Problems solved by technology

This method greatly disturbs the ecological environment of coastal wetlands, and the cost is high, and it is easily affected severely during the typhoon season, so it is not suitable for large-scale construction of native mangroves; heavily polluted water bodies will affect the survival rate of mangroves

Embodiment 1

[0024] According to the urban sewage standard (lead 1mg / L, zinc 5mg / L, copper 2mg / L, total nitrogen 2mg / L, total phosphorus 0.4mg / L), select 1-2 year old seedlings with a removal rate of more than 50% of the standard urban sewage Seedlings of candela and oleracea.

[0025] On the light beach of the unsuitable forest land in Xianlai Village, Chengcheng Town, Zhanjiang Prefecture, select an arc-shaped area along the coastline with a length of 2000m and a maximum width of 800m. Plant and build 15-20 meters wide annular sea sangria 1-year-old or 2-year-old Laguana seedlings on the tidal flats with 17,300 plants, with a height of 40-70 cm. Use ropes to tie the seedlings to bamboo poles (deeply inserted 60-70 cm below the soil) Above, the spacing between plants and rows is about 1.5m×1.5m, and it will be 2-3 years after the saplings (survival) are planted. A total of 643,400 2-year-old candela seedlings and olive tree seedlings of local species were placed in the open space in the ...

Abstract

The invention discloses a construction and building method of an anti-pollution mangrove forest protection forest. The construction and building method comprises the following steps that 1-2-year seedling mangrove plant species with the standard municipal sewage rate being more than 50% are selected according to municipal sewage standards; annular pagatpat annual or laguncularia racemosa biennial seedling forest zone with the width being 15m-20m is planted and constructed on mudflats which have more serious offshore pollution and great storms and are unsuitable for afforestation; after a pagatpat or laguncularia racemosa forest is planted for 2-3 years, the mangrove plant species are planted in a space in an offshore annular zone with the width being 15m-20m; the plant spacing and the row spacing for planting pagatpat or laguncularia racemosa are 1m-2m and 1m-2m respectively; the plant spacing of planting a local mangrove forest is 0.5m-1m and the row spacing is 0.5m-1m. According to the construction and building method, the mangrove forest is built on the mudflats which have more serious offshore pollution and great storms and are unsuitable for afforestation, so that the local mangrove forest can be built while exotic species are planted; the landscape ecology is coordinated and the species are diversified and abundant; the mangrove forest is high in survival rate and has good anti-pollution and anti-storm performances.

Description

Technical field: [0001] The invention belongs to the field of afforestation on coastal estuaries and bays where the pollution is relatively serious (inorganic nitrogen, heavy metal pollution), the wind and waves are large, and the area is not suitable for forestation. Background technique: [0002] Mangrove wetlands are generally located in the sea-land transition zone, mainly concentrated on the coastal intertidal tidal flats that are periodically flooded by seawater. It is a wetland ecosystem at the edge of the sea and land formed by the joint action of the atmospheric system, land system and water system. Unique hydrological, biogeochemical and ecological functions. Mangroves are one of the four most productive marine ecosystems in the world and play an irreplaceable and important role in the global ecological balance. In recent years, due to factors such as population pressure and economic development, man-made destruction and increased pollution have occurred in coasta...
