The utility model discloses a composite protective structure for a reinforced net-plane stopping wall. The composite protective structure consists of a reinforced net-plane reverse wrapped soil engineering grating unit and a pre-stress anchor rod. The reinforced net-plane reverse wrapped soil engineering grating unit comprises a reinforced net plane, soil engineering gratings, a triangular supporting frame, soil engineering cloth and a plant growing pad. Compacted stuffing soil is arranged inside the reinforced net plane and on each soil engineering grating, and the soil engineering gratings of adjacent upper and lower units are provided with reliable connection. The reinforced net plane and an anchor head of the pre-stress anchor rod can be connected into a whole. The soil blocking wall has the advantages of high strength, excellent stability, reasonable stress, convenient construction, wide application scope, low construction cost, remarkable ecological and environment-protection performance and the like.
