Coral reef transplanting repairing device applicable to South China Sea

Abstract

The invention provides a coral reef transplanting repairing device applicable to South China Sea. The coral reef transplanting repairing device comprises a lateral wall, bottom feet, a rigid support, a base plate, a control box, a cross rotary knob, a worm, a bevel gear and a coral cultivation device. By the arrangement, the coral reef transplanting repairing device has the advantages that during a coral spawning period, the coral reef transplanting repairing device fixed on the outer slope in front of a coral reef attracts and fixes drifting coral larvae, and a hole is drilled in the degenerated coral reef and the coral cultivation device attached with coral is inserted and fixed into the hole after the coral is mature so as to complete the ecologic repairing of the coral reef. By the coral reef transplanting repairing device, the problems that a traditional coral reef transplanting repairing device is low in coral transplanting survival rate and difficult in underwater coral transplanting and fixing, the coral larvae are preyed easily and covered by sediments, and the like are solved, and coral reef transplanting repairing efficiency and quality are increased.

Description

Technical field [0001] The invention relates to coral reef ecological restoration, in particular to a coral reef transplantation restoration device suitable for the South China Sea. Background technique [0002] Coral reefs are formed naturally by the remains of shallow reef-building corals and other attached reef organisms through various accumulations. They belong to marine sedimentary rocks and are one of the marine ecosystems with extremely high biological productivity and biodiversity. my country is rich in coral reef resources. The area of ​​coral reef represented by coral reefs in the South China Sea is about 37,200 km. 2 , Accounting for 5% of the world’s coral reef area, ranking second in Southeast Asia, and occupying an important position in the global marine ecosystem. [0003] The coral reefs of the South China Sea islands mainly include atolls, platform reefs, underwater reefs and underwater reef beaches, as well as scattered tower reefs (Martian reefs, etc.), in addit...

AI Technical Summary

Problems solved by technology

At present, the restoration of coral reefs in the South China Sea mainly faces the following problems: (1) The survival rate of coral transplantation is low; (2) The transplanted corals are difficult to fix; Effects of Biological Competition
