The invention relates to a slope water and soil conservation structure for ecological landscape restoration and a construction method thereof, and belongs to the field of slope protection. The slope water and soil conservation structure comprises brick bodies and connecting pipes; the brick bodies form a net-shaped structure through the connecting pipes, and the brick bodies are each of an H-shaped structure; connecting grooves are symmetrically formed in the left side faces and the right side faces of the brick bodies, and limiting holes are formed in the connecting grooves; the connecting pipes comprise main transverse pipes, vertical pipes and inserting pipes; the vertical pipes are evenly arranged on the same sides of the main transverse pipes and communicate with the main transverse pipes, and the inserting pipes are arranged on the two sides of the vertical pipes in a staggered mode; water leakage holes are formed in the inserting pipes, and the vertical pipes are arranged in the connecting grooves; and the inserting pipes are inserted in the limiting holes of the brick bodies, and ecological planting holes penetrating through the front faces and the back faces of the brick bodies are formed in the centers of the front faces of the H-shaped structures of the brick bodies. Through arrangement of the connecting pipes, the fixing effect between the brick bodies is improved, water can be replenished to vegetation through the connecting pipes, thus growth of the vegetation is facilitated, and the ecological landscape restoration effect is improved.
