Big typical case's marine ecosystems, the sea grass bed being made up of sea grass is the ecosystem-type that productivity is the highest, has important life
State service function and economic worth, and far above mangrove and coral reef.
Sea grass is the food source that marine animal depends on for existence, and such as cowfish, sea urchin, conch, green turtle etc., the most directly food grass is
Raw, other marine animal is then to sustain life by eating these " food grass " animals, is the most also that juvenile prawn, postlarva provide hidden
Cover and good protection place, look for food place and habitat；Due to the sea grass well developed root system of sea grass bed, beneficially storm resisting pair
Marine benthos are had protective effect by the erosion of offshore substrate.In ocean, sea grass bed can absorb the titanium dioxide in water
Carbon, has huge carbon reserve capabillity, compares the uptake of the annual 30000 tons of carbon dioxide of the every sq-km of land forest, often puts down
Side's km sea grass bed can absorb 8.3 ten thousand tons of carbon dioxide, every year it is of particular importance that be different from forest by carbon dioxide with biology
Wooden state is fixed, and sea grass is to be stored in soil by carbon dioxide, and the carbon sequestration time was more than more than thousand；Meanwhile, sea grass passes through
Photosynthesis, releasing oxygen is dissolved in water body, and dissolved oxygen is played supplementary function, is effectively improved fisheries environment；Sea grass is to from land
