Intertidal zone three-dimensional restoration method

Abstract

The invention provides an intertidal zone three-dimensional restoration method, and relates to the field of intertidal zone treatment. The intertidal zone three-dimensional restoration method comprises the following steps of mowing spartina alterniflora, and performing dam flooding to kill plants; conducting high tidal flat suaeda salsa repairing, using overground parts of the plants of the spartina alterniflora for arranging terrain, sowing suaeda salsa seeds on a shallow layer of a supratidal zone, and creating a micro-terrain to intercept the suaeda salsa seeds; conducting low-tide-level seaweed bed repairing, and treating a low-tide-beach seaweed bed degradation area; and conducting enhancement and releasing of benthic organism seedlings to restore mudflat benthic animals. By mowing and flooding the spartina alterniflora, the overground parts of the plants can be recovered and utilized through suaeda salsa, the benthic animals are recovered after high tidal flat suaeda salsa repairing and low tidal level seaweed bed repairing are conducted, three-dimensional repairing of an intertidal zone is completed, and the diversity of the intertidal zone is recovered.

Description

technical field [0001] The present disclosure relates to the field of intertidal zone management, in particular to a three-dimensional intertidal zone restoration method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Spartina alterniflora is the first invasive alien species to invade my country. The massive expansion of Spartina alterniflora has occupied the ecological niche of native native species. Spartina alterniflora competes with seagrass on low-tidal flats and competes with Suaeda alterniflora on mid-tidal flats. , and invaded the light beach of the potential distribution area of ​​Suaeda salsa. Therefore, the invasion of Spartina alterniflora threatened the survival of seagrass and Suaeda salsa in nature reserves at the same time. [0004] The biomass of Spartina alterniflora is relatively high, and it can produce a large amoun...

AI Technical Summary

Problems solved by technology

[0007] The inventor found that in the current Spartina alterniflora management process, the method of mowing and moving outside the range of the coastal wetland is often adopted, but because the root system of Spartina alterniflora is difficult to remove, it is still impossible to effectively eradicate Spartina alterniflora ; After the removal of Spartina alterniflora, the intertidal restoration method is single, and the re-growth Spartina alterniflora will still encroach on the environment of the restoration area, making it difficult to carry out the restoration work, the vegetation degradation in coastal wetlands cannot be effectively controlled, and the biodiversity is difficult. get restored
