Reasons for the formation of Chongming Island.

Chongming Island is the product of the development of the new Yangtze River Delta, and its birthplace is the shallow sea outside the Yangtze River estuary. When the Yangtze River rushes eastward and flows into the estuary area, a large amount of sediment is gradually deposited here due to the decrease of the specific gradient and the slow flow rate. On the one hand, the coastal plain is formed on the north and south banks of the Yangtze River estuary, and on the other hand, scattered estuary sandbars are formed in the river channel. In this way, Chongming Island has gradually become a typical estuary sand island.

Extended data:

Chongming Island surfaced in the first year of Tang Wude (6 18), and two small sandbars were formed in the river, named Dongsha and Xisha. The residents came from Danyang, Jurong and other places in Jiangsu, with a history of 1300 years. In the first year of Shenlong in the Tang Dynasty (705), Chongming Town was established in Xisha.

In the third year of Tiansheng in the Northern Song Dynasty (1025), Yao continued to rise and bordered Dongsha. At the beginning of Jianzhong (1 10 1), Sansha rose more than 50 miles northwest of Yao. Thanks to fishing for salt, a God-given saltworks was established in the 15th year of Jiading in the Southern Song Dynasty (1222). The establishment and evolution, abolition and replacement of this period, the scale evolution of Chongming governance, and the relative lack of information. It was not until after the Yuan Dynasty that there was a record of "five relocations and six constructions".

Chongming Island today is formed by the accumulation of sediments from the Yangtze River. Because the Yangtze River carries a lot of silt, Chongming Island extends to the East China Sea at the speed of 1.43 meters every year, increasing the land by about 487 hectares.

Introduction of Chongming Island

It is adjacent to Qidong City, Jiangsu Province in the east, facing the East China Sea in the southeast, facing Pudong New Area, Baoshan District and Taicang City in the southwest, and facing Haimen City in Jiangsu Province in the north. Shaped like a spring silkworm, it is long from east to west and narrow from north to south. There are two islands beside Hengshan and Changxing. The formation of Chongming Island is related to the evolution of the Yangtze River estuary.

Because the Yangtze River Estuary extends to the southeast, and Koumensha Island tends to tilt northward continuously, the position and shape of Chongming Island are far from those of Chongming Island in the past. The current situation is that the beaches in the east and north of Chongming Island are still silting up, and the east beach is advancing to the East China Sea at the rate of 100 meters per year.

"Ecology" and "environmental protection" are the key words in the planning and construction of Chongming Island. Chongming Island is divided into two administrative regions, which belong to Nantong City, Jiangsu Province (later to Qidong and Haimen county-level cities) and Chongming District, Shanghai. But Qidong and Haimen are very small, so most people mistakenly think that the whole island belongs to Chongming District, which is wrong.
