According to the main structure and function of the ecological corridor, the ecological corridor can be divided into a linear ecological corridor, a belt-shaped ecological corridor and a river corridor.
The river corridor is one of ecological corridors, is a core component of a basin ecosystem, and is also a main bearing body for various interferences generated by human social and economic activities in the basin range. The river gallery is composed of a river channel, a river flood land and an edge transition zone, and can also be divided into the river channel, the river flood land, a side slope, a river bank and a part of high land.
