The lake body characteristics
173 kilometers north of Poyang Hunan, 74 kilometers west, an average width of 16.9 kilometers, a lake shoreline length of 1200 kilometers. A kilometer, the average water depth of 8.4 meters, the deepest part of about 25.1 meters, and about 27.6 billion cubic meters of water storage, which is the largest freshwater lake in China.

Panyang Lake
The lake surface is bounded by Songmen Mountain, which is divided into two parts: north and south. The south is wide. It is the main lake area. Large and long, in order to enter the river water channel, 40 kilometers long, about 2.8 kilometers of the narrowest part, and the lake is deep;

The lake water supply mainly includes the Gan River, Fuhe, Xinjiang, Raohe, Xiuhe, Boyang River, and Boyang River and After the Western River, after the transfer, it was injected into the Yangtze River from Hukou to the north. The amount of water flowing into the Yangtze River has an average of 146 billion cubic meters on average for many years, exceeding the sum of the water volume of yellow, Huai, and Hai. The area of ​​Poyang Lake Water system is 16.22 million km2, accounting for about 97%of the Jiangxi province's basin area, accounting for 9%of the Yangtze River basin area: its average annual runoff of the water system is 152.5 billion cubic meters, accounting for about 16.3%of the annual average runoff of the Yangtze River Basin. Essence

The Poyang Lake is a huge throughput -type lake in seasonal changes. The difference between the area and the water storage volume during the flood and dry period. The water level changed from 9.79 to 15.36 meters during the year, and the absolute water level changed by 16.69 meters. Every spring and summer, the lake is soaring, the water surface expands rapidly, and the smoke is vast; but in the winter, the lake drama falls, the containing beach is exposed, and only a few winding water channels are left on the lake. Form the landscape of "flood and dry water".

The average water level of 12.86 meters; the maximum water level 22.59 meters appeared (July 31, 1998), with an area of ​​4070 square kilometers and a water storage capacity of 30 billion cubic meters; the minimum water level appeared at 5.90 meters ( On February 6, 1963), the area was only 146 square kilometers and the water storage capacity was 450 million cubic meters.

The historical change
Puyang Lake was known as Peng Yeze, Peng Ze and Guan Ting Lake.

The ancient Peng Yizezawa's scope includes the Binjiang Lake District, such as the Yuanhuang Lake, Daguan Lake, and Pohu Lake on the east of Hubei on the north bank of the Yangtze River, connecting it with the Yangtze River water surface. At that time, the water area formed by the ancient Ganjiang River on the south bank of the Yangtze River was also connected with the Yangtze River Road Road, but the area of ​​the lake was very small, until the Qin and Han dynasties were still limited to the Poppy mouth (now Xingzi County, the ancient Ganjiang River in the ancient Ganjiang River during the Soochow Jin Dynasty Papering the narrow area north of Peng Yeze) to the north to the mouth of the lake. Because there is a pavilion temple next to the Poppy mouth, it is called Gongting Lake. In the late Western Han Dynasty, Peng Yeze and the Yangtze River were completely separated. The waters of the north of the Jiangbei gradually evolved into the waters of the river in the north of the river, while the Jiangnan waters gradually expanded and evolved into today's Poyang Lake. Because Ban Gu had the words "Yuzhang County ... County 18: ... Peng Ze, Peng Zezawa in the West" in "Hanshu Geography".

For the change of the name of "Peng Yeze", scholars have different views. Refers to the riverside waters, Ban Gu's theory is the attached words; some think that the ancient Pengli Ze is across the Yangtze River, including the Jiangnan waters, and today Poyang Lake is a disintegration and evolution of Gu Pengyu.

In the Han Dynasty, the current vast Poyang Lake waters are the downstream plains of the Lakes and Han (now Ganjiang). The Han Dynasty set up Yangxian here, and the king of Hanchangyi was also here. At that time, the main road of the Yangtze River was in the area of ​​Jinlong Lake today, and only the Yangtze River Road north of Lushan was called Xiaojiang. Around 400 AD, in the late East and Jin dynasties, the main road of the Yangtze River has moved to the area of ​​Jiujiang-Hukou. Jiangshui not only blocked the drainage of the Ganjiang River, but also poured into the lower reaches of the Ganjiang River, and gradually formed Poyang Lake. By the time of the Tang Dynasty, Poyang Lake had the largest area of ​​6,000 square kilometers.

Prior to invasion of Poyang Lake, the low -lying Poyang Basin was originally a dense town of people. With the continuous invasion of the lake, Poyang County and Haixun County in the Poyang Lake Basin have been flooded into the lake. In the middle, Wu Cheng, located in a higher high place in Haiyun County, has become one of the ancient towns of Da ancient town in Jiangxi. Therefore, in history, there was a saying "Haiyun County and Wucheng Town" in history.
