Monitoring of marine environment was conducted in Weizhou Island,Guangxi in late September,2008 after an oil spilling event occurred,and community structure of phytoplankton was analyzed based on investigation data.The results showed that 106 species belonging to 44 genera were identified,including diatoms of 92 species in 35 genera,pyrrophyta of 12 species in 7 genera,cyanobacteria and chromophyta of 1 species in 1 genus each.The main dominant species included Chaetoceros curvisetus,Thalassionema nitzschioides and Chaetoceros lorenzianus.Distribution of phytoplankton was homogeneous.Average density of phytoplankton was 2 645.32×104cells×m-3 with a relatively higher cell density in the northwest,lower in the southwest around Weizhou Island.Abundance distribution of dominant species was generally similar with phytoplankton density.Shannon-Wiener(H') and Pielou(J') indices indicated that phytoplankton community was stable.In contrast to other relative researches,reports and data from State Oceanic Administration,our results suggest that in oil spilling ocean phytoplankton composition varied little,and phytoplankton density decreased less.Main dominant species were obviously subrogated and community structure was stable.Quick response to oil spilling emergency in marine ecosystem must be required.
