摘　　要：华南地区寒武系片Kunmingaspis—Chittidilla带出现了Redlichia、Bathynotus等重要下寒武统三叶虫,因此该带的归属出现了归中寒武统,归下寒武统及隶属中下寒武统过渡层的三种意见。本文提出了解决中、下寒武统界线划分的工作建议,主要是在过渡区选择剖面、详测剖面、运用多学科研究、整体修正有关三叶虫的时代。In the zone of Kunmingaspis - Chittidilla of Cambrian System in South China appeared some important trilobites of Lower Cambrian Series like Redlichia and Bathyno-tus, etc. Therefore three different opinions were given that the zone should belong to Middle Cambrian Series of Lower Cambrian Series or a transitional layer between Middle and Lower Cambrian Series. This paper has made several suggestions on the division of Middle and Lower Cambrian Senes. The writer suggests that the times of trilobites should be wholely revised by choosing sections in the transitional area and carefully surveying the sections, using multi-subject researches.
