Abstract
The invention relates to an artificial algal reef for algae adhesion and seaweed transplantation. A reef body is a three-dimensional structure made of pervious concrete with a porosity of 15%-25%, six sides of the reef body are hollow, flow blocking plates are arranged on four sides of the reef body, a gentle water flow environment is created by an area encircled by the four flow blocking plates and is used for seaweed plant transplantation, the flow blocking plates and the reef body are integrally poured, bundling holes are arranged on two sides of the flow blocking plates and can be used for bundling scallop shell cages or oyster shell cages, algae adhesion effect is further improved, functions of the algal reef are expanded, and fixing strips are arranged at the bottoms of four corners of the reef body and are integrally poured with the reef body so as to guarantee stability after the reef body is placed into the sea. The artificial algal reef is low in cost, stable in structure and good in water permeability, the surface is rough to be favorable for algae adhesion, the gentle water flow environment created by the flow blocking plates is favorable for survival of transplanted seaweed plants, and after placed into the sea, the reef body is high in stability, multi-functional and expandable.
Description
Technical field
The present invention relates to a kind of artificial algal reef, is a kind ofly to take into account algae and adhere to artificial algal reef with sea grass transplanting specifically.
Background technology
Sea grass is the aquatic monocotyledon that is adapted to the marine environment life, has flourishing root system and subterranean stem.Sea grass bed is one of coastal waters three large Ecosystems, has important Ecology Action and economic worth.As most important primary producer on the earth, sea grass bed provides food and various habitat and spawning ground and protection field for numerous marine organisms.For the littoral ecosystem, sea grass bed catch sediments, stablize bed mud, the aspects such as windproof dyke strengthening, purifying water body, Cycle of nutrients, solid carbon (account for the annual solid carbon amount of whole marine ecosystems 15%) have vital effect, often are used as the biological indicator species of water quality and ecosystem health.
Due to the transition of natural conditions and the interference of mankind's activity, in world wide, nearly all sea grass bed all is among decline.In order to recover the sea grass resource, the various countries researcher has researched and developed many sea grass recovering method and technology, and wherein most widely used is the transplanting of sea grass plant.Yet, need the time of 1-2 month just can take root after the sea grass plant is transplanted, due to the effect of wave and morning and evening tides, just often not yet take root by wave after the sea grass plant is transplanted or morning and evening tides washes away, thereby after causing the sea grass plant to transplant, survival rate is not high, and the recovery effects of sea grass bed is not good enough.Therefore, in the sea grass transplanting marine site, how to build mild water environment, and then carry out the sea grass plant and transplant, thereby the survival rate of sea grass plant is transplanted in raising and the recovery effects of sea grass bed is sea grass plant implantation technique key issue in the urgent need to address.
The primary producer that algae is wanted as Marine Gravity And builds, provides for numerous biologies the aspect such as food to have important Ecology Action in purification of water quality, solid carbon, biological habitat.In order to recover the algae field, the means that usually adopt at present are to throw in artificial algal reef to the seabed.Artificial algal reef is the structure that artificially arranges in the waters; it provides the matrix of apposition growth for marine algae; make algae be able to Fast Growth; thereby attract the aquatic animal such as fish to come forage, breeding, g and D to the algae field, reach at last the purpose of optimization environments such as subsea, protection and propagation fishery resources.Yet the material of the present artificial algal reef that uses is stone or normal concrete normally, and cost is high, and the algae adhesion effect is not good enough, and is only to adhere to as purpose take algae, function singleness.Therefore, research and development new material, multi-functional artificial algal reef are very important.
Summary of the invention
Existing sea grass plant implantation technique transplanting sea grass plant survival rate is low and existing artificial algal reef cost is high in order to overcome, the algae adhesion effect is not good enough and the deficiency of function singleness, the invention provides and a kind ofly take into account algae and adhere to artificial algal reef with sea grass transplanting, this artificial algal reef not only cost is lower, being beneficial to algae adheres to, can also build mild water environment, thereby improve the survival rate of transplanting the sea grass plant.
The technical solution adopted for the present invention to solve the technical problems is: a kind ofly take into account algae and adhere to artificial algal reef with sea grass transplanting, it comprises reefs, it is characterized in that described reefs is the D structure thing of being made by pervious concrete; Six hollows of reefs, four sides arrange flow-stopping plate, four mild water environments of zone construction that flow-stopping plate surrounds, be used for the sea grass plant and transplant, described flow-stopping plate is to be made by pervious concrete, is cast for one with reefs, the flow-stopping plate both sides arrange the colligation hole, but colligation scallop shell cage or oyster shell cage further improve the algae adhesion effect, expansion algal reef function; The reefs tetrapod arranges fixed strip, and to guarantee the stability after reefs is thrown in the sea, described fixed strip is to be made by pervious concrete, is cast for one with reefs.
The invention has the beneficial effects as follows, the pervious concrete voidage is large, the artificial algal reef of constructing thus not only cost is low, Stability Analysis of Structures, and good water permeability, rough surface, be beneficial to algae and adhere to, the mild water environment that flow-stopping plate is built is beneficial to transplants the survival of sea grass plant, and after input enters the sea, reefs stability is high, diverse in function can be expanded.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is perspective view of the present invention.
1. reefs in figure, 2. flow-stopping plate, 3. colligation hole, 4. fixed strip.
Embodiment
In the drawings, constructed the reefs (1) of artificial algal reef by pervious concrete, six hollows of reefs, four sides arrange flow-stopping plate (2), be cast for one with reefs, flow-stopping plate (2) both sides arrange colligation hole (3), and the reefs tetrapod arranges fixed strip (4), is cast for one with reefs.
As embodiment, said structure is regular cube shape.Reefs is that the cast of 20% pervious concrete forms by voidage, six hollows, and the physical dimension of reefs length (not containing fixed strip) is 50cm, thickness 10cm; The material of the flow-stopping plate of four sides of reefs is also 20% pervious concrete for voidage, long 30cm, and high 20cm, thickness 10cm, lower edge is concordant with the reefs bottom surface, is cast for one; A colligation hole respectively is set in flow-stopping plate both sides, colligation hole centre distance reefs bottom surface 10cm, apart from reefs side outward flange 5cm, colligation bore dia 2cm, run through flow-stopping plate from a side of reefs, lead to another relative side, be used for colligation scallop shell cage or oyster shell cage (figure omits); At the reefs tetrapod, a fixed strip is set respectively, it is 20% pervious concrete that the fixed strip material is similarly voidage, and the physical dimension of length is 10cm, and entity is concordant with the reefs side, is cast for one.
On-the-spot sea area is laid and is hung take the group as unit, the every row individual distance of reef group 1～2m, and line space 3～5m, every row is thrown in 20～50 of artificial algal reef individualities, every group of 10～20 row.After the reef group forms, transplant the sea grass plant in the zone that four flow-stopping plates of each reefs surround, formation takes into account algae and adheres to artificial algal reef district with sea grass transplanting.
