摘要: 在层序地层研究成果基础上，以沉积体系域和相关界面为编图单元，采用体系域压缩法和瞬时编图法，编制了西南地区二叠纪层序古地理图，全面系统地阐述了该区二叠纪层序古地理演化特征。与传统的岩相古地理图相比，层序古地理图具有动态、精确、等时和实用等优点。
Abstract: On the basis of a study of sequence stratigraphy, with the systems tract and related boundaries as the mapping unit and using the systems tract condensation method and instantaneous map production method, the authors have compiled the Permian sequence paleogeographic map of southwestern China and systematically elucide the characteristics of the Permian sequence paleogeographic evolution of the region. Compared with the conventional lithofacies paleogeographic map, the sequence paleogeographic map has the advantages of dynamic state, accuracy, isochroneity and practicality.
