Poyang lake location
Poyang Lake is located in the north of Jiangxi Province, on the south bank of the Yangtze River. It is the largest freshwater lake in China. The flood level is 21.69m, the lake length is170.0km, the average width is17.3km, the area is 3,960m2, the maximum water depth is 29.19m, the average water depth is 5. 1 m, and the water storage capacity is 276. Poyang Lake is mainly replenished by surface runoff and precipitation. The main rivers entering the lake are Ganjiang River, Fuhe River, Xinjiang River, Raohe River and Xiushui River. Northwest of the lake is Lushan Mountain, a summer resort.
Poyang Lake is173km long from north to south, 74km wide from east to west, with an average width of16.9km, a coastline length of1200km, and a water level of 2 1.7 1 m at the mouth of the lake, with an area of 3,283km2 and an average water depth of 8.4m..
Poyang Lake is a huff-and-puff lake with huge seasonal changes, and the area and water storage capacity are quite different between high water season and low water season. During the year, the variation range of water level was 9.79-15.36m, and the variation range of absolute water level was16.69m.. At the turn of spring and summer every year, the lake rises sharply, the water surface expands rapidly, and the smoke waves are vast; But in winter, the lake drops sharply, and the beach is exposed, leaving only a few winding waterways on the lake. Form a landscape of "one flood and one drought".
Annual average water level12.86m; The highest water level of 22.59 meters appears at (65438+1July 3, 19981), with an area of 4,070 square kilometers and a storage capacity of 30 billion cubic meters. The lowest water level of 5.90 meters appeared on (1963 February 6), with an area of only 146 square kilometers and a storage capacity of 450 million cubic meters.
2. Dongting Lake
Dongting Lake, located in the north of Hunan Province and south of the middle reaches of the Yangtze River, is the second largest freshwater lake in China. Its area is about 3 100 square kilometers in dry season, more than 3900 square kilometers in flood season, and the total area of the lake area is 18000 square kilometers. Volume120 billion cubic meters. The main rivers entering the lake are Xiangjiang, Zishui, Shui Yuan and Lishui, and Yueyang Tower overlooks Dongting Lake.
It consists of four great lakes, Dongting Lake and Datong Lake in the east, west and south. In the south of Hubei Province, the north of Hunan Province and the south bank of the Yangtze River. In the north, there are four ports, Songzi, Taiping, Ouchi and Tiao County (1958 Jietiao County), which draw river water for collection, and in the south and west, there are Xiangjiang River, Zishui River, Yuanjiang River and Lishui River for injection. The lake drains into the Yangtze River through Chenglingji. Usually, the flood peaks of four rivers entering the lake in a year are staggered. Therefore, it has the regulation function of "accommodating four waters" and "swallowing the Yangtze River", which reduces the flood pressure in the middle reaches of the Yangtze River. If "rivers and lakes rise together", it will be easy to flood.
Because four rivers and four mouths carry a lot of sediment, about 1.28 billion tons of sediment are deposited at the bottom of the lake every year. The lake area 1825 was about 6,000 square kilometers, 1890 was 5,400 square kilometers, 1932 was 4,700 square kilometers, and 14 1962 was reduced to 314. At present, the lake area is 2820 square kilometers based on the elevation of 34.5 meters. Formerly known as "Eight Hundred Li Dongting", it was divided into many lakes, large and small.
The water level changes 13.6 meters, which is known as "the frost falls into the hole and the court dries up". 1952 Jingjiang flood diversion project and flood storage and detention area were built, so that part of the flood was discharged into the flood diversion area, and the dike waterway in the lake area was renovated, reducing the threat of flood to Dongting Lake area. The lakeside plain of Dongting Lake has flat terrain, fertile land, mild climate and abundant rainfall, and is rich in rice and cotton. The lake is rich in aquatic products and convenient for shipping.
Dongting Lake is now the most important catchment and flood storage area in the Yangtze River basin. Due to serious sediment deposition, Dongting Lake has been divided into three parts: East Dongting Lake, South Dongting Lake and West Dongting Lake.
