第四纪岩层作为与人类活动最密切相关的地层,在研究物种进化及人类活动中占据了重要的地位。本文以第四纪生物与人类活动为例探讨研究第四纪岩层的重要意义,同时指明了研究第四纪岩层对人类工程建设及灾害预防的重要性。 Quaternary strata, as the strata most closely related to human activities, occupy an important position in the study of species evolution and human activities. In this paper, Quaternary biology and human activities as an example to explore the significance of Quaternary strata, at the same time indicate the study Quaternary rock formation of human engineering and disaster prevention importance.
