Revegetation system on steep rocky slopes and implementing method thereof

The invention discloses a revegetation system on steep rocky slopes and an implementing method thereof, which are suitable for surface vegetalization of steep rocky uncover slopes with the gradient of 60 degrees above. A slope drainage system is arranged in the system to prevent the vegetalization layer from being flushed by rainwater and reduce water loss and soil erosion; a mix-sprayed vegetalization layer plastic-covered with iron wire corrugated meshes and consisting of continuous fiber is arranged on the slopes and has stable structure, rich nutrition and functions of water conservation and ventilation. The casting separator prevents the mix-sprayed vegetalization layer from sliding downwards; and a drop irrigation facility is distributed to make sure that the vegetalization layer is moist. After maintenance of mix-sprayed construction on the slopes, the vegetable layer with herbaceous plants and shrubs can be effectively formed, thereby reconstructing the destructed vegetables on the slopes and recovering the natural landscapes on the uncover slopes.
