After the ecological blanket is directly paved on the foundation bank slope, the surface of the foundation bank slope is attached to/fused with the corresponding side surface (called as the outer side surface for short) of the ecological blanket. The ecological blanket is nailed on a basic slope by adopting the fixing nails, so that the ecological blanket is fixed, then a thin soil layer (not drawn) is covered on the ecological blanket (the slope part of the ecological blanket), and the thin soil layer covered on the ecological blanket is combined with the ecological blanket.

The ecological blanket may be of any suitable prior art. The seed layer is built in by the main body part being made of plant fiber (such as coconut palm) or plant body (such as wheat straw), the seed layer can be a mixture of planting matrix and seeds, or the seeds can be clamped in the plant fiber layer or attached to other suitable materials. And (3) properly irrigating and maintaining, germinating and growing seeds, and gradually forming vegetation. For example, the ecological blanket is sequentially provided with a fiber fabric layer 21, a reverse filtering layer 22, a seed layer 23 and a fiber layer 24 from top to bottom, wherein the fiber fabric layer (which can be a composite fiber fabric layer) mainly bears fluid force from the outside, so that the impact resistance of grass seeds in germination and later stages is ensured; the material of the reverse filtering layer is non-woven fabric, and other suitable forms can be adopted. For example, the non-woven fabric with loose or large meshes is used for facilitating the penetration of planting roots, the reverse filtering layer mainly plays a role in reverse filtering, and when water flow flushing is encountered, the loss of soil (or other growth matrixes), grass seeds, fertilizers and the like in the seed layer is prevented; the seed layer can adopt any suitable prior art, can be a mixture of plant growth matrix and seeds, the matrix can comprise soil, fertilizer, water-retaining agent and the like, the seeds of the seed layer can be various (for example, three to five) grass seeds, tree seeds can be arranged or not, and the seed layer can be specifically selected according to local actual conditions and construction requirements (for example, landscape design requirements); the fiber layer can be made of plant fiber, straw and other plant bodies, or composite fiber, and has the functions of fixing grass seeds, preventing grass seeds from falling off, preserving moisture and preserving heat.

The top (or lower part) 26 of the ecological blanket is laid flat on the top (top plane) of the foundation slope, extends horizontally outwards for a certain distance to form a horizontal section of the top of the ecological blanket, and is covered with a soil covering layer 16 with a certain thickness, which is firmly fixed, and the top surface of the soil covering layer can be used to form a top surface (a part of the top surface of the shore). The covering soil layer can be omitted, and other objects can be used for pressing/fixing the horizontal section at the top of the ecological blanket according to actual needs.

The horizontal section at the top of the ecological blanket can be fixed on the top plane of the basic side slope by using the fixing nails before the soil covering layer is arranged.
