in Poyang Lake, nearly one million, including more than 50 rare birds, and it is the largest bird sanctuary in the world. There are more than 4,000 Siberian cranes in the world. 90 of them wintered in Poyang Lake.

Poyang Lake is the world of white cranes and a paradise for waterbirds.

Which round waterway is the fairway:

Poyang Lake was the only waterway that entered Jiangxi from the north in ancient times. The mouth of the lake is the main gateway connecting the Poyang Lake waterway to the Yangtze River waterway. It is the waterway of Poyang Lake into the Yangtze River, 65 kilometers long, 3 14 kilometers wide, in the lake area, the east and west two major waterways are the main arteries of Poyang Lake water transport, Wucheng to the mouth of the lake is a waterway, and 1000 tons of ships can be navigated all year round.

To the north of Nanshan, there is a kilometer port road leading to Duchang Town Wharf.

After the confluence of the Ganjiang River and the Xiuhe River, the western waterway of Poyang Lake is formed, which leads to the mouth of the lake to the north and east. After the Xinjiang River enters the lake in Zhangjia, Ruihong Town, Yugan County, flows 9 kilometers northwest, passes through Niutou Mountain, the north of Beikou Bay to the mouth of the three rivers, and joins the water of the Fuhe River and the south branch of the Ganjiang River, so the mouth of the three rivers is named. In autumn and winter, the Sanjiangkou is revealed, which is the only way for Yugan County to navigate to Nanchang.

After the Rao River enters the lake in Yaoshan Mountain, Shuanggang Town, Poyang County, the main channel flows southwest along the west of Lianbei Wei to Longkou, and the right bank is a strip-shaped grassland with a width of kilometers. It flows 14 kilometers to the northwest of Longkou and flows 14 kilometers to the confluence of Huangshan and Kangshan River to form the east waterway of Poyang Lake, which is the main waterway of Poyang County into Poyang Lake and into the Yangtze River.

The Fuhe River in the northern lake area is artificially diverted from Chigang to the east, flows eastward through Qinglan Lake, and joins Jinxi Lake at Sanyang Street in Jinxian County, and the main channel flows eastward from south to north to Dahukou. In the territory of Yugan County in the southeast, the Kangshan River is the Li Helu River in Poyang Lake, the river is in the dry season, the average width is 400 meters, the general water depth is 5 meters, there are many lakes on both banks, mud and sand beaches, the whole process is navigable, and it is the main waterway of Yugan County into Poyang Lake and the Yangtze River.

The reason for the formation of the ridge in the shape of Poyang Lake is the wild turmoil.

a.The river was diverted.

b.The crater collapsed.

c.Glacial erosion.

d.Estuarine siltation + ground bending crust movement.

Correct answer: d

Poyang Lake is a typical wetland system. The wetland ecosystem of Poyang Lake refers to the water area of Poyang Lake that can remain still, flowing, freshwater, brackish, brackish, and the water depth does not exceed 6 m at low tide in natural, artificial, perennial, swampland, marshland, peatland or water area.

Poyang Lake, the largest freshwater lake in China and the second largest lake in China, is located in the northern part of Jiangxi Province, and is usually divided into two lakes, north and south, usually bounded by the Songmen Mountain between Duchang and Wucheng. The northwest of Songmen Mountain is the North Lake, or the West Po Lake, the lake surface is narrow, it is actually a long and narrow river port road, 40 kilometers long, 3 kilometers wide, 5 kilometers wide, and the narrowest part is about kilometers. The southeast of Songmen Mountain is the South Lake, or the East Po Lake, the lake is vast, it is the main body of the lake area, it is 133 kilometers long, and the widest point is 74 kilometers to Yantanchang.
