Ecological rehabilitation method and system of gully of plateau, swamp or wetland

The invention provides an ecological rehabilitation method and system of a gully of a plateau, a swamp or a wetland, and relates to the technical field of ecological rehabilitation. The ecological rehabilitation method comprises the following steps that the gradient of different gully sections and the flowing speed of water body of the gully of the plateau, the swamp or the wetland are measured first; and then different buffering dams are built at different gully sections according to the gradient and the flowing speed of the water body of the different gully sections, and the technical problem that novel erosion is formed due to the fact that water and soil loss on two sides of dam bodies or in a gully aggravates due to the fact that the water body passes around from the lateral sides orcontinues to perform down-cutting from the bottoms of the dams when the gully of the plateau, the swamp or the wetland is rehabilitated by an existing earth-stone-bag dam building method and a concrete dam building method is
