Problems solved by technology

First, coastal tidal flats suitable for planting mangroves along the south coast of Zhejiang Province in my country have been widely used by fishermen to cultivate shellfish (razor clams, clams, seaweed) and ponds to cultivate fish, shrimp and shellfish. Conventional mangrove planting methods It will occupy the breeding space of the breeders, and it is difficult for the breeders to change industries and jobs. Moreover, it is not only costly to deal with policies, but also difficult to implement
Second, the planting of mangroves in the intertidal zone is defined by the standard of inland deep forest planting, and the number of planting areas is measured with "canopy density" as the main measurement index, without considering the integrity of the mangrove ecosystem and the mangrove and biological resources (Fish, crab, shellfish, etc. growing in the area), birds and other ecological, economic and social comprehensive benefits
With "canopy density" as the basis for evaluating the mangrove forest, after the mangrove forest grows, the birds cannot find food and cannot settle. The ecosystem has few organisms due to the lack of tidal water space, and the economic benefits cannot be reflected. The coastal zone can only see A "green tree" has only a small amount of ecological benefits, no economic and social benefits, and the public does not support it
Third, whether it is the impact of highly permeable seawater or floating objects, it is not conducive to the survival of mangrove seedlings. Mangrove trees are planted in rows in forests, and the mortality rate of mangrove seedlings is high.

Embodiment 1

[0045] Step 1. Use a dredger to remove harmful weeds such as Spartina alterniflora and related structural debris in the mangrove area to be planted.

[0046] Step 2. Planning site selection and planting layout: In the southern waters of Zhejiang, the muddy or muddy tidal flat area in the intertidal wet zone of the ecological seawall; the rhombus ( figure 1 ), equilateral triangle ( figure 2 ), round ( image 3 ) Planting clusters of three shapes are arranged alternately along the intertidal wetland, each cluster is about 4cm 2 , the distance between each cluster is 30 meters, forming an orderly sea landscape planting belt, planting 30 clusters.

[0047]Step 3. Set up protective enclosures: according to the horizontal height of the intertidal wetlands in the southern sea area of ​​Zhejiang, build protective enclosures; protective enclosures include: solid soil enclosures and protective fences, solid enclosures for the Yellow Sea elevation The height of the net is 1m.

Abstract

The invention discloses a kandelia candel planting cluster forest belt for a mudflat mangrove forest in a high-stormy-wave strong-tide area. By controlling the planting density of planting clusters and spacing of the planting clusters and cooperating with a protective enclosure, the planting clusters can resist the impact of seawater and floaters within 1-2 years, the quantity of planktons and marine products in the tidal flat area is effectively increased, and habitats are provided for birds. A practical basis is provided for tidal flat reconstruction.

Description

technical field [0001] The invention belongs to the technical field of mangrove planting, and in particular relates to a method for planting candela in tidal flats in high wind, wave and strong tide areas. Background technique [0002] Mangrove (scientific name: Rhizophora apiculata BI.) is a tall tree belonging to the family Mangroveaceae, distributed in tropical Southeast Asia, Melanesia, Micronesia, northern Australia and China. It is often a small tree in China, 2-4 meters high, distributed in Guangdong and Hainan, and born in shallow sea salt flats with calm waves and soft silt or marshes in bays. [0003] Mangroves refer to tidal flat wetland woody communities that grow in the upper part of the intertidal zone of tropical and subtropical coasts and are flooded by periodic tides. Mangrove wetlands are mainly composed of evergreen shrubs or trees. Wetland types have been included in my country's coastal wetland classification system. Mangroves are a special ecosystem in...
