摘　　要：独山地区晚泥盆世弗拉期-法门期(F-F)和泥盆纪-石炭纪(D-C)的生物集群绝灭事件可能与海平面的快速大幅度下降有关,与藻类迅速而大量繁殖和生物生态链破坏的关系更为密切。The mass extinction and the recovery happened in the Frasnian - Famennian of the Devonian and in the Devonian- Carboniferous may relate to thesea- level descending rapidly ,and may closely relate to the algae growing largely up and the destruction of ecological chain. After F - F mass extinction, the trace makers,deposit- feeders may be firstly pioneer organisms and pathfinders in the ＂ecologically barren areas＂. They have played an important role in reforming the environments, and in rebuilding the ecological chain.
