Abstract:

根据2006—2007年度4个季节航次的实测资料,分析了黄海冷水团水域浮游植物叶绿素及其粒级结构的时空分布特征及季节变化规律,结果表明,在研究海域30m以浅叶绿素总量的平均含量从高到低的顺序为:春季的(1.01mg/m3)、夏季的(0.81mg/m3)、秋季(0.72mg/m3)、冬季(0.68mg/m3);在叶绿素浓度大于1mg/m3和小于1mg/m3的区域浮游植物粒级结构差异较大,在整个研究海域,粒径较小的微型和微微型浮游植物对总生物量的贡献始终占主导(>65%),粒径较大的小型浮游植物在冬季和春季贡献率相对较高;从季节尺度看,浮游植物的平均粒级指数从大到小的顺序为:春季的(15.47μm),冬季的(11.08μm),秋季的(8.61μm),夏季的(6.52μm);尽管不同季节水文和化学环境差异显著,但是不同粒径浮游植物的贡献率随总生物量的变化表现出一致性的规律。对环境因子与叶绿素分布的相关分析表明,浮游植物的生长在夏季主要受到营养盐来源的限制,冬季主要受到水体混合引起的光照限制,秋季可能受到磷酸盐和水体混合的共同限制。浮游植物粒级结构的分布格局主要是由各组分在不同环境中的资源竞争优势决定的。
