This plant is installed on the surface of rivers, lakes, lakes, ponds, and cuts to prevent the loss of slopes on rivers, lakes, hills, and cuts, and to protect and green the cover of water. The vegetation mat of the design includes a vegetation seed layer having a vegetation seed attached to its surface； A first protective layer (2) disposed below the vegetation seed layer to protect the vegetation seed layer, to make the vegetation mat have tensile strength, and to decompose over time； A vegetation seed nutrition moisture supply layer installed on the vegetation seed layer to provide moisture and moisturizing effects necessary for germination of the vegetation seeds and to supply nutrients of organic fertilizers； A second protective layer installed under the vegetation seed nutrient supply layer to serve as a vegetation foundation and to ensure structural stability and durability of the vegetation seed nutrient supply layer； A third protective layer installed on the vegetation seed nutrient supply layer to protect the vegetation seed nutrient supply layer and decompose over time； The upper reinforcing layer is installed on the third protective layer to prevent the stacked structure of the vegetation mat from detaching and to maintain the shape even after reaching a long time. According to the present invention, the vegetation mat composed of the first protective layer-vegetation seed layer-the second protective layer-vegetation seed nutrient supply layer-the third protective layer-upper reinforcement layer can be firmly fixed with an anchor to prevent departure from the ground. The vegetation mat made of biodegradable material after plant growth is naturally decomposed, and the anchor is also decomposed naturally over time, which can solve the fundamental problem of environmental pollution. The slopes are protected by the flow rate caused by flooding in the lakeside and the plants can be easily grown, so that muddy water and environmental hormones caused by problem
