Construction method for ecological restoration of riparian vegetation of mountain rivers

Abstract

The invention discloses a construction method for ecological restoration of riparian vegetation of mountain rivers. The method includes the following steps: (1), for restoration of aquatic vegetation, dispersedly planting potamogetonaceae and hydrocharitaceae submerged plants high in washing-out resistance in a project region; (2) for restoration of riverway rock and boulder vegetation, planting wetland plants strong in washing-out resistance in rock and boulder regions and the like in a riverway in the project region; (3) for restoration of waterfront plants, planting emerging plants and aquatic plants with washing-out resistance and deep roots between the riparian normal water level and the two-year flood level in the projection region; (4) for restoration of riparian vegetation, planting waterlogging-tolerance trees and shrubs of juglandaceae, betulaceae and the like between the two-year flood level and the 20-year flood level in the project region, and planting gramineae and cyperaceae herbaceous plants with deep roots in ground covers. By the method, the ecological problems about riparian water and soil erosion, weak river's self-purification capacity, sharp decline in biodiversity and the like are solved effectively, feasible and effective ecological remediation measures are provided for natural restoration and reconstruction of river banks and riverways.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration engineering, and in particular relates to an optimal construction method of river bank vegetation in mountainous rivers, which is especially suitable for the restoration and reconstruction of the ecological system in the degraded river bank zone. Use multi-level and multi-type vegetation to restore biodiversity, reduce pollutants, and restore a healthy and stable river ecosystem. Background technique [0002] In recent years, with the rapid increase of population and the development of industrial and agricultural production, the wetland ecosystem including the riparian zone has been seriously degraded due to the disturbance of human activities; therefore, the restoration of degraded ecosystem and restoration ecology have become the international ecology Hotspots in the research field. Foreign scholars have done a lot of research on the basis of experiments, but the theoretical and ...
