摘　　要：湖平面变化分析是国内外地球科学研究的前沿之一,湖平面升降变化控制着层序地层界面的形成和不同类型沉积体的分布,对于沉积矿产资源的分布具有重要的意义。本文研究以辽中凹陷为研究区,东营组为主要研究层段,利用滨岸上超点方法反演东营期古湖平面升降历史。为陆相湖盆湖平面变化研究提供崭新的研究方法和思路;同时,由于本研究区为富油坳陷区,精确计算的湖平面变化史为隐蔽油气藏勘探提供分析依据。It is one research of earth science frontiers to analyze lake plane change. Lake plane elevation changing controls rorming sequence stratigraphy boundaries and distributing different kinds of sedimentary bodies, and it is very important to distribute sedi- mentary mineral resources. The paper researched Liaozhong depression and mainly studied Dongying formation, and utilized super-sho- reland method to inverse ancient lake plane history of Dongying formation. It provided a new mehod and thought for lake plane varation of continental facies and lake basins, therefore it had important scientific significance. At the same time, because the research area is fat oil depression, the accurate Lake plane variation history would provide analysis evidence for hidden oil vapour exploration with its important practical significance.
