The gravel layer can be laid on the soil covering surface, the leveling layer is laid on the gravel layer, the leveling layer is leveled and compacted by sand, then the water permeable bricks are laid on the leveling layer, the water permeable bricks are tamped and leveled, the water permeable bricks are convenient to walk, and the rainwater can be rapidly infiltrated.

The soil material that forms is mixed to the soil body, fine sand and humus around packing into to planting the groove 25, then plants the plant in planting the groove 25, mixes the soil material and becomes vegetation and provides necessary nutrient, and the root system of the plant of being convenient for pricks steadily, and the plant equidistance distributes, has beautified the environment, avoids the bald, the hardening of ground, and the plant can play and block the effect, slows down the velocity of flow of ground runoff, reduces the scouring action of rainwater.

The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve the same technical problems and achieve the same technical effects are within the scope of the present invention.
