The invention discloses a stone side slope biological control method which comprises the following steps of (1) side slope status analysis and safety evaluation, (2) nursery stocks pre-cultivating, (3) bird nest type layout, (4) bionic nest building, (5) formula planting and (6) community forming. The stone side slope biological control method integrates the engineering mechanics, the ecology, the aesthetics, the biotechnology and other disciplines and fields, a stable and ecological three-dimensional side slope can be quickly formed, the landscape effect is good, the ecological benefit is lasting and stable, maintenance cost is low, maintenance difficulty is low, the slope fixing effect is obvious, a protection function is outstanding, and the method is used for side slope protection of roads, railways, dams and the like, and also can be used for ecological management of desertification and stony desertification.
