Coastal intertidal zone ecological restoration system and construction method thereof

Abstract

The invention discloses a coastal intertidal zone ecological restoration system and a construction method thereof, relates to the technical field of coastal ecological restoration, and aims to solve the technical problems that water and soil loss is serious due to erosion of stormy waves during fluctuation and ebb tide, planted seedlings cannot be planted due to serious erosion of plant planting surfaces, and the survival rate is greatly reduced in the prior art. According to the coastal intertidal zone ecological restoration system and the construction method thereof, geotechnical cloth for preventing water and soil loss is laid at the bottom of a planting area, geocells and timber piles are assembled in the intertidal zone green planting area during ebb tide, the geocells are backfilled with planting soil, and the outer side edges are built into retaining walls for retaining water and soil through ecological bags. A gravel layer which is resistant to moisture and water scouring and has the particle size of 3-5 cm is laid on the surface layer of the planting area, and mangrove plants and aquatic plants which are resistant to scouring and salt and alkali are planted in the greening planting area to jointly act to construct a storm-resistant planting system, so that the survival rate of nursery stocks is increased, and the aim of ecological restoration of the coastal coast is achieved.

Description

technical field [0001] The invention relates to the technical field of coastal ecological restoration, in particular to a coastal intertidal zone ecological restoration system and a construction method thereof. Background technique [0002] The so-called intertidal zone refers to the coast between the highest tide level and the lowest tide level during the spring tide period, that is, the range from the submerged place when the sea water rises to the highest level to the surface when the tide recedes to the lowest level. Above the intertidal zone, the coast where the water droplets of the waves can reach is called the supratidal zone; below the intertidal zone, the zone extending to the sea to a depth of about 30 meters is called the subtidal zone. [0003] With the emergence of problems such as environmental pollution and tension between man and land, the natural environment and ecosystems of the islands have been greatly threatened and destroyed, resulting in the reduction...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a coastal intertidal zone ecological restoration system and its construction method, which can effectively improve the survival rate of planted seedlings in the coastal intertidal zone, so as to solve the problem of soil erosion caused by the erosion of wind and waves during the ebb and flow of the prior art Seriously, the planting surface has been severely scoured, resulting in the failure of planting seedlings, and a technical problem that greatly reduces the survival rate
