摘　　要：研究层序地层学的重点在于层序划分,而层序划分的前提是识别和对比岩石记录中代表沉积趋势变化的地层界面。地层界面作为基准面与沉积速率相互作用产生不同沉积成因类型(强迫型海退、低水位和高水位正常海退以及海进)的响应,一部分可以提升至具有层序地层学意义的层序界面。目前,不同学者对层序界面的理解及使用存在着明显的差异和混乱,其导致的模式多样化也造成了解决实际问题时的混乱。The key research on sequence stratigraphy focused on sequence division, while sequence division should be based on the premise that the recognition and correlation of stratigraphic surfaces which represented changes in depositional trends in the rock record. Stratigraphic surface was the respond to the interplay of changes in rates of sedimentation and base level, as boundaries among different genetic types of deposit （forced regression, low stand and high stand normal regression, transgression ）, some of them could be the sequence surface of sequence stratigraphic significance. At present, many had their own understandings on sequence stratigraphy boundary and applied it in various ways. Therefore, a systematic organization on sequence stratigraphy was urgent.
