China is a vast area, as one of China s four major freshwater lakes?

They are Poyang Lake, Taihu Lake, Dongting Lake, and Hongze Lake, which are introduced as follows:

1. Poyang Lake

Poyang Lake is located in the world's largest freshwater lake in Jiangxi Province, the shape of this lake on the map resembles a white tiger, which is shocking, not only is the landscape around Poyang Lake is also very beautiful, and birds stop at Poyang Lake every year, and there are many famous landscapes nearby. As the largest freshwater lake, Poyang Lake is also worthy of its name, and in the Tang Dynasty, this lake was already 6,000 square kilometers, but later with natural changes, Poyang Lake has changed and is divided into two parts.

2. Taihu Lake

As a famous freshwater lake, Taihu Lake is characterized by its beauty, and it is famous for its beauty, but there are many legends about this lake, and I think the most interesting legend is the storm legend, which is said to be because of the arrival of the big storm, which caused the water to increase continuously, thus forming Taihu Lake, although this statement is also possible, but I think it is not very likely to be realized. The shape of this lake on the map resembles a basalt, and its specialties are pearls, Taihu Lake white fish and other aquatic products.

3. Dongting Lake

Dongting Lake is located in Hunan Province, is the most popular lake for tourists, many people want to see the legendary Dongting Lake, which all originated from an ancient poem we learned when we were children, in which the poem about Dongting Lake is "looking at the Dongting Mountains and Rivers, ** a green snail in the plate", this poem deeply aroused our curiosity about Dongting Lake, not only these two verses describing the beauty of Dongting Lake, there are many poets in history who are amazed by the beauty of Dongting Lake, the shape of this lake on the map resembles a green dragon.

4. Hongze Lake

The shape on the map of Hongze Lake resembles a red bird, this lake is not well known to the public, but it is not to be underestimated, it covers an area of more square kilometers, and there are many legends about this lake, it can be seen that in the process of historical migration, the mystery of this lake is still very high.

Although these freshwater lakes seem to have little in common, they are actually located in the Yangtze River Delta, and the shape on the map is the legendary four sacred beasts, which makes people curious that the existence of the four freshwater lakes means the existence of mysterious legends, and I hope that the future can be further studied.

The smallest is Hongze Lake located in the western plain of Hongze District, Jiangsu, the third largest freshwater lake is Taihu Lake, located at the junction of Jiangsu and Zhejiang provinces, the second largest freshwater lake, Dongting Lake, located in the north of Hunan Province, the first largest freshwater lake is Poyang Lake, located in the north of Jiangxi Province, on the south bank of the Yangtze River.

The four major freshwater lakes in China are: Poyang Lake, Dongting Lake, Taihu Lake, and Hongze Lake. In fact, there is also a Chaohu Lake, which is also a freshwater lake in China.

Poyang Lake, Dongting Lake, Taihu Lake, Hongze Lake, China's freshwater lakes are mainly distributed in the middle and lower reaches of the Yangtze River plain, the lower reaches of the Huai River and the southern part of Shandong, and the lake area in this area accounts for about one-third of the total lake area in China.

They are Poyang Lake, Dongting Lake, Taihu Lake and Hongze Lake, all of which are lakes with low salt content, mainly distributed in the middle and lower reaches of the Yangtze River Plain, the lower reaches of the Huai River and the southern part of Shandong.

The largest freshwater lake in China is located in Jiangxi Province.

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. It is one of the main tributaries of the middle and lower reaches of the Yangtze River, and is also a water-flowing, throughput-type and seasonally important lake in the Yangtze River basin, with a water area of 3,150 square kilometers at a flat water level (14 to 15 meters), more than 4,125 square kilometers at high water level (20 meters), and 500 square kilometers at low water level (12 meters).

It is mainly supplied by the water sources of 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, which plays a huge role in regulating the water level of the Yangtze River, conserving water sources, improving the local climate and maintaining the ecological balance of the surrounding areas. At 6 o'clock on September 23, 2022, the water level of Poyang Lake refreshed the lowest level in history, and Jiangxi issued a red warning for dry water for the first time.

Location Realm:

Poyang Lake is the largest freshwater lake in China and is located in the northern part of Jiangxi Province. 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.

