摘要：

苏北如东地区泰州组中,产有较多类型的沼、水生植物孢粉、藻类,均与漫流、静水的湖泊、沼泽有关．通过与现代湖泊生物带模式的对比,泰州组经历了藻类带萌芽阶段,挺水植物带、浮水植物带形成阶段,沉水植物带和水底无植物带发展阶段,及浮游植物带衰退阶段、轮藻植物带消亡阶段的完整水盆演变过程.

Abstract:

Abundant sporo-pollen of hydrophyte and helophyte as well as algaes found in theTaizhou Formation are related to slow flow and stillwater lakes or marshland environment. As compared with the biozone model of present-day lake, the formation underwentthe complete process of water-basin evolution stages: algae germination stage, emergedplant stage, floating plant stage,immersed plant stage and benthophyte-lacking stage,plankton degeneration stage.Charaphyta extinction stage.
