Description
Technical Field
The application belongs to the technical field of ecological restoration of coral reefs, and particularly relates to a device for reducing sea water turbidity in a coral reef sea area.
Background
The coral reef is mainly formed by piling calcareous remains of hermatypic corals for a long time, and is widely distributed in subtropical sea areas of tropical and heating places, and the total distribution area of the coral reef reaches 2700 ten thousand square kilometers. The tropical sea area of China is wide, the coral reef is widely distributed, and the reef-building coral is various. The coral reefs are rich in south China sea islands, penghu islands, guangdong, guangxi places and the like. A typical coral reef topography consists of a relatively horizontal reef surface that connects to the deep sea seabed and is steep, extending to the shore beach, where there is often a raised reef crown at the interface of the reef surface and the reef surface.
Coral consists of coral population and calcareous exoskeleton secreted by the coral population, yellow algae are present in healthy coral endothelial cells, the yellow algae and the coral are symbiotic, and provide nutrition for the coral by photosynthesis, so that the coral can continuously secrete the calcareous exoskeleton to enable the coral reef to develop.
Corals are a mixed nutrient organism and underwater light availability is a prerequisite for corals to photosynthesis, so they still require a fraction of the light to sustain growth.
Research shows that underwater light availability is greatly affected by water turbidity. The underwater light availability can be determined by changing the scattering and absorption characteristics of the water body to light when the turbidity changes. For example, hyperspectral data under dredging plumes show a decrease in blue and red wavelengths and a clear shift to yellow-green. This region lies outside the main absorption peak of the photopigment, which means that corals absorb poorly in this part of the spectrum and drive photosynthesis with relatively low efficiency. Thus, an increase in turbidity will reduce the availability of light under water, which in turn reduces the distribution and abundance of corals.
Currently, most coral reefs in the world are currently experiencing chronic or acute turbidity-increasing events, the production of which is often associated with coral reef dredging activities, sediment re-suspension, surface runoff, and the like.
In view of the adverse effect of weak light conditions caused by the increase of turbidity in the coral reef sea area on the coral reef growth, and the turbidity increase in recent years plays a leading role in reducing the underwater light availability of the coral reef, and the traditional turbidity removing device generally adopts the combination of sedimentation, aeration and membrane treatment technologies, the equipment is complex, the maneuverability is poor, the energy consumption is high and the cost is high, so that the artificial intervention is needed to reduce the turbidity of the water body in the coral reef sea area by an innovative method to increase the underwater light availability, thereby promoting the coral growth and accelerating the development of the coral reef.
