摘　　要：在生物地层和岩石地层研究的基础上，通过露头层序地层分析和测井资料层序地层分析，应用米兰柯维奇旋回的原理，对测井曲线进行快速富里埃变换成高分辨频谱曲线的计算机处理，对黔南地区中泥盆地层进行详细研究，识别出４个层序和２１个高分辨率层序，并计算出它们的沉积速率和持续时间。Sedimentary environments of southern Guizhou were alternative carbonate and clastic rocks in middle devonian. Based on the analysis of sequence stratigraphy in outerops and well logs, the authors recognized 4 sequence and 21 high resolution sequence stratigraphy of middle devonian in southern Guizhou. Sedimenting time of middle devonian has been calculated is 14.5 Ma. Applying sequence stratigraphy methods, the author has distinguished 4 T-R cycles in middle devonian in southern Guizhou. Compared with sea level changing patterns in north america platform and european mainland at the same period, the 4 T-R cycles of middle devonian in southern Guizhou are global.
