Restoration method for damaged ecosystem in steep-slope area in water-level-fluctuating zone of reservoir

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.
