The restoration of the ecosystem that coral is transplanted for coral reef has important function, so the coral being suitable for seabed drift sand environment transplants the important hope becoming and recover coral reef ecosystem.Now, the pattern mainly containing two kinds of human interventions of coral reef restoration of the ecosystem, one is by management means, protects eliminate with this pressure causing coral reef ecological disruption to coral reef region; Another kind is cultivated by field and transplant the methods such as coral to breed coral reef, to reach the object of recovery.Experiment shows, carrying out field cultivation and transplanting coral is the important manual intervention means that artificial coral reef recovers, China still belongs to the starting stage in this regard, transplant report about coral few, external as Japan, the U.S., Israel, Indonesia and Philippine transplant with the research of cultivating to coral and report more.

At present, for the transplanting of coral and the marine site that experimental research more options are transparent in water quality, stormy waves is less, sediment has reef more of cultivation, and the choosing, because the subsequent growth of reef base to the new coral transplanted plays conclusive effect of transplantation device or reef base.Because coral requires harsh to growing environment, the primary growth ability of project cost consulting item is comparatively fragile, and the marine environment rather harsh needing coral to transplant, as seabed drift sand environment, seawater is muddy, stormy waves is large, directly breed the subsequent growth easily affecting the new coral transplanted because of bad environments needing the sea area of restoration of the ecosystem to carry out coral, reduce coral and breed success rate, even cause sea area restoration of the ecosystem failure.And it is be directly fixed on seabed that currently used coral breeds reef Quito, effectively can not form steric environment at the reparation initial stage, thus affect the other biological of the ecosystem, as fish, shrimp and crab etc. perch, extend the repair time of the sea area ecosystem.

Utility model content

The purpose of this utility model provides a kind of portable coral reef base, adopt moveable structure, environment breeds initial stage impact on coral can be reduced, to coral breed and restoration of the ecosystem significant.

The technical scheme that the utility model adopts:

A kind of portable coral reef base, comprise pilum and basal disc, described pilum is designed to prismatic table shape structure, and the below of pilum bottom surface and surrounding thereof arrange support column, support hook, pilum can be made to be fixed on seabed after support column and support hook are inserted seabed completely, locking mechanism is set at the top of pilum; Described basal disc is designed to slice structure, basal disc is provided with fixing hole, utilize the locking mechanism on pilum that basal disc self-mountable & dismountuble is arranged on pilum top by fixing hole, at the upper bottom surface of basal disc and side uniform intervals, attachment circle is set, block or branched project cost consulting item (comprising part soft coral) can be fixed on attachment circle, make coral normal growth.

The pore size of described attachment circle is 3 ~ 5cm.

The spacing of the attachment circle on described basal disc, more than 10 centimetres, makes project cost consulting item have to be no less than the growth distance of 10 centimetres, is convenient to project cost consulting item normal growth.

The utility model structure is simple, adopt moveable structure, environment breeds initial stage impact on coral can be reduced, and utilizing pilum and basal disc to form steric environment can also be the other biological of the ecosystem, as fish, shrimp and crab etc. provide habitat, to coral breed and restoration of the ecosystem significant.