Dongting Lake is a typical water-storage lake, which has many functions, such as irrigation, shipping, fishery production, water supply, water intake, climate regulation and environment beautification. With fertile soil, mild climate, abundant rainfall and abundant natural resources, Lake District is an important production base of commodity grain, freshwater fish, cotton and linen in China.
3. Taihu Lake
Taihu Lake is located at the junction of Jiangsu and Zhejiang provinces, in the south of the Yangtze River Delta, and the lake area belongs to Jiangsu Province. It is the largest lake in the eastern coastal area of China and the third largest freshwater lake in China. The total area of the lake area is about 3 100 square kilometers, and the water area is about 2420 square kilometers.
The third largest freshwater lake in China is in the south of Jiangsu Province and the north of Zhejiang Province. The Lake District belongs to Jiangsu Province. In ancient times, it was called Zhenze, Juqu, Lize and Five Lakes. It used to be thought that it was formed by sedimentation in the lower reaches of the Yangtze River and the ancient bays of Qiantang River. There is a saying that the lake swing area formed by meteorite impact nearly ten thousand years ago has produced many lakes, such as Taihu Lake, Yangcheng Lake, Dianshan Lake, Jinji Lake, Dushu Lake and Fen Lake. The violent impact of celestial bodies caused strong earthquakes and other damages, so the ancients called Taihu Lake a shock. When the normal water level is 3 meters, the lake area is 2250 square kilometers, the average water depth is 1.94 meters and the storage capacity is 2.72 billion cubic meters.
There are two main sources of water: one is Tiaoxi from Tianmu Mountain, Zhejiang Province, which is divided into more than 70 ports below Huzhou City; The other is Jingxi from the northern foot of Yili Mountain in Jiangsu Province, which is divided into more than 60 ports such as Taipu and Baidu. Taihu Lake system flows into the Yangtze River from more than 70 river ports on both sides of the northeast, with Loujiang River (downstream called Liuhe), Wusong River (downstream called Suzhou River) and Huangpu River as the main rivers ("Three Rivers"). Huangpu River is the largest waterway, accounting for about 80% of the total water output. Other rivers and ports have small flows, and every time they flow backwards because of high tide or rising river water.
There are more than 80 large and small lakes/kloc-0 in the whole Taihu Lake system, and the large and small rivers entering and leaving the lakes form a water system as dense as a spider web. It is very beneficial to shipping, irrigation and regulating the water level of rivers and lakes. Most of the old river networks in Taihu Plain are shallow, narrow and tortuous, and the irrigation and drainage system is disordered, so the flood disaster is still a potential threat. Unified planning is implemented, blind reclamation is prohibited, river courses are regulated, flood discharge capacity is increased, and irrigation and water diversion benefits are improved.
4. Hongze Lake
Hongze Lake is located on the alluvial plain in the middle reaches of Huaihe River in the west of Hongze County, Jiangsu Province, and is the fourth largest freshwater lake in China. Hongze Lake is a shallow lake with a water depth of less than 4 meters and a maximum water depth of 5.5 meters. The total area of the lake area is 2069 square kilometers. The source of lake water, besides atmospheric precipitation, mainly depends on river water. Rivers flowing into Hongze Lake include Huaihe River, He Sui River, Bianhe River and Anhe River.
Because Hongze Lake is developed in the depression of alluvial plain, the lake bottom is shallow and flat, and the bank slope is low and gentle. The bottom of the lake is 4-8 meters higher than the eastern part of the northern Jiangsu plain, which is a "suspended lake". Before harnessing the Huaihe River, Hongze Lake covered the Wang Yang, with neither a fixed shore nor a certain shape. With reference to harnessing the Huaihe River, Hongze Lake was also harnessed. At present, the east dike of the lake area is 50 meters wide and 67 kilometers long, almost all of which are composed of basalt strips. This long levee not only protects thousands of fertile fields and thousands of villages and towns in the downstream area, but also provides convenience for shipping, power generation and irrigation by retaining abundant water sources.
