摘　　要：植物活动痕迹与作为生态系统痕迹化石的古土壤（Ｐａｌｅｏｓｏｌ）关系密切［１］，两者都是现代痕迹学研究的重要内容．根据东濮凹陷油气区钻井岩芯中获得的资料，对植物根迹和古土壤作了环境分析，指出其在辨别海相、非海相、层序界面［２］、古地理、古气候方面的显著作用。Roots and paleosols can be regarded as trace fossil of plant as well as a trace fossil of an ecosystem respectively. Both of them are closely interactive and are currently the main subject in the study of modern Ichnology. Materials of fossil plant trace and fossil soils collected from Shahejie formation, Dorgpu depression are analysed in terms of reservoir sedimentology. The results show that plant trace fossils and paleosol can be a powerful tool in recognition of marine or non_marine sediments and sequence boundary in particalar and may contribuate a lot in analysis of palaeograply and palaeoclimatology in general.
