Method for constructing and creating mangrove protection forest on mud flat non-suitable for frosts

Abstract

The invention belongs to the technical field of creating frosts on coastal subtidal zone mud flat non-suitable for forests and in particular relates to a method for constructing and creating a mangrove protection forest on a mud flat non-suitable for frosts. The method comprises the following steps: (1) manufacturing culture tanks; (2) arranging the culture tanks, namely taking a lowest water level line where a coast land suitable for forests extends to an ocean as a reference line, setting a part at an elevation of 0.30m on the lowest water level line in an area of the land suitable for forests as an outer line of the land suitable for forests, arranging the culture tanks on a mud flat non-suitable for forests parallel to the outer line of the land suitable for forests, and exposing the top surfaces of the culture tanks outside the water level of a subtidal zone, wherein the top surfaces are 10cm higher than the elevation of the outer line of the land suitable for forests; and (3) filling the culture tanks with soil taken outside a tidal flat till the filling height is parallel to the elevation of the outer line of the land suitable for forests, and planting grown trees and seedlings of a mangrove forest in the culture tanks, or performing inter-cut on mangrove forest plant embryos in the culture tanks. By adopting the method provided by the invention, the mangrove forest is cultured in the subtidal zone of the front edge of a belt suitable for forests, wave prevention and siltation promotion can be achieved, the planting area of the mangrove forest can be increased to themaximum extent, the forest creation cost can be lowered, and the ecological benefits of a littoral environment can be increased.

Description

【Technical field】

[0001] The invention relates to the technical field of afforestation and sedimentation promotion on tidal flats in subtidal zones, in particular to a method for constructing and building mangrove protection forests on unsuitable tidal flats. 【Background technique】

[0002] The seawall has been washed by waves for a long time, the structure of the embankment is damaged, the foundation of the embankment is hollowed out and damaged, and the seawall is prone to collapse, which seriously threatens the personal and property safety of coastal residents; , resulting in turbidity and poor water quality in coastal waters, severe damage to the ecological environment of coastal waters, a serious shortage of mangrove resources, and a small area of ​​mangrove forest land, which is far from meeting the needs of self-purification of the coastal ecological environment.

[0003] Mangroves are woody plant communities that grow in the intertidal zone of tropical and subtropica...
