The invention discloses a construction method of near natural
mangrove forests at
reef shallows. Three
layers of cofferdams sequentially including a first
cofferdam, a second
cofferdam and a third
cofferdam are arranged, wherein the first cofferdam is formed through piling of hollow wave resistant blocks, and
mangrove plants are planted; a pioneer
protection layer is between the first cofferdam and the second cofferdam, a near
natural recovery layer is between the second cofferdam and the third cofferdam, and local
mangrove forest plants are planted; and a
seedling supply layer is in the thirdcofferdam. According to the construction method of near natural mangrove forests at
reef shallows, the pioneer
protection layer is arranged outside, so that the effects of preventing wind and preventing
waves can be achieved, destruction of the wind and the
waves to the near
natural recovery layer is decreased, and planting of the local mangrove forest plants in the near
natural recovery layer isfacilitated; mangrove plantlets are cultivated in the
seedling supply layer, and seedlings can be voluntarily and continuously supplied to the near natural
recovery layer, so that long distance purchase and transportation of
seedling sources can be avoided, and the production cost can be reduced; and three
layers are divided, so that
ecological stability and
species diversity of mangrove forest communities are increased. The construction method disclosed by the invention is used for the field of mangrove forest planting.
