The community structure of phytoplankton in Gouqi Island
摘要
Abstract
Depending on the bloom of Pseudo-nitzschia pungens in Gouqi Island in September,seven stations in four habitats around Gouqi Island were set up to analyze the community structure of phytoplankton.The abundance of phytoplankton in September is between 7.6 and 37.2（×106/m3）,Pseudo-nitzschia pungens dominated in the whole abundance which is 71.6 percent.Skeletonema costatum was one of the dominant species in the habitat of sandy beach compared with the small amount in other habitats.Combining with the environmental factors,the species-environment matrix was established to do canonical correspondence analysis.The results showed that angle,Chl-Flu,DO,salinity,P.quantum and temperature were the main factors affecting the structure of phytoplankton community（P0.01）.Skeletonema costatum was primarily influenced by temperature,so there was large abundance in the high temperature areas.According to the all-year data of species and environment,Pseudo-nitzschia pungens was primarily influenced by temperature.关键词
