What is China s largest freshwater lake and where is it?

The largest freshwater lake in China is Poyang Lake, located in the northern part of Jiangxi, with a total area of 3,283 square kilometers.

Attached: Introduction to Poyang Lake.

Poyang Lake is an ancient faulted lake basin, which sank into a huge basin about 100 million years ago, and became a lake with water six or seven thousand years ago. Due to the diversion of the Yangtze River and human activities in history, a large amount of sediment was deposited in the lake, resulting in the continuous shrinkage of the lake. Poyang Lake brings together the water of the five rivers of Jiangxi, Fu, cymbal, Xin and Xiu, and then leaks into the main stream of the Yangtze River.

With the change of water volume, Poyang Lake has a large rise and fall range, which has the function of natural water regulation and flood storage.

Poyang Lake is 173 kilometers long from north to south, 74 kilometers wide from east to west, the average width is 1200 kilometers, the lake area is 3283 square kilometers (the water level of the lake mouth is meters), the average water depth is meters, the deepest meters are about 27.6 billion cubic meters, it is the largest freshwater lake in China. It accommodates the five major rivers of Ganjiang, Fuhe, Xinjiang, Rao and Xiuhe. After the storage and storage, it flows into the Yangtze River, the largest river in China, from the mouth of the lake, and the amount of water flowing into the Yangtze River every year exceeds the total water volume of the three rivers of the Huang, Huai and Hai rivers, and it is a seasonal, throughput lake.

The basin of Poyang Lake covers an area of 10,000 km2, accounting for about 97% of the basin area of Jiangxi Province and 9% of the area of the Yangtze River basin: the average annual runoff of the water system is 152.5 billion cubic meters, accounting for about the average annual runoff of the Yangtze River basin.

1637 meters, the water storage accounts for 1 5 of the world's total freshwater reserves. Lake Superior, the northwestern part of the Great Lakes of North America around Lake Baikal, has a total of 336 rivers of all sizes that flow into the lake, the largest being the Selenga River, and from the lake.

The largest freshwater lake in China is Poyang Lake.

The lakes in the eastern plains of China are dominated by freshwater lakes, among which the lakes in the middle and lower reaches of the Yangtze River are the most numerous lakes in the region. There are many rivers and lakes in the middle and lower reaches of the Yangtze River, known as the "water town in the south of the Yangtze River".

In the middle and lower reaches of the Yangtze River, there are three major freshwater lakes in China, namely Dongting Lake, Poyang Lake and Taihu Lake. These three lakes are like three pearls strung on the main stream of the Yangtze River, which respectively nourish the people living in the surrounding Dongting Lake Plain, Poyang Lake Plain and Taihu Lake Plain. These three lakes are also the three largest freshwater lakes in China, and Poyang Lake in Jiangxi Province is the largest freshwater lake in China, covering an area of about 3,150 square kilometers.

Poyang Lake is vast, and its lake surface is very flexible due to seasonal changes, and it has always been said that "a flood is a sign and a dry water line". During the dry season, the lake covers an area of 500 square kilometers and during the flood season it can reach 3,960 square kilometers.

Although it is located in the desert area of the earth, it is blessed with an average annual precipitation of more than 1,000 mm due to the influence of the southeast monsoon with a large amount of water vapor, thus forming a humid monsoon climate of "Zeguo Fangcao is green, plum yellow smoke and rain, maple red sends summer return, and green bamboo welcomes snow", becoming a famous land of fish and rice. It is also a unique large lake in the ecological environment of the global return to the desert belt, and is also known as the "pearl of the return desert belt".

The largest freshwater lake in China is Poyang Lake.

With a maximum area of 3,150 square kilometers, Poyang Lake ranks second among the largest lakes in China (the largest is Qinghai Lake, the largest saltwater lake, with a maximum area of about 4,543 square kilometers).

Poyang Lake, known as Peng Li, Peng Lize and Peng Ze in ancient times, is located in the north of Jiangxi Province, in Jiujiang, Nanchang and Shangrao cities. Poyang Lake is mainly fed by water sources such as the Gan River, Xiu River, Xinjiang River, Rao River and Fu River, and flows into the Yangtze River from south to north near Shizhong Mountain, Hukou County, Jiujiang City.

The lake body is usually bounded by Songmen Mountain between Duchang and Wucheng, and is divided into two lakes, north and south (or east and west). The northwest of Songmen Mountain is the North Lake, or the West Po Lake, the lake is narrow, it is actually a long and narrow road through the river and the port, it is 40 kilometers long, 3 5 kilometers wide, and the narrowest part is about one kilometer. The southeast of Songmen Mountain is the South Lake, or Dongpo Lake, the lake is vast, is the main body of the lake area, 133 kilometers long, the widest point is 74 kilometers.

