摘　　要：深时地球环境演变的定量化和系统化研究对于服务宜居地球建设意义重大。古土壤是认识深时地球历史演化的一把钥匙。文章简要地介绍了深时古土壤的鉴别特征,并从深时古气候环境重建、深时古景观恢复、深时关键带研究和重要地质气候事件响应等四个方面论述了深时古土壤的应用研究,旨在为深化深时古土壤研究和深入理解深时地球环境演变提供借鉴与证据。Quantitative and systematic research on the deep-time Earth environmental evolution is of great significance to serve livable Earth development in the future.Paleosol is a key to understand the evolution of the Earth’s environment in deep time.Diagnostic characteristics and features of deep-time paleosol-profile were summarized,and their applications in reconstructing the deep-time paleoclimate and paleo-landscape,rebuilding the deep-time Critical Zone and revealing the key geological-climate event in the ancient Earth were also discussed in this article.We aim at deepening the deep-time paleosols studies and providing the reference and evidence for understanding the deep-time Earth environmental evolution.

关 键 词：深时古土壤 深时古气候 古景观 深时关键带 地质气候事件
