摘要
讨论了地史中主要生物类型出现、生物爆发和显生宙５次大的生物集群绝灭等生物圈演化事件与地球圈层演化的关系。这些生物圈事件包括生命起源与无核生物的发展、原核生物和真核生物的出现、后生动物的出现、带壳后生动物的出现、寒武纪早期的生物大爆发事件以及晚奥陶世、晚泥盆世、晚二叠世、晚三叠世和白垩纪末期的生物集群绝灭事件。在讨论显生宙５次大的生物集群绝灭的可能原因时，把地内原因与地外原因结合起来，阐述了地史中生物圈演化事件与地球圈层演化事件乃至地外事件之间的耦合效应。但是目前还难以识别事件形成的初因。
The correlation of the important organic occurrence or explosion and mass extinction events of biosphere with the evolutions of other earth spheres, such as the lithosphere, hydrosphere and atmosphere. It is indicated that the significant biosphere events, including the occurrence of procaryote, eucaryote, metazoan and shelly metazoans, Cambrian organic explosion and mass extinctions in the Late Ordovician, Late Devonian, Late Permian, Late Triassic and Late Cretaceous, were correlated with the evolutions of the other earth sphere, but the factors directly causing the biosphere events are still difficult to determine. It needs to improve the resolution of the stratigraphy study.
