Method for repairing coral reef area with broken reef disc and coral splicing table

Abstract

The invention discloses a method for repairing a coral reef area with a broken reef disc and a coral splicing table, and belongs to the technical field of ecological engineering tools. The method comprises the steps that the coral splicing table is put into a selected degradation area, the coral splicing table comprises a #-shaped main splicing table arranged at the top and supporting legs fixed to the lower portion of the main splicing table, and the supporting legs are inserted into the seabed; and binding the transplanted coral at a preset attachment site on the main splicing table so as to promote the coral to establish a three-dimensional structure. According to the method, coral splicing is utilized, the live coral coverage rate of a degraded reef area can be effectively increased, recovery of a coral reef ecological system is promoted, and the influence of resuspension of sediments on coral is effectively reduced; compared with other engineering repairing means, the coral platform splicing technology adopted by the method has the advantages that the unit area repairing cost is low, and the coral platform splicing technology is portable and easy to transport and carry; the coral splicing platform can be reliably fixed to the seabed and has a good in-situ repairing effect, and the survival rate and the growth rate of transplanted coral are high.

Description

technical field [0001] The invention relates to the technical field of ecological engineering tools in the field of coral reef ecological restoration, in particular to a method for restoring a fragmented coral reef area of ​​a reef disk and a coral assembly. Background technique [0002] Coral reef ecosystems have high biodiversity and primary productivity, and can provide people with a variety of ecological functions. [0003] Coral reefs have been subjected to destructive fishing methods such as blasting fish, poisoning fish, digging clam shells, and coral mining. In addition, the combined effects of coastal construction and typhoons have led to regional degradation of coral reefs, and many reef trays have three-dimensional structures. destruction and collapse. [0004] In the fragmented area of ​​coral reefs, even the surviving coral fragments are inevitably covered by gravel or covered by sand, and it is difficult to restore to their natural state only by their own grow...

AI Technical Summary

Problems solved by technology

The traditional fragmented coral reef restoration technology is to remove gravel and sediment and put artificial concrete reefs to stabilize the fragmented substrate and then transplant corals. However, this method is expensive, and the transportation and placement work consumes a lot of manpower and material resources. Fishing reef restoration methods make it difficult to recreate coral communities in situ on the seafloor
