The utility model discloses a coastal
salt marsh land ecological restoration structure which comprises a
saline-
alkali soil layer, a drainage blind
ditch is arranged on the
saline-
alkali soil layer, and a cobblestone layer is arranged in the drainage blind
ditch. The
saline-
alkali soil layer is covered with the planting layer, the planting layer is arranged in a
wave shape, a plurality of planting holes are formed in the planting layer, plants are planted in the planting holes, isolation
layers are arranged between the plants and the planting holes, drainage channels are arranged below the planting holes, through holes are formed in the drainage channels, and the isolation
layers and the drainage channels are communicated through the through holes; the blind
pipe is arranged below the
wave trough of the wavy planting layer, a first
water pipe is arranged on the blind
pipe, reverse filter geotechnical cloth is arranged between an opening of the first
water pipe and the planting layer, and the blind
pipe is connected with the drainage channel through a second
water pipe. Compared with the prior art, the saline-alkali water can be prevented from
backtracking, the
survival rate of
plant planting is improved, and ecological restoration of the coastal
salt marsh desert land is facilitated.
