摘　　要：在生物地层及年代地层研究的基础上,对本区上石炭统至中二叠统进行了层序地层学研究,从船山组至孤峰组下部共划分了5个三级层序、13个四级层序。通过五百多个米级旋回层序的研究,认为本区海盆有台地、台盆相间及盆地3个发展阶段,并得出4—6个米级旋回层序组成一个更高级别旋回的结论。Based on the biostratigraphic and chronostratigraphic data,the Carboniferous-Permian strata （from the Chuanshan Formation to the Gufeng Formation） in the Tonglu region of Zhejiang Province can be divided into five third-order sequences and 13 fourth-order sequences. In general, 4-6 meter-scale parasequences make a sequence of higher order. Sequence stratigraphic data also indicate that the 500-mthick Carboniferous-Permian succession in the Tonglu region represent a deepening upward sequence,beginning in platform facies and in deep water basinal facies.
