Embodiment 1

[0029] A construction method of river channel ecological restoration vegetation, said construction method comprising the following steps:

[0030] A. River Habitat Investigation: Conduct further investigations on the surrounding environment, soil environment and water level of the river to determine the ecological habits of the pre-selected aquatic plant species;

[0031] B. Screening of aquatic plants: When selecting plants, fully consider the complexity of the ecological factors of the river course and riparian zone, select plants suitable for the growth in the area, and diversify the plant species;

[0032] C. Planting submerged vegetation on the river course: In the whole area of ​​the project, submerged plants with strong pollution resistance are scattered and planted, such as hornwort, Hydrilla verticillum, Erythrina spp. , the combination of Erythrina genus or water shield grass, restore and rebuild submerged vegetation;

[0033] D. Plant waterfront plants on the river...

Abstract

The invention relates to a construction method for vegetation used for ecological restoration of rivers. The construction method mainly overcomes the problems of destroy of the ecological system of rivers, sharp decline in biodiversity, water pollution, decrease in water quality, etc. The objective of the invention is to carry out effective biodiversity restoration and water purification on riversthrough optimal cooperation between a plurality of terrestrial and aquatic vegetation. Thus, as the natural characteristics of rivers are restored, the ectone of terrestrial and aquatic vegetation can be restored, habitats can be provided for aquatic organisms, and the self-cleaning capability of rivers can be improved; so the construction method may become an important engineering measure for improving an aquatic ecosystem.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration engineering, and in particular relates to a method for constructing optimal vegetation in river courses, which is especially suitable for restoration and reconstruction of degraded river courses and riparian zone ecosystems of river courses. Use multi-faceted vegetation to restore biodiversity, purify water quality, and restore a healthy and stable river ecosystem. Background technique [0002] With the progress of society and the development of industrialization, the scale of cities continues to expand, the population increases, the rivers are heavily occupied, the ecology deteriorates, and the biodiversity and self-purification capacity of the rivers disappear. The river course is the ecotone of water and land, which has important functions in regulating climate, maintaining water and soil, and preventing floods. Human activities have changed the original hydrological balance and...
