浮游植物生物量研究Ⅱ.胶州湾网采浮游植物细胞体积转换生物量

Study on phytoplankton biomass Net-phytoplankton measurement biomass estimated from the cell volume in the Jiaozhou Bay

基于浮游植物细胞体积转换法获得的胶州湾浮游植物细胞生物量，计算了胶州湾水体中同采浮游植物生物量，并与浮游植物细胞计数结果进行了周年变化的比较和优势种分析．研究结果表明，调查期内，浮游植物细胞数量出现两次高峰（主峰１月份，次峰９月份），转换生物量仅出现一次高峰（８月份）；优势种分析表明，上述峰值期的不同，与浮游植物群落结构及不同种群细胞的个体大小密切相关．浮游植物细胞体积转换生物量不仅能较客观地反映浮游植物现存量，又能从群落、种群结构角度解释能量分布及不同种群对浮游植物生物量的各自贡献．

Based on phytoplankton cell measurement biomass from the cell volume, the net-phytoplankton measurement biomass in the Jiaozhou Bay is calculated, and the anniversary variety is compared with the cell counting result, the dominant spedes in the Jiaozhou Bay are analysed. It shows that, during the investigation, there are two cell concentration peaks (the main peak is in January 1996 and the vice Peak is in September 1995), but the Peak of the measurement from the cell volume appeared only once (in AugUSt 1995); the dominant species analysis shows that the above-mentioned difference is from the difference Of the phytoplankton community and phytoplankton cell volume during the investigation. The phytoplankton measurement biomass estimated from the cell volume method is not only more precisely estimating the standing stock but also represents the energy now at the phytoplankton community and population level.