The lake body is 173 kilometers long from north to south, the average width from east to west is 74 kilometers, the narrowest is 3 kilometers, the lake basin is inclined from southeast to northwest, the ratio is 12 to 1 meter, the shoreline is about 1200 kilometers long, the lake morphological coefficient is 109, and the development coefficient (bending coefficient) is 6. There are 41 islands in the lake with an area of 103 square kilometers. 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 largest freshwater lake in China is Panyang Lake.

Po (pó) Yang Lake, formerly known as Peng Lize, Peng Ze, Guanting Lake, Yanglan and Danshi Lake, is located in the northern part of Jiangxi Province, located in the three cities of Jiujiang, Nanchang and Shangrao, and is the largest freshwater lake in China and the second largest lake in China, second only to Qinghai Lake.

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 flat water level (14 m to 15 m) and more than 4,125 square kilometers at high water level (20 m). However, at low water level (12 meters) it is only 500 square kilometers, and according to 2008 hydrological data, when the lake is meters, the lake area is 4,070 square kilometers.

Poyang Lake receives water from the five major rivers of Ganjiang, Fuhe, Xinjiang, Raohe and Xiuhe, as well as Boyang River, Zhangtian River and Tongjin River, and flows into the Yangtze River at the mouth of the lake after storage and storage.

Hydrological characteristics of Poyang Lake:

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.

The water level and the area of the lake vary greatly in a year, such as the water level of Xingzi during the flood in 1976 was 21 meters, the lake area is about 3,841 square kilometers, and the volume is about 26 billion cubic metersDuring 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, and a line of dry water" is the natural geographical feature of Poyang Lake. Poyang Lake plays a huge role in regulating the water level of the Yangtze River, conserving water sources, improving the local climate and maintaining the ecological balance of the surrounding area.

The largest freshwater lake in China is Poyang Lake.

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. Poyang Lake, formerly known as Pengze, is located in the north of Jiangxi Province and on the south bank of the middle and lower reaches of the Yangtze River.

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.

The role of Poyang Lake

1. Regulating and storing water: 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 in the Yangtze River. Especially in the flood season, the role of Poyang Lake in regulating and storing cannot be underestimated.

Due to the small number of 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.

2. Natural geographical conditions and seasonal characteristics: Poyang Lake has superior geographical location and natural conditions, and is a large reservoir with multiple functions. Poyang Lake has a prominent position in the middle and lower reaches of the Yangtze River, especially in Jiangxi Province, and has made great contributions to the economic development here.

The seasonal characteristics of Poyang Lake are distinctive. The difference between high and low water levels can reach as much as 10 meters. Due to seasonal changes, the lake expands and contracts relatively largely, and there has always been a saying that "one flood is a line, and one line of dry water".

Therefore, the vast smoke waves when the water is abundant and the cultural relics and monuments when the water is dry are revealed, which become the greatest added value brought by the seasonal characteristics of the lake.

The four major freshwater lakes in China refer to Poyang Lake, Dongting Lake, Taihu Lake, and Hongze Lake. Poyang Lake is the largest freshwater lake in China, with a vast area and good ecological environment, Dongting Lake was called Yunmeng in ancient times, with a long history, many natural landscapes and cultural landscapes, Taihu Lake is famous for its specialties throughout the country, and Hongze Lake is an important fishery and specialty production base in China.

The four major freshwater lakes in China are: Poyang Lake, Dongting Lake, Taihu Lake, and Hongze Lake.

The largest freshwater lake in China is Poyang Lake.

Poyang Lake is the largest freshwater lake in China, located in the northern part of Jiangxi Province, with an area of 3,960 square kilometers and 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 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.

Freshwater lakes

A freshwater lake is a lake that accumulates on the surface of the earth in the form of fresh water. Freshwater lakes are divided into two types: closed and open: closed freshwater lakes are mostly located in high mountains or inland areas, with no obvious river inflow and outflow; Open freshwater lakes can be quite large, with islands and multiple rivers flowing into and out.

Freshwater lakes are generally outflow lakes; Because the water source can be renewed, the water in freshwater lakes has a low salinity. The largest man-made freshwater lake in Asia is the Danjiangkou Reservoir and the source of water for the middle route of China's South-to-North Water Diversion Project.
