Abstract

The invention discloses a method for constructing a mangrove forest on an offshore river bank. The method comprises the following steps of establishing a temporary cofferdam on the edge of the offshore river bank, excavating earthwork of the offshore river bank, reducing the elevation of the offshore river bank to form a planting slope, and dividing a mangrove pre-planting area and a semi-mangrovepre-planting area according to a first highest tide level line; improving the soil of the mangrove pre-planting area, and improving or replacing the soil of the semi-mangrove pre-planting area; laying an anti-scouring blanket on the slope surface of the planting slope; removing the temporary cofferdam, measuring to obtain a second highest tide level line, and dividing a mangrove planting area anda semi-mangrove planting area according to the second highest tide level line. According to the method disclosed by the invention, the planting slope is formed by reducing the elevation of the offshore river bank, and the soil on the planting slope is improved or replaced so as to be suitable for the growth of mangrove forest plants and semi-mangrove forest plants. The method not only aims at mudflat reconstruction, but also is wide in application range, capable of effectively increasing the distribution area of the mangrove forest, improving the forest stand quality, and improving the ecological value and landscape value of the offshore riverway.

Description

technical field [0001] The invention relates to a method for building mangroves in the technical field of mangroves planting near the sea. Background technique [0002] Mangrove is a tidal wetland woody biome composed of evergreen shrubs or trees mainly composed of mangrove plants, which grows in the upper part of the intertidal zone of tropical and subtropical coasts and is inundated by periodic tides. Wind and wave impact, protection of farmland and reduction of salt damage all play an important role. Due to human disturbance, seawater pollution and other reasons, the distribution area of ​​mangroves in my country has been greatly reduced, and the quality of forests has declined, which seriously threatens the ecological security of coastal cities. [0003] Existing techniques for mangrove artificially construct mangrove forests, all of which are to transform the tidal flats of seaside or coastal rivers, and then plant mangrove plants to construct mangrove forests, which s...