The southern lake area is the main body of Poyang Lake, accounting for about four-fifths of the total area of the lake.

The natural environment of Poyang Lake:

The Poyang Lake area has abundant sunshine, abundant light energy resources and strong solar radiation. Cold in winter and hot in summer, 10 high accumulated temperature. There is relatively little precipitation and less surface runoff, but there is more river runoff and abundant water resources.

In autumn and winter, affected by the shortage of water sources such as the Xiuhe River and the Ganjiang River system, Poyang Lake enters the dry period from autumn and winter to mid-spring of the following year, forming a vast grassland with "blue fields and boundless clouds". The river beach is connected to 9 separate small lakes and is the best place for migratory birds to migrate and spend the winter. In 1992, Poyang Lake was included in the "List of Wetlands of World Importance", and the main objects of protection are rare migratory birds and wetland ecosystems.

It is Poyang Lake, Poyang Lake, formerly known as Peng Li, Peng Lize, Peng Ze, located in the north of Jiangxi Province, located in Jiujiang, Nanchang, Shangrao City, is the largest freshwater lake in China.

Poyang Lake is one of the main tributaries of the middle and lower reaches of the Yangtze River, and is also a water-flowing, through-flow and seasonally important lake in the Yangtze River Basin. The area of the lake is 3,150 square kilometers at a flat water level (14 m to 15 m) and more than 4,125 square kilometers at a high water level (20 m). But at low water (12 meters) it is only 500 square kilometers.

Poyang Lake inherits five rivers and connects to the Yangtze River, becoming the "catchment basin" of the province and the "transfer station" of the five rivers entering the river. The hydrological characteristics are that of a shallow lake of throughput and seasonality. The large variation of the seasonal and inter-annual differences in the water level difference between the year remains unchanged, and the intra-annual variation is the same, and the maximum inter-annual variation is reached.

For example, the water level of Xingzi during the flood in 1976 was 21 meters, and the lake area was about 3,841 square kilometers, with a volume of about 26 billion cubic meters; During the dry season, the water level of Xingzi is 16 meters, the lake covers an area of about 526 square kilometers, and the capacity is only about 900 million cubic meters. "The high water is a lake, and the low water is like a river", a flood is a flood, and a line of dry water is the natural geographical characteristics of Poyang Lake. Poyang Lake plays a huge role in regulating the water level of the Yangtze River, conserving water, improving the local climate and maintaining the ecological balance of the surrounding area.

Coastal peaks. Lushan, located in the south of Jiujiang City, Jiangxi Province, stands majestically on the shore of the Yangtze River, Poyang Lake, 7 kilometers away from the Pingfeng bayonet of Poyang Lake Changling in the east, is a metamorphic rock broken stone mountain, which rises from the ground, the elevation of the main peak Dahanyang Peak is 1474 meters. Famous for its majestic, strange, dangerous and beautiful, it is known as the reputation of "Kuanglu Qixiu is the best in the world", it is a world geopark and a national geopark of China, and it is also a famous summer resort, and it was once the "summer capital" of the Kuomintang. It is not only a famous scenic mountain at home and abroad, but also a famous Buddhist mountain, the birthplace of the Pure Land sect of Chinese Buddhism, and the famous temples include Donglin Temple, Wanshan Temple, Haihui Temple, Guizong Temple, Qixian Temple, etc.

Nanshan, facing Duchang Town across the East Lake from Duchang Town, Song Dynasty famous writers Su Dongpo, Su Zhe and Huang Tingjian have visited here. There are also seven unique "over Duchang" stone inscription tablet of Su Dongpo on the mountain, and there are places of interest and historic sites such as Nanshan Temple, Yelao Spring, Sutra Turning Platform, Eight Immortal Stones, etc.

Shizhong MountainShizhong Mountain is located at the north and south ends of Hukou County, south of Shangshizhong Mountain, close to Poyang Lake; Xiashi Zhongshan is located in the north, standing at the intersection of Poyang Lake and the Yangtze River, choking the river and controlling the lake, it is known as the "key to the rivers and lakes", and has always been a place for soldiers to fight. Zhou Yu, Zhu Yuanzhang, the Taiping Army and even Li Liejun in modern times have all fought here; During the Liberation War, Shizhong Mountain was the starting point of the Western Front of the River Crossing Campaign. The Song Dynasty poet Su Dongpo wrote "The Story of Shizhong Mountain" after a field trip, which made Shizhong Mountain famous all over the world.

