Abstract

The invention discloses a restoration method of a half-exposed and half-submerged area in reservoir fluctuating zone steep gradient land and belongs to the technical field of ecological protection. The restoration method includes the steps: (1) when the water storing water level of a reservoir is lowest, it is selected to perform repairing and levelling, and clearing and punning on the steep gradient land of a fluctuating zone of the reservoir; and (2) paving of vegetation concrete is performed on the steep gradient land located in the half-exposed and half-submerged area: firstly, a supporting framework is paved on the slope face of the steep gradient land, fixing is performed through a ground anchor and an anchor rod, then after a vegetation concrete base material containing red clover seeds, cyperus rotundus seeds and hydrocotyle vulgaris seeds is stirred, spraying onto the slope face is performed through a spraying anchor, till a vegetation concrete layer wrapping the supporting framework is formed, after spraying is completed, the surface of the vegetation concrete layer is covered with non-woven fabric, then water sprinkling curing is performed till the slope face is coveredwith vegetation, and the non-woven fabric is removed for uncovering. Due to the restoration method, the half-exposed and half-submerged area in the reservoir fluctuating zone steep gradient land can be effectively restored, and the water and soil loss caused when a wet season and a dry season are alternating is reduced.

Description

technical field [0001] The invention belongs to the technical field of ecological protection, and in particular relates to a repair method for a half-exposed and half-flooded area in a steep slope of a reservoir drawdown zone. Background technique [0002] At present, the reservoir drawdown zone refers to a special area where the submerged land around the reservoir is periodically exposed to the water surface due to seasonal water level fluctuations. The reservoir ebb and flow zone forms a huge ecological isolation zone around the reservoir between the water body and the land bank in the reservoir area. It is a special water and land staggered wetland ecosystem. The periodic fluctuation of the water level will lead to soil erosion, vegetation destruction, geological disasters, etc. These hazards threaten the normal function of water conservancy and hydropower projects and the sustainable development of the ecosystem in the reservoir area. The ecological environment of the w...
