いて実施する場合にもきわめて有効である。As described above, according to the first aspect of the present invention, greening of the entire slope can be promoted by forming a vegetation base of herbs having mainly water resistance on the slope. For example, the present invention is extremely effective when the method is applied to a rock-shaped slope such as a dam lake.

At the same time, and at the time of exposure, a multi-function can be exhibited to prevent plant growth disorders.

Nonwoven fabric and porous mats that wrap the vegetation base material on which vegetation is planted, especially the porous mat exerts a very large buffering action against water flow and waves when the water is full, and the vegetation base material in the greening basket flows out To prevent the growth of plants by exhibiting multiple functions during exposure.

改良も容易できわめて経済的である。In particular, the second invention is a structure in which a plurality of greening baskets in which tree seedlings are planted are attached and fixed to the slope, and the number and positions of the greening baskets are appropriately selected. This makes it possible to adjust the density of the greening restoration, to facilitate replenishment after construction, and to easily repair and improve the cost, which is very economical.

きわめて効果的である。Furthermore, the third invention has both the effects of the first invention and the effects of the second invention. Not only is the entire slope slope greened mainly by water-resistant herbs. By planting mainly water-resistant woody plants in greenery baskets attached to the surface of the slope, the slope at the time of exposure can be reconstructed in harmony with the natural environment,
This is extremely effective, especially when installing on rocky slopes such as dam lakes.
