The purpose of the present invention is to provide an ecological restoration method for desertified land. This ecological restoration method can quickly and low-cost carry out ecological restoration in desert areas, improving the soil environment. The method involves creating grid areas by trenching in the desertified land, and filling the trenches with water retaining and sand fixing materials.
A woven mesh of plant plastic fibers is laid on top of the water retaining and sand fixing layer, and a plant protection layer is formed with a matrix composition mixed with sand plant seeds. Vertical plant fiber woven sand barriers are erected on both sides of the plant protection layer, and sand is backfilled to suppress the barriers. The size of the grid areas can be set according to the actual site. The beneficial effect of the invention is that its ecological restoration method forms a multi-layer windbreak and sand fixation structure by setting up a water retaining and sand fixing layer, a sand fixing mesh layer, and a plant protection layer from bottom to top, and setting up sand barriers on both sides of the multi-layer structure to form a three-dimensional protection, prevent the movement of sand and dust, prevent the land from continuing to desert, effectively improve soil water holding performance, improve soil particle structure, and restore desertified land to an ecological environment suitable for plant growth.
