摘　　要：寒武纪是生命演化史上的重要时期,各门类后生动物爆发式出现,标志着地球生命系统发生了革命性转变。作为显生宙的第一个纪,寒武纪自1835年建立以来,经过180多年的研究,其年代地层框架已基本确立。中国的寒武系研究也有一百多年的历史,地层分区及年代地层几经革新。近年来,中国寒武系综合地层学研究取得了一系列新进展,在岩石地层划分对比方面也形成了若干新认识。本文基于对已有地层资料和新进展的分析整理,以组为基本单元,以生物地层和化学地层为依据,以对比表的形式总结和梳理了中国寒武系8个地层区129条代表性剖面的岩石地层划分和对比,提出了一些新的划分与对比方案和建议。Cambrian is the most significant interval in the history of life. The explosive occurrences of nearly all metazoan phyla during the early Cambrian mark a revolutionary transition of the Earth-life system. As the first period of the Phanerozoic time, the Cambrian chronostratigraphic framework has been basically established through extensive efforts of more than 180 years since it being named in 1835. The study on Cambrian stratigraphy in China has a history of more than 100 years, and its subdivision and chronostratigraphic framework were reformed several times. During recent years, a series of innovative progresses were made on integrative stratigraphy of the Cambrian in China, and many new understandings and recognitions were reached in subdivision and correlation of Cambrian lithostratigraphy. Based on analysis and reorganization of existing stratigraphic data and the latest progresses, this paper summarizes and sorts out a Cambrian lithostratigraphic framework of subdivision and correlation for 129 representative sections in 8 stratigraphic regions of China with lithostratigraphic formation as basic unit through biostratigraphic and chemostratigraphic means. Some new schemes are proposed concerning the lithostratigraphic subdivision and correlation.
