摘　　要：地层学是地质学重要的基础性学科,是地质工作的基础和支撑。近年来甘肃省地层古生物研究取得重大进展,积累了一批为全省地层研究修史立典的材料,及时总结这些成果素材,按照最新的理论、方法对区域地层进行划分、对比和精准化研究,是一个省区基础地质工作的重要内容。本文通过系统总结和梳理近年来甘肃地层学研究的最新成果,按照时间顺序和学科特点,系统性提出了按照多重地层划分对比理论和《中国地层指南及中国地层指南说明书》(2016年版)和《中国地层表》(2014)的框架和序列,全面提高甘肃地层研究精准度,为全省地质调查和相关研究提供基础支撑;对全省不同地区和不同地质单元地层界线层型和单位层型进行对比研究和厘定,建立新一代甘肃地层表的建议和路径。Stratigraphy is the base of geological work. In last several years, we have acquired a lot of achievements about the stratum and paleontology of Gansu province, which can provide historic material for related classic. Sequentially, using the newest theories and methods to summarize these achievements and make a division or comparison about territorial stratums in time, is the important content of our territorial work. In accordance with the theory of multiple stratum , Stratigraphic Guide of China (2016) and the China stratigraphic table (2014), this article intended to make a conclusion of these latest achievements and provide suggests about building a table about strata of Gansu province, which can improve the precision of strata and provide fundamental supports for geological investigations and related studies.
