东海、南黄海表层叶绿素a的粒级结构及其与环境因子的关系
he size composition of chlorophyll-a at surface layer in the East China Sea and Southern Yellow Sea and the relation with environmental factors
本文探讨了南黄海和东海海域表层叶绿素a的粒级结构特征，以及各粒级浮游植物叶绿素a含量与环境影响因子之间的相关关系。结果表明，整个调查海域范围内，各粒级浮游植物叶绿素a含量对总叶绿素a含量的贡献有显著差异，小型（microplankton，＞20µm）、微型（nanoplankton，3µm—20µm）和超微型（picoplankton，0.45µm—3µm）浮游植物的贡献率分别为30.3%、49.6%和20.1%。根据浮游植物总叶绿素a含量的不同，将37个站位分为三种类型：L型（0.7 mg/m3），M型（0.7 mg/m3—1.0 mg/m3）和H型（1.0 mg/m3）。这三种类型又根据小型（—m）、微型（—n）和超微型（—p）是否占优势进一步分成三类。在环境影响因子中，硅酸盐和小型、微型浮游植物生物量有较强的正相关性，和超微型浮游植物生物量有较强的负相关性，温度及盐度则和小型、微型浮游植物生物量有较强的负相关性，和超微型浮游植物生物量有较强的正相关性。
he characteristic of the size composition of chlorophyll-a at the surface layer in the East China Sea and Southern Yellow Sea was discussed as well as the relationships between the chlorophyll-a concentration of different size phytoplankton and the environmental factors. The results showed that microplankton (20µm), nanoplankton (3µm-20µm) and picoplankton (0.45µm-3µm) accounted on average for 30.3%, 49.6% and 20.1% of the total chlorophyll-a in the whole investigating sea area respectively. According to the total chlorophyll-a concentration, all 37 samples were classified into three types: Type L (0.7 mg/m3), Type M (0.7 mg/m3-1.0 mg/m3) and Type H (1.0 mg/m3). These types were further divided into three subtypes (-m, -n and -p), depending upon dominancy of micro (-m), nano (-n) and picoplankton (-p). Among the environmental factors, the positive correlation between silicate and the chlorophyll-a concentration of microplankton and
