Where did today s Panyang Lake belong in the Western Han Dynasty

Poyang Lake was known as Peng Lize, Peng Ze and Guanting Lake in ancient times. In ancient times, the area of Peng Lize roughly included the source lake in the east of Hubei on the north bank of the Yangtze River, Longgan Lake, Daguan Lake and Bo Lake in the west of Anhui, and other riverside lake areas, which were connected with the water surface of the Yangtze River. At that time, the water area formed by the confluence of the ancient Ganjiang River on the south bank of the Yangtze River was also connected with the Yangtze River at the mouth of the lake, but the lake area was very small, until the Qin and Han dynasties, it was still limited to the narrow strip north of the poppy mouth (now Xingzi County, the intersection of the ancient Ganjiang River flowing into Peng Lize in the Eastern Wu and Jin Dynasties) to the mouth of the lake, because there is a palace pavilion temple next to the poppy mouth, so it is called Gongting Lake.

In the late Western Han Dynasty, Peng Lize was completely separated from the Yangtze River, and the waters of Jiangbei gradually evolved into today's Jiangbei Lakes, while the waters of Jiangnan gradually expanded and evolved into today's Poyang Lake. Because Ban Gu has "Yuzhang County...... in the "Hanshu Geographical Chronicles".County XVIII: ......Peng Ze, "Yu Gong" Peng Lize is in the West", and then "Peng Lize" refers to Poyang Lake.

Scholars have different views on the change of the name of "Peng Lize", and some rely on the "Daoyang...... contained in "Shangshu Yugong".Donghui Ze is Peng Li", which believes that the ancient Peng Lize only refers to the waters of Jiangbei, and Ban Guzhi is a supplementary statement; Some people believe that the ancient Peng Lize land spans both sides of the Yangtze River, including the waters south of the Yangtze River, and the current Poyang Lake is the disintegration and evolution of the ancient Peng Lize. In the Han Dynasty, the vast waters of Poyang Lake were the lower reaches of the Hanshui Lake (now the Ganjiang River), where the Han Dynasty set up a county and the fief of the king of Changyi of the Han Dynasty. At that time, the main road of the Yangtze River was in the area of Longgan Lake today, and only the Yangtze River was a road north of Lushan, which was called Xiaojiang at that time.

Around 400 A.D., that is, in the late Eastern Jin Dynasty, the main Hongdao of the Yangtze River moved to the area of Jiujiang-Hukou. The river water not only blocked the drainage of the Ganjiang River, but also poured into the lower plains of the Ganjiang River, and gradually formed Poyang Lake. By the height of the Tang Dynasty, the maximum area of Poyang Lake reached 6,000 square kilometers.

Before the southward invasion of Poyang Lake, the low-lying Poyang Basin was originally a densely populated town, with the continuous southward invasion of the lake, Poyang County and Haiyang County in the Poyang Lake Basin were successively flooded into the lake, and Wucheng, which is located in the vicinity of Haiyang County, has become one of the great ancient towns in Jiangxi Province day by day.

Near Yuzhang County, it should be.

Panyang Lake is located in Jiangxi Province, with an area of 3,150 square kilometers at a flat water level (14 meters and 15 meters) and more than 4,125 square kilometers at a high water level (20 meters). But at low water (12 meters) it is only 500 square kilometers.

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. 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.

Poyang Lake (not Panyang Lake) is located on the south bank of the middle reaches of the Yangtze River between Jiujiang and Nanchang in the north of Jiangxi Province. Accounting for the land area of the province, the main one is Nanchang City.
