藻类在线分析仪在海洋环境监测中的应用研究

摘要

利用藻类在线分析仪测定了3种不同微藻（盐藻、角毛藻、金藻）的荧光值，同时采用经典方法同步测定叶绿素a浓度和细胞密度。分析结果显示，荧光值与叶绿素a浓度、细胞密度具有显著的正相关关系。因此，利用藻类在线分析仪能够反映海水中微生物量的变化，也能够反映海水中叶绿素a浓度的变化。藻类在线分析仪的应用，能够及时掌握海水中生态环境的变化，为海域自然灾害的预警提供有力的科学依据。%T he fluorescent value of three microalgaes including Dunaliella salina ,Chaetoceros ,Chryso-phyta were deter mined by algae online analyser .Compared with cell density and chlorophyll -a con-tent ,it showed good linear interrelation .So ,algae online analyser can reflect the variety of microalgal biomass and chlorophyll -a content from sea water .The application of algae online analyzer can know ecology enviro nment change ,which supply scientific evidence for natural disaster area warning .
