Dike refers to the flat land on both sides of the river, which is formed by long-term siltation. There is a natural dam between the dam and the river, which can naturally rise or fall with the change of water level. Ridge land is generally fertile, which is used to grow rice and other crops, and is an important part of agricultural development in China. At the same time, it also plays an important role in flood control and water conservancy, and is an important natural resource.

The formation of dikes is closely related to rivers and currents. Under the action of long-term river erosion and water scouring, sediment gradually accumulates along the river and forms a ridge. Because of the gentle slope and slow water flow, sediments can accumulate on the ridge. This natural process takes a long time and appropriate conditions, so the embankment is often a place with a long history, cultural value and natural landscape.

Dike is one of the important natural landscapes in China River Basin, and it is also an important carrier and symbol of ancient civilization in China. In different areas, the characteristics of dikes are different. Some embankments are surrounded by mountains, forming a unique ecosystem, while others gradually rise in economic development, such as Kunlun and Huaxia, and become important local agricultural bases and tourist attractions. In a word, dikes are an important part of natural resources, human landscape and economic development, and should be properly protected and managed.
