Embodiment 1

[0023] A method for constructing Huaihe river course ecological restoration vegetation, the steps are:

[0024] 1. Habitat investigation of the Huaihe River channel: First, the applicant conducts further investigations on the surrounding environment, soil environment, and water level of the Huaihe River channel to determine whether the ecological habits of the pre-selected aquatic plant species meet the conditions.

[0025] 2. Screening of aquatic plants: When selecting plants, fully consider the complexity of the ecological factors of the Huaihe River channel and riparian zone, select plants suitable for the local growth, and diversify the plant species as much as possible. Although there are many kinds of aquatic plants, they should not be abused. In addition, it is necessary to avoid too much pursuit of new, strange, exotic and rare varieties in the selection of plant species, otherwise it will affect the species composition of the local waterfront vegetation community, des...

Abstract

The invention discloses a method for building river course ecological restoration vegetation. The method comprises the following steps of: (1) restoring submerged vegetation: planting submerged plants with high pollution resistibility such as hornworts, hydrilla verticillata and the like in an entire engineering region in a dispersed way to restore and rebuild submerged vegetation; (2) planting riparian plants: planting emergent aquatic plants and rooted floating plants such as meadow rush, scirpus yagara, scirpus tabernaemontani, thalia dealbata, calamus, cattail, rumex dentatus, ranunculus sceleratus, water-garden iris, monochoria korsakowii and the like respectively on river sloping banks in the entire engineering region to restore and rebuild a sloping bank and riparian emergent aquatic plant community; and (3) restoring flood land vegetation: comprehensively restoring flood land vegetation such as reed, cyperus glomeratus, wire grass, festuca elata, dallas grass and the like in the entire engineering region except a part of building land. Due to the adoption of the method, the ecological problems of pollution and degeneration of river course water quality, poor river self-cleaning capacity, sharp fall in biodiversity and the like are solved effectively, and a practicable and effective ecological restoration measure is provided for natural restoration and rebuilding of a river course.

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 the Huaihe River channel, which is especially suitable for restoring and rebuilding the degraded channel of the channel and the ecological system of the riparian zone. 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 hydrolog...
