Construction method of near natural mangrove forests at reef shallows

Abstract

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.

Description

technical field [0001] The invention relates to the field of mangrove planting, in particular to a method for constructing reef shoals near natural mangroves. Background technique [0002] Mangrove is a unique plant community on the beach at the junction of tropical and subtropical sea and land. It is dominated by mangrove plants and is inundated by periodic tides. It is an important vegetation type to maintain the balance of coastal ecosystems. , Consolidation of bank embankment and other functions. Land reclamation, land reclamation, and sewage discharge will all damage mangroves and reduce the area of ​​mangroves. These areas often suffer heavy losses in typhoons and tsunamis. Therefore, it is of great significance to effectively plant and restore mangroves in the beach belt for ecological protection. The existing artificial mangrove communities have poor ecological stability and are easily damaged, and each supply of seedlings needs to be purchased and transported over...
