| description | An artificial fish spawning site with a variable water return zone of a reservoir comprises a bank slope, and the bank slope is provided with a slope top and a slope bottom; a driving vehicle body is arranged on the slope top and used for moving on the slope top in the upstream and downstream direction. A connecting plate is arranged on one side of the driving vehicle body and is in a cantilever shape, and the cantilever end of the connecting plate horizontally extends to the position above the slope bottom. A plurality of vertical shafts are arranged at the cantilever end of the connecting plate, and the lower ends of the vertical shafts extend downwards into a river channel water body; each vertical shaft is provided with a substrate disc, and substrates used for spawning and breeding of fishes are arranged in the substrate discs. When the running water level of the reservoir changes, the length of the backwater change zone of the main branch of the reservoir area changes, so that the active vehicle body ca |
