摘　　要：运用高分辨率层序地层学的观点和分析技术 ,建立了时间 -层序地层格架 ;以基准面旋回为基础 ,论述了河北石炭 -二叠纪层序发育特征 ,地层分布模式和盆地充填演化序列以及基准面变化与陆表海盆地煤聚集的成因联系 .结果表明 :河北石炭 -二叠纪含煤岩系为内陆表海盆地沉积 ,盆地的生成演化及其沉积作用与基准面变化密切相关 ,聚煤作用的发育也受到基准面变化的严格控制 ,形成旋回结构十分清晰的含煤层序 .The framework of time sequence stratigraphy was established according to the point of view of high resolution sequence stratigraphy. The development characteristic of the sequence, the distribution pattern of strata, the basin evolution and filling , and the relationship between variations of base level and coal accumulation of epicontinental basin were expounded based on the base level cycles. The result shows that the C P coal measures in Hebei is a series of basin deposit of inner epicontinental sea. The formation and evolution and sedimentation of the basin is intimately related to the changes of the basin base level, which controls the development of the coal accumulation, forming a clear coal bearing sequence in the cycle.
