| 内容記述 | To examine influences of tropical seagrass on marine physical environments, water flow and the sedimentation rate were measured in seagrass beds in the Andaman Sea, off Khao Bae Na, Trang Province, Thailand, in December 1998. Vertical profiles of water flow inside the seagrass beds and a sand bed were investigated using gypsum balls. Water flow inside beds of Enhalus acoroides (L.f.) Royle, which has large blades, was much smaller than that inside beds of Thalassia hemprichii (Ehrenb.) Aschers. and Halophila ovalis (R.Br.) Hook. f., which have small blades, or in the sand bed. The sedimentation rate measured with sediment traps inside the E. acoroides beds was greater than that inside the T. hemprichii beds at each station. The percentage of mud in the sediments inside an E. acoroides patch was higher than that outside it at the same station. Negatively proportional to water flow, the phi median diameters of sediments in the Enhalus beds were greater than those in the sand (unvegatated area) or Thalassia beds at the same station. These facts suggest that the vertical reduction in water flow depends on differences in the formation of seagrass meadows, and the sedimentation rate and sediment composition are influenced by the retardation of the water flow by the seagrass meadows. | |||||
