在全面了解陆相层序地层学研究现状的基础上，认为陆相层序及体系域发育仍受湖平面相对变化控制，构造、气候及沉积物供给的控制作用最终通过湖平面变化表现出来。而湖平面的变化可分为完整旋回与不完整旋回两种情况，进而提出了所形成的层序及体系域模式：在完整旋回中形成了湖泊充填、湖泊扩张、湖泛和湖泊萎缩４个体系域，对应层序为Ⅰ型层序；在不完整旋回中形成了湖泊充填、湖泊扩张、湖泛３个体系域，或者湖泊扩张、湖泛、湖泊萎缩３个体系域，对应层序为Ⅱ型层序。以松辽盆地西部斜坡实际工作为例，提出了中生代层序及体系域划分方案。
On the basis of comprehensive understanding of the research status of terrestrial sequence stratigraphy, it is considered that the control of terrestrial sequence and system development is still controlled by the relative change of lake level, and the structure, climate and sediment supply finally show through the change of lake level. The change of the lake plane can be divided into two types: complete cycle and incomplete cycle, and then the sequence and system domain model are proposed: four stages of lake filling, lake expansion, lake pan and lake shrinking are formed in the complete cycle In the incomplete cycle, three systems of lacustrine filling, lacustrine expansion, lacustrine system, or lacustrine expansion, lake flooding and lake shrinkage were formed, and the corresponding sequence was Ⅱ type sequence. Taking the actual work of western slope in Songliao basin as an example, the paper presents the plan of Mesozoic sequence and system domain division.
