The invention relates to a
restoration method for a damaged
ecosystem in a steep-slope area in a water-level-fluctuating zone of a reservoir. The method comprises the following steps:when the impounded
water level is at the lowest point, cleaning the upstream slope in the water-level-fluctuating zone, and manually tamping; digging planting holes at the top of the slope, and planting Chinese red pines and the like to form a multifunctional protective
forest belt; digging planting grooves and planting holes within the range of the water-level-fluctuating zone, laying jute
geotextile, planting vetiver within the range with the water-level-fluctuating depth of 2m to form a hedgerow; and mixedly planting vetiver and wire grass within the range with the water-level-fluctuating depth of 2-10m to form a combined
vegetation slope restoration belt. The protective
forest belt, the hedgerow and the combined
vegetation slope restoration belt form a three-dimensional restoration space together, thereby ensuring that plants can take roots and restore in the steep-slope area in the water-level-fluctuating zone. By restoring the
vegetation in large area, the invention effectively reduces the overland flow and the soil
erosion, and improves the
fertility and the properties of the soil, thereby restoring the damaged
ecosystem. The invention has the advantages of convenient construction and less investment, can not be easily damaged by water, and is applicable to the water-level-fluctuating zone of a reservoir with large water-level-fluctuating range and precipitous
topography.
