摘　　要：云南泥盆系地层完整 ,发育齐全 ,岩相多样 ,分布广泛 ;出露良好 ,接触界线清楚 ;生物群落丰富 ,化石保存完好。是中国南方陆相、海相泥盆系发育最好的地区之一 ,在国际上久负盛名。笔者对云南泥盆系的分区及地层划分进行了详细讨论。论证了泥盆系顶、底界线、内部界线和有关问题。总结出各组段的生物地层特征和沉积相特征 ,建立了各组段的生物组合带和生物带 ,探讨了云南泥盆系与国内外同期地层的对比问题。The Devonian strata in yunnan are developed completely, with various lithofacies, wide distribution, good outcropping, clear contact and plentiful fossils, which is one of the best development area of land and marine facies Devonian in South China and has been famous for a long time in the world. In this paper, the regional and stratigraphic division, the top, bottom and inner boundary lines of the Devonian in Yunnan are discussed in detail. The characteristics of biostratigraphy and sedimentary facies are summarized, the fossil and its assemblage zones of every Formation and Member are set up. And the correlation of Yunnan Devonian with those in China or abroad is discussed.
