摘　　要：盆地系统和造山带系统是大陆岩石圈上的两个主要构造单元，其包括地质历史中曾存在的和消失的盆地、大洋、大陆边缘及陆地。因此，盆山转换研究、探索盆转山和山控盆的过程则成为大陆地质的前沿研究领域。沉积地质学通过盆山转换和转换过程的分析研究，并以大陆边缘为主，对盆地分析、露头层序地层学研究，在盆地沉积相的时空配置和演化、大陆边缘转为前陆盆地过程中，分析海－陆环境在时空上的四个转换过程和自演化序列。盆山转换的另一关键是层序等时格架的建立。层序的等时性应包括层序界面（单一的和复合的界面）、层序和时间损失量。The basin system and orogenic system are believed to be two essential tectonic units within the continental lithosphere,including pre existing but now extinct basins,oceans and landmasses in geologic record.The researches on the basin range transition thus become the frontiers of continental geology.In this paper,thd spatio temporal evolutionary processes and self evolutional sequences in oceanic and continental environments are probed on the basis of basin analysis and outcrop sequence stratigraphy.Another key problem in the studies of the basin range transition is the construction of the isochronous stratigraphic framework.The isochronism of sequences should encompass sequence boundaries(simple or compound)sequences and time losses.
