以６０个大体均匀分布于华北地台的地层剖面为基础，以晚古生代聚煤盆地的整体性为依托，对华北晚古生代地层进行了多重划分研究。在岩石地层方面，研究了地层分区，划分了１８个岩石地层单位“组”。分析了组的穿时性；在生物地层方面，重点介绍了、古植物和孢粉虫物地层，划分了各个组合带、延限带和顶峰带，分析了生物演化系列，空间展布和对比，提出了多方面的新认识；在年代地层方面，应用界线层型概念以及与首要门类生物地层单位界线的相关性。讨论了各个年代地层界线，包括石炭系、三叠系界线，石炭系内部界线和二叠系内部界线．并和国际通用阶名进行比较，建立了系统的和完整的华北晚古生代年代地层序列。
Based on the stratigraphic profiles of 60 geographically distributed in the North China platform, based on the integrity of the Late Paleozoic coal basin, the study was conducted on the multi-division of the Late Paleozoic strata in North China. In terms of lithostratigraphy, stratigraphic zoning has been studied and 18 “strata” of lithostratigraphic units have been divided. In the aspect of biostratigraphy, we mainly introduce the ancient plants and the layers of pollen worms, and divide the various combination zones, delineation zones and peak zones, and analyze the series, spatial distribution and contrast of the biological evolution , Put forward a new understanding of many aspects; in the age stratigraphy, the application of stratification concept and the relationship between stratigraphy and primary stratigraphic units. The stratigraphic boundaries of various ages are discussed, including the Carboniferous, Triassic, Carboniferous and Permian boundaries. And compared with the international common name, established a systematic and complete sequence of the Late Paleozoic strata in North China.
