摘　　要：海平面变化的主要表现形式是海侵和海退,它们是地球地质历史发展中最基本的现象和过程,也是层序地层学的主要构建机制,研究者以此建立层序地层格架及其模式,进行层序地层的成因单元配置和模式划分。随着研究的深入,已识别出两种海侵(正常海侵,快速海侵)和3种海退(高水位正常海退,低水位正常海退,强迫型海退),本文着重论述其在层序地层学中的定义及解释,并探讨其主要的沉积特点。Transgressions and regressions are main manifestations of the sea-level changes. As the most fundamental phenomena and processes in the earth history,they are the essential construction mechanism of the sequence stratigraphy,and favourable for the reconstruction of the sequence stratigraphic frameworks and models,and disposition of genetic stratigraphic units and classification of the models. Referenced from the previous results of research,the authors in this study have proposed two types of transgressions including normal transgression and rapid transgression, and three types of regressions including highstand normal regression, lowstand normal regression and forced regression. The present paper focuses on the identification and explanation of the abovementioned transgressions and regressions in sequence stratigraphy and their geological implications for the basin analysis and stratigraphic correlation.