Hongze Lake is a shallow lake with a water depth of less than 4 meters and a maximum water depth of 5.5 meters. The source of lake water, besides atmospheric precipitation, mainly depends on river water. Rivers flowing into Hongze Lake are concentrated in the west of the lake, including Huaihe River, He Sui River, Bianhe River and Anhe River. Sanhe and Subei irrigation canals are the main rivers that Hongze Lake discharges into the Yangtze River and enters the sea.
Hongze Lake is rich in aquatic resources, and there are nearly 100 kinds of fish in the lake, mainly carp, crucian carp, bighead carp, green grass, silver carp and so on. The crabs in Hongze Lake are also famous. In addition, the aquatic plants in Hongze Lake are very famous. Reed is almost all over the lake, and it is difficult for even ships to sail in lush places. Lotus root, Euryale ferox and water chestnut are very famous in history, and there was a saying that "water chestnut with the head of a chicken is half a year's grain".
5.Weishan Lake
Weishan Lake is located in Weishan Lake, Shandong Province, also known as Nansi Lake. It is located in Weishan County at the junction of Shandong and Jiangsu in China. It consists of four interconnected lakes, namely Weishan Lake, Zhaoyang Lake, Nanyang Lake and dushan lake. Weishan Lake has a total length of 230 kilometers from north to south, a width of 6.8 kilometers to 27.6 kilometers, a perimeter of 45 1 kilometer, a total area of 1.266 square kilometers, a controllable storage capacity of 1.73 billion cubic meters, and a maximum storage capacity of 473.65438 billion cubic meters.
Average water depth 1.7m, with the deepest depth of 3m in flood season. The drainage area is 3 1.700 square kilometers, and the Beijing-Hangzhou Grand Canal runs through the whole northern Hunan, which is the largest freshwater lake in northern China, Poyang Lake map! It is also the fifth largest freshwater lake in China. In a narrow sense, Weishan Lake refers to a lower-level lake with a dam at the waist of 1960 Weishan Lake, which forms a vast Weishan Lake with Zhaoyang Lake, dushan lake Lake and Nanyang Lake.
Extended data
Freshwater lake refers to the lake that accumulates on the surface in the form of fresh water, which can be divided into closed and open types: most closed freshwater lakes are located in high mountains or inland areas, and there are no obvious rivers flowing in and out; An open freshwater lake may be quite large, with islands and many rivers flowing in and out. Freshwater lakes are generally outflow lakes; Because the water source can be renewed and replenished, the salt content of freshwater lake is very low.

Is it really just a coincidence that the four freshwater lakes on the map are very similar in shape to the four great beasts? Although the shapes of the four freshwater lakes are similar to those of the four beasts, the four beasts are the products of fairy tales after all. If the novel says that the four lakes are the embodiment of four beasts, some people will believe it. In real life, this may really be just a coincidence, which happened to be discovered by a willing heart.
In fact, the geography and culture of our country are amazing. The whole map of our country is like a chicken standing on the earth, and the geographical environment in many parts of our country is also wonderful.

Poyang Lake plays a great role in regulating the water level of the Yangtze River, conserving water resources, improving the local climate and maintaining the ecological balance in the surrounding areas.
From the map, the shape of the whole Poyang Lake resembles the white tiger among the four great beasts in ancient China, and the white tiger is the god of the west, the god of war and cutting, and has always been loved by military strategists. So many things of military strategists are related to it, such as the white tiger statue on the military symbol and the white tiger statue on the military flag. Even "White Tiger Star Descending from Earth" is often used to describe such a brave general.
Hongze Lake is located in the west of Jiangsu Province, which was named only in the Tang Dynasty. Much like a phoenix spreading its wings and flying, just like Suzaku among the four ancient beasts.
The overall shape of Taihu Lake on the map is like Xuanwu among the four great beasts in ancient China. Taihu Lake can be said to be located in a relatively warm climate, with astronomical rain in summer and cold and dry in winter. As for its formation process, it is said that it is a pit formed on the ground after the meteorite fell.
