The necessary means of building the algae field is exactly to throw in artificial algal reef to the seabed.Artificial algal reef is the structure that artificially is provided with in the waters; it provides the matrix of apposition growth for marine algae; make algae be able to quick growth; thereby aquatic animals such as attraction fish come forage, breeding, g and D to the algae field, reach the purpose of optimizing environments such as subsea, protection and propagation fishery resources at last.
Algal reef is thrown in after the sea, can slowly grow various algae on the reefs, but because multiple benthon sea urchin ingesting particularly to algae, cause the algal grown on the reefs to be subjected to very big influence, thereby influence the construct effects of biology of artificial algae field, serious meeting makes the dead disappearance of the algae on the reefs, artificial algae field construction failure, thus do not reach the purpose of repairing water environment, transforming the habitat, seabed.To this problem, also there is not very effective solution at present, Japan once used etting to cover on algae portion outside the venue, climb up the reefs algae that ingests to prevent sea urchin, though obtain certain effect, but engineering is bigger, and labor intensive, material resources and financial resources prevent that biologies such as sea urchin, shellfish from becoming the major issue that artificial algae field is built success or failure to ingesting of algae so how to design reefs construction artificial algae field.
Summary of the invention
The invention provides a kind of artificial algal reef of anti-sea urchin food evil, this artificial algal reef can prevent effectively that sea urchin is to the ingesting of algae on the reefs, to solve the problem that prior art exists.
In order to reach the purpose that solves the problems of the technologies described above, technical scheme of the present invention is, a kind of artificial algal reef of anti-sea urchin food evil, and it comprises reefs, it is characterized in that described reefs is the D structure thing of being made by several reef dish stacks, the section shape at reef dish periphery position is a zigzag.
In the present invention, also have following technical characterictic: the reefs top is made into rough surface.
In the present invention, also have following technical characterictic: described reef dish comprises top reef dish, middle reef dish and bottom reef dish, and top reef disk shape is a dish, and bottom reef disk shape is the dish of back-off, and middle reef disk shape is the back-off dish and is just putting the dish composition.
In the present invention, also have following technical characterictic: reefs is that armored concrete is made, and reef dish upper surface sprinkles the cullet slag at the top, and making itself and concrete fixed is one, and the cullet slag accounts for 10～45% of top reef dish cart area.
In the present invention, also have following technical characterictic: the fleam α angular range of reef dish periphery edge is 5 °～60 °.
In the present invention, also have following technical characterictic: described reef dish is circle or rectangle.
Design of the present invention is that reef dish vertical plane is made the likeness in form zigzag, and several reef dishes are layering and form artificial algal reef integral body.Because reef dish side side face forms sawtooth like shape; also can be described as a jiao in the triangle; thereby sea urchin is difficult to get over serrated face; can't arrive the artificial algal reef top; thereby protected the growth of marine alga; make algae be able to quick growth, reach the purpose of optimizing environments such as subsea, protection and propagation fishery resources.
The invention has the beneficial effects as follows through flume experiment, prevent that the sea urchin effect of ingesting is remarkable, and Stability Analysis of Structures, make simple, cost is low, and simultaneously rough surface helps marine alga adhering on reefs, and adds the faint sunlight that the cullet slag can reflection and transmission be gone into the seabed, make the root of algae obtain more illumination, help algae grows.
