The invention discloses a method for restoring vegetations in a water-level-fluctuating zone. The method is capable of effectively preventing and controlling water and
soil loss, intercepting and absorbing harmful chemical substances in a
water body, reducing
eutrophication of the
water body and rapidly afforesting the water-level-fluctuating zone, and has the functions of fixing soil and retaining banks. The method comprises the following steps: 1) preparing soil of a riverside slope surface in a fluctuating zone, finishing the fluctuating zone along the
contour line to form a step structure, and respectively digging a cuttage
ditch on various steps of the step structure; 2) using
nutrient soil to cover various cuttage ditches, inserting a plurality of living
branch wooden piles, and connecting the adjacent living
branch wooden piles on the same step by using a
rope to form a whole, wherein planting grooves are formed between two rows of living
branch wooden piles on the adjacent steps; 3) sequentially filling a lower mucky soil layer, a
water supply layer, an upper mucky soil layer and a
nutrient soil layer into the planting grooves from bottom to top so as to form a planting layer; and 4) respectively planting submerged plants, emergent aquatic plants and water-resistant tree shrubs in various planting grooves along the step structure from bottom to top, so that a three-dimensional
vegetation restoring space is formed.
