Ecological bank protection utilizes the interact of plant and rock, soil body to protect, consolidate the side slope top layer, makes it can satisfy the requirement stable on the side slope top layer, can resume the bank protection mode of destroyed natural ecological environment again, and at present, traditional ecological bank protection mainly has following three kinds:

1. and (3) protecting the stone cage slope: the engineering protective structure is mainly a box cage woven by high-zinc-plated steel wires or hot-dip aluminum-zinc alloy steel wires and an engineering protective structure made of non-weathered fillers such as stone materials and the like. The disadvantages are that: the problems of exposed grids, corrosion of metal, aging of plastic grids, alloy performance and the like, the local parts of the exposed grids are easy to damage, and loose stones in the grids are easy to fall out of the grids, so that the important factors influencing the safety of the slope protection are provided. In addition, the cut-off end of the metal and alloy grids is very sharp, and people who do hydrophilic activities and climb to save oneself are easily injured.

2. Slope protection of plant growth belt (bag): the non-woven fabric containing seeds and fertilizer is completely attached to a special PVC mesh bag, then planting soil is filled in the bag, and the non-woven fabric is piled up according to the shape of a mountain to realize greening. The disadvantages are that: when the fertilizer is used in a large area, plants grow slowly.

3. Plant growing matrix plant slope protection: after the anchor rod net is installed on the stable side slope, the mixture of rainwater of the helicopter material which is to be uniformly stirred is sprayed to the slope surface by using the special spraying of the helicopter, and plants grow and develop by relying on the plant growth matrix material to form the construction technology of plant slope protection. The basic structure is as follows: anchor (nail), net and plant growing matrix 3 part. The disadvantages are that: the construction technology is relatively difficult, and the engineering quantity is large; the thickness of the matrix material sprayed is thin, and the shell is easy to break off after being exposed to the sun; the thickness of the matrix material sprayed is thick, and if the weight of the matrix material is too large, the hanging net is easy to fall down.
