摘要
本文从现代理论地层学的概念出发，对华北二叠纪地层划分对比中的几个重要问题，进行了探讨：①岩石地层、生物地层与年代地层的含义；②岩石地层基本单元一组的划分；③岩石地层对比与年代地层对比；④重要标志层在区域对比中的作用；⑤华北二叠系上、下统分界线的划分。通过对这些问题的探讨，暴露了在地层划分对比中，因长期受传统地层学与统一地层划分某些观点的影响所产生的问题，今后应该注意什么和如何处理。
According to the basit conception of modern theoretical stratigraphy,some majot issues indivision and corelation of permian strata in North China are discussed in the pcper.1. Implications of the terms of lithostratigraphy,biostratigraphy and chronostratigraphy.2. Division of the basic lithostratigraphic unitformation。3. Lithostratigraphic correlation and chronostratigraphic correlation.4. The role of major marker beds in regional correlation.5.Delimitation of boundary between the Upper and Lower series of Permian system in NorthChina. From the above mentioned discussion,some problems on stratigraphic division andcorrelation made by some of our geological exploration departments,as a result of a long terminfluence of some standpoint of traditional stratigraphy and unification attempt of variousstratigraphic divisions are revealed. The author points out what we should pay attention to andhow we should do.
