Mangrove is a woody plant community that grows on tropical and subtropical coasts and intertidal zones of estuary and plays an important ecological role in coastal areas. However, the mangrove forest community is seriously damaged because the living beach environment is polluted to different degrees and artificially interfered. In order to protect mangrove resources and develop a coastal beach protection forest system, the national forestry bureau wetland department proposes that in the year of 2020 plus 2023, China needs to plant forestation and reseed mangrove 1.8 ten thousand hm2. But the current mangrove afforestation and species-replenishing and planting-benefiting areas in China are extremely short. The scholars do research and pilot from the perspective of returning to forest from the pond and have certain effect. But the early investment is large, the effect is slow, and the planting area of mangrove forest can not be effectively increased.
The adoption of cofferdams for field building and mangrove forest planting needs a large amount of investment and causes serious damage to coastal ecology.

(2) after the artificial cultivation of the forest belt at the front edge is successful, the tidal scouring can be effectively slowed down, the sand sinking of the tidal flat behind the forest belt is accelerated, the forest belt range is widened, the rapid natural forest establishment of the mangrove forest can be promoted, and the rapid sea expansion of the tidal flat of the mangrove forest is promoted;
(3) the method of the invention can enhance the tidal scour resistance of the mangrove forest belt.
(4) The method of the invention is adopted to manually construct the soft shelter forest belt in front of the seawall, which can accelerate the siltation of the tidal flat in front of the seawall, form the tidal flat suitable for the growth and development of mangrove plants, increase the forest comforting area of the mangrove, effectively slow down the erosion of the seawall by sea waves, protect the seawall, promote the sediment deposition in the sea water, purify the sea water, improve the ecological environment of the coastal zone and build a blue bay.
