The invention provides a river bank ecological restoration device and method suitable for mountain river characteristics. The device comprises ladder stone cages and a backfilling soil layer or ecological bags, wherein the ladder stone cages are arranged on the river bank slope, and the backfilling soil layer or the ecological bags are arranged in a gap between the ladder stone cages and a river bank. Grass seeds are spray-sown to form a grass seed layer after slurry is poured into the ladder stone cages; a rubble base layer is arranged at the bottoms of the ladder stone cages; riprap bankets are laid at the outer sides of the bottoms of the ladder stone cages; herbaceous plants are sown on the ecological bags; and herbaceous plants, shrubs and arbors are planted on the river bank at the upper portions of the ladder stone cages. According to the river bank ecological restoration device and method suitable for the mountain river characteristics, the cost is low, the operation is easy and convenient, and actions of stabilizing the river bank and providing a porous habitat for microorganisms and aquatic organisms are achieved; and the riparian zone environment suitable for the plants to grow is built to restore phytocenosis so as to intercept and absorb nonpoint source pollution loads coming from peripheral housing estates and farms, and therefore an action of protecting river water quality is achieved.
