摘　　要：在收集大量前人研究成果的基础上，对华北地台东部及邻区（ 郯庐断裂带以西，燕山及其以南，太行山及其以东，秦岭—大别造山带以北） 的早、中侏罗世盆地和晚侏罗世—早白垩世盆地进行原型恢复，编制了该地区中生代原型盆地分布图。结合区域构造动力学背景进行了原型盆地分类：早、中侏罗世盆地为压性盆地，分为大中型坳陷盆地和小型坳陷盆地；晚侏罗世—早白垩世盆地成盆模式有３ 种（ 走滑盆地，伸展盆地，类前陆盆地） ，将该地区分为西部伸展盆地区、东部走滑盆区地和南部挤压盆地区。认为该地区中生代盆地分布及演化受控于滨太平洋区域构造带和秦岭—祁连区域构造带的作用，由于盆地规模比较小，热坳陷也比较小，使这些中生代盆地的含油气性与同一地质时代发育的松辽盆地迥然不同。Based on a collection of large amount of results of previous researchers, prototypes of Early Middle Jurassic basins as well as Late Jurassic Early Cretaceous basins in East Huabei platform and its neighboring region (west of Tanlu fault belt, Yanshan mountain and its south, Taihangshan mountain and its east, and north of Qinling Dabieshan orogenic belt) are restored, and a distribution map of prototypes of Mesozoic basins is constructed. Combined with the background of regional structural dynamics, prototypes of basins are classified: Early Middle Jurassic basins are compressive ones which can be further classified into large, medium and small depression basins. There are 3 type of basin formation model (strike slip basins, stretch basins and foreland like basins) for Late Jurassic and Early Cretaceous basins which can be further classified into western stretch basin region, eastern strike slip basin region and southern compressive basin region. It is recognized that the distribution and evolution of Mesozoic basins in this region was controlled by Pacific tectonic zone and Qinling Qilian regional structural zone. Because these basins are relative small in size and their thermal depressions are relatively small also, the oil and gas bearing property of these Mesozoic basins will be quite different from that of Songliao basin developed in the same geological age.
