通过分析华北地区晚石炭世的沉积环境及煤层分布特点，探讨了该区晚石炭世沉积相的典型类型，综合分析得出华北克拉通板块晚石炭世主要为陆表海环境，期间发生多次海侵海退事件，在郯庐断裂以东地区，主要发育有台地沉积体系、障壁-潟湖沉积体系及潮坪沉积体系；在盆地的北西缘地区发育潮坪泥炭沼泽，形成了海侵事件沉积，海退时期，中北部地区有利于发育潮坪泥炭沼泽和岛后泥炭沼泽，成为煤层的聚煤中心。

Through Late Carboniferous Epoch sedimentary environment and coal seam distribution characteristic analysis in the North China area, discussed typical types of sedimentary facies. From comprehensive analysis considered that on the North China Craton plate, during the Late carboniferous Epoch was mainly under epicontinental sea environment, multiple marine transgression and regres-sion events happened during this period. To the east of Tancheng-Lujiang fault zone, were mainly developed platform, barrier-lagoon and tidal flat sedimentary systems. At the northwestern margin of the area developed tidal flat peat bogs and formed transgression event sediments, during the regression, in central north part was favorable to develop tidal flat peat bogs and backbarrier peat bogs, proved to be coal accumulation center.
