The North China Plain is mainly formed by alluvial deposits of the Yellow River, Haihe River, Huaihe River and Luanhe River. The lower reaches of the Yellow River naturally cross the middle and are divided into two parts: north and south. Huanghuai Plain in the south and Haihe Plain in the north. /kloc-over the past 0/00 years, the Yellow River has reclaimed 2,300 square kilometers of land here. The plain continues to extend to the ocean, with the Yellow River Delta as the fastest, averaging 2-3 kilometers per year.
Extended data:
The North China Plain is a Cenozoic fault depression area on the North China Platform. In the Late Tertiary and Quaternary, the adjacent great plains were formed, and at the same time, the fault blocks at the edge of the plains rose relatively, and the outline of the great plains became increasingly clear. The Cenozoic era sank relatively and received thick deposits, with local deposits reaching several kilometers.
North China Plain is less than 100 meters above sea level, and the terrain is gentle and inclined. From the foothills to the seaside, there are several landform types, such as alluvial inclined plain, alluvial fan plain, alluvial plain, alluvial lacustrine plain, marine plain and marine plain. The landforms shaped by rivers such as the Yellow River, Haihe River and Luanhe River constitute the main body of the North China Plain, namely the Yellow River alluvial fan plain; Plain in the middle and lower reaches of Huaihe River; Plain in the middle and lower reaches of Haihe River; The alluvial fan plain in the lower reaches of Luanhe River.