Poyang Lake is the largest freshwater lake in China, located in the north of Jiangxi Province, with an area of 4,125 square kilometers and a national AAAA tourist attraction. To the northwest of the lake is the summer resort of Lushan.

It used to be Dongting Lake in Hunan, but after it was reduced by two-thirds of its area by enclosing the lake, Poyang Lake in Jiangxi Province rose from second to first. The largest saltwater lake in China is Qinghai Lake.

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 district has 41 islands and seven 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 spend the winter in Poyang Lake. Poyang Lake is the world of white cranes and a paradise for waterbirds. Poyang Lake is an important habitat and germplasm resource bank of the Yangtze finless porpoise, which has a stable number and reasonable population structure, and belongs to the high-quality population of the Yangtze finless porpoise.

As of 2016, there were about 450 finless porpoises in Poyang Lake, five times the number of finless porpoises in Dongting Lake and half of all of China.

Poyang Lake is located in the middle and lower reaches of the Yangtze River.

Poyang Lake is the largest freshwater lake in China, located at the junction of Tawau Lake from Jiujiang River to the mouth of the lake, and is connected to the water of the five rivers of Jiangxi, Fu, Xin, Rao and Xiu, and the Yangtze River, the largest river in Wuguo. Under normal water conditions, Poyang Lake covers an area of 3,914 square kilometers and has a volume of 30 billion cubic meters, and its annual flow into the Yangtze River exceeds the total water volume of the three rivers of the Yellow River, Huai River and Haihai, and is the regulator of the Yangtze River's water volume.

The largest saltwater lake in Tongzheng in China is Qinghai Lake (about 4,256 square kilometers).

The largest freshwater lake in China is Poyang Lake (about 2,567 square kilometers).Qinghai Lake, also known as Cuowenbu, which means blue sea in Tibetan, is located in the Qinghai Lake Basin in the northwest of Lianglunna, Qinghai Province, and is not only the largest inland lake in China, but also the largest saltwater lake in China. It is formed by the fault collapse between Datong Mountain, Riyue Mountain and Nanshan Mountain in Qilian Mountain.

Poyang Lake, known as Peng Li, Peng Lize and Peng Ze in ancient times, is the largest freshwater lake in China and the second largest lake in China, located in the north of Jiangxi Province, on the south bank of the middle and lower reaches of the Yangtze River, and is the second largest lake in China after Qinghai Lake.

Poyang lake. Poyang Lake is located at the junction of rivers and lakes from Jiujiang to Hukou, and is connected to the water of the five rivers of Jiangxi, Fu, Xin, Rao and Xiu, and the Yangtze River, the largest river in China. Under normal water level, Poyang Lake covers an area of 3,914 square kilometers and has a volume of 30 billion cubic meters, and its annual flow into the Yangtze River exceeds the total water volume of the Huang, Huai and Hai rivers, and is the regulator of the Yangtze River's water volume.

Poyang Lake is the largest freshwater lake in China.

Under normal water levels, Poyang Lake covers an area of 3,914 square kilometers and has a volume of 30 billion cubic meters. The shape of Poyang Lake is wide in the south and narrow in the north, resembling a gourd. From south to north, there is a slender narrow channel that communicates with the Yangtze River.

Poyang Lake, which is connected to the water of the five rivers and the Yangtze River, is a tributary of the Yangtze River and plays a role in regulating and storing water for the Yangtze River.

Especially in the flood season, the role of Poyang Lake in regulating and storing cannot be underestimated. Because there are too few tributaries in the lower reaches of the Yangtze River, Poyang Lake is the last reservoir before the Yangtze River enters the lower reaches of the Yangtze River, which has a great impact on the lower reaches of the Yangtze River, the Jianghuai River and the Taihu Lake basin. Guarding Poyang Lake ensured the safety of the middle and lower reaches of the Yangtze River.

Scenic features

Poyang Lake is the largest freshwater lake in China, with a length of about 170 kilometers and a width of 74 kilometers at its widest point. Shaped like a large gourd, it hangs upside down on the south bank of the Yangtze River. The five main rivers of Ganjiang, Fuhe, Rao, Xinjiang and Xiuhe supply water from the west, south and southeast respectively, and then flow into the Yangtze River.

In the dry season, the water falls and the beaches are dotted, and the meadows and wetlands are green. In 1980, the Poyang Lake Nature Reserve was established with an area of 35,000 hectares, and in 1988, the Poyang Lake Migratory Bird National Nature Reserve was established with an area of 22,400 hectares.

The water level of Poyang Lake varies greatly during the flood period and dry season every year, and in October and March of the following year, the water falls out of the beach, and the fish, shrimp, snails, mussels and various aquatic plants are abundant, which is a paradise for migratory birds to winter and inhabit.
