The present application belongs to the technical field of saline soil slope protection, and relates to an ecological slope protection structure of soybean enzyme-vegetation-anti-slide pile combined reinforcement of saline soil slope and a construction method thereof. The ecological slope protection structure comprises a vegetation layer, a soybean enzyme solidified coarse particle layer, a vegetation base layer, a soybean enzyme solidified fine particle layer, a gravel layer, an anti-slide pile and a saline soil slope body. The anti-slide pile passes through the soybean enzyme solidified coarse particle layer, the vegetation base layer and the soybean enzyme solidified fine particle layer from top to bottom in sequence, and is longitudinally embedded in the bearing layer of the saline soil slope body. The vegetation layer is formed by sowing plant seeds on the surface of the soybean enzyme solidified coarse particle layer and the growth of the plant seeds in the vegetation base layer. The anti-slide pile is nested with each soil layer, and is supplemented by the anchoring effect of the vegetation roots to form an overall frame structure slope protection system. The present application provides a saline soil slope ecological slope protection structure with reasonable structural mechanical properties, good integrity, impermeability, salt isolation capacity and conformity with the ecological development concept.
