Ecological restoration method of wet land

Abstract

The invention discloses an ecological restoration method of a wet land. A wetland plant community is built by planting hygrophilous wood plants in a lakeside zone, the hygrophilous wood plants comprise hygrophilous trees and hygrophilous shrubs, wherein the hygrophilous trees comprise willow, metasequoia, ascendens mucronatum, taxodium ascendens and bamboo; the hygrophilous shrubs comprise itea yunnanensis and salix integra thunb; and cutting with cutting seedlings or transplantation with soil ball seedlings is adopted for planting. Because the hygrophilous wood plants are perennial plants, the growth rate is low, the biomass and growth are small, cutting and fishing are not needed every year, and the pressure in disposing plants is small, so the defects that the herbaceous emerging plant community is reaped and fished every year is overcome, the maintenance management cost of a lake wet land plant community is lowered, the sediment accumulation rate of the lakeside zone is slowed and the potential problem of secondary pollution of the lake water is alleviated. Compared with the prior art, the invention has the characteristics of convenient operational maintenance and management, low maintenance cost, good ecological benefits, easy popularization and application and the like, and can be applied to ecological restoration works of lakeside shoal lands, swamps and shoal water zones.

Description

technical field [0001] The invention relates to a wetland ecological restoration method and the technical field of river ecological restoration. Background technique [0002] At present, there are many engineering practices for large-scale ecological restoration, but small-scale ecological restoration is rarely applied, and the current layout design of small-scale ecological restoration along straight rivers is mostly based on the statistical data of natural river bends. Empirical methods are used to determine the design parameters. Therefore, inventing a scientific and reasonable method for determining the layout of low-water ecological restoration projects in straight rivers has become an urgent task in the field of river ecological restoration technology. [0003] There are two main methods for ecological restoration of linearized rivers. The first is to carry out river ecological restoration on a large scale, that is, to transform the straightened river channel into a m...
