The invention provides a
riparian zone ecological restoration
system and a construction method thereof. The
riparian zone ecological restoration
system comprises a riverway slope protection structureand a riverway structure which are adjacently connected. The river slope protection structure comprises an original soil tamping layer, a first coarse sand
cushion layer, an anti-seepage
blanket layer, a second coarse sand
cushion layer, a geotechnical cloth layer, an ecological
gabion layer, a planting soil layer and an anti-scouring
blanket layer which are sequentially arranged from bottom to top in the height direction of the slope surface of a side slope; a planting groove is formed in the junction of the slope surface of a river slope and a river, and submerged plants are planted in the planting groove; and the first coarse sand
cushion layer, the anti-seepage
blanket layer, the second coarse sand cushion layer, the geotechnical cloth layer, the ecological
gabion layer and the anti-scouring blanket layer extend into a river channel from the slope surface of the side slope through the planting groove. According to the
system, through the combination of ecological gabions, anti-seepage blankets and anti-scouring blankets, the stability of a river
bank is guaranteed on the premise of meeting the requirements of
flood discharge and flood drainage, and water and
soil loss can be favorably prevented; and the submerged plants are planted in the planting groove, so that the restoration of the
ecological environment of a
water body is facilitated.
