Introduction Chongming Island is located at the junction of the river and the sea. The sediment discharged from the Yangtze River forms a huge mudflat around the island, which is the unique advantage of Chongming. From 1956 to 1984, Chongming Island reclaimed a total of 612560.7 acres of land. In 1984, there were more than 420000 mu of mudflat with a height of more than 0 meters, including 205500 mu with an elevation of more than 2 meters in Wusong, 136000 mu with an elevation of more than 3.2 meters, and more than 80000 mu with an elevation of more than 3.6 meters and reclamation conditions. Sediment siltation is rapid in the north and east, and the mudflat area is large. Animals and plants such as Shihuang (native chicken), Wedelia chinensis, Phragmites australis, Guancao, Silk Grass, and Arundinaria australis grow on the mudflat, and there are abundant biological resources In the rustling reed marshes, amidst the vast expanse of water, clusters of emerald green gather. The emerald green is poplar, the green is willow, and the arrow piercing towards the blue sky is the water fir. What is the willow tree blocking? It is a longing for the great river, a bitter love for the long embankment, a loyalty to the homeland behind the embankment, and a direct face to the fierce winds and waves The golden mudflat of Chongming Island has a variety of customs. It's worth a visit.
