南海大鹏湾浮游植物种群的季节演替

Seasonal Succession of Phytoplankton in Dapeng Bay,South China Sea

根据１９９０～１９９２年３年对大鹏湾进行的赤潮生态研究，分析了大自湾浮游植物的季节演替规律。春季甲藻的种类和效量均较多；而硅藻则全年均有分布，旦数量较高。对浮游植物优势种群的逐月变化作了研究。

The ecological studies on the Dapeng Bay,South China Sea,were carried out im 1990～1992.Seasonal Succession of phytoplankton populations was studied.Dinoflagellates,mainlyNoctiluca scintillans and Prorocentrum,Ceratium species,as,well as some Chrysophyta species,mainly Dictyocha fibuula,Distephanus,speculum etc. were dominant population in the spring.Diatoms,especially Skeletonema costatum and some Pseudonitzschia,Rhizosolenia and Chaetocerosspecies were dominant almost all over the year.The monthly variation of phytoplanktonpopulation was listed as well.
