摘　　要：结合区域地质与地球物理两方面的资料,运用盆地分析方法,研究表明南华北盆地中部凹陷自晚侏罗世以来,演化历经了走滑—拗陷—断陷—坳陷原型的序列叠加过程,与区域大地构造环境演变一致;并指出南华北盆地的演化主要受秦岭—大别造山带与郯庐断裂的双重控制。其自身结构特征及后期构造变化对油气成藏具有重要的勘探指导意义。Based on regional tectonic background and geophysical information, with basin analysis, it is believed that a series of prototype basin which have experienced strike-slip, depression, fault-down and again depression exist in the Tanzhuang-Shenqiu Sag after the Late Jurassic. And this basin mode evolution is consistent with geotectonic background. Structure and subsequent deformation are valuable for pool exploration. The orogenic zone of Qinling-Dabie and fault zone of Tanlu control the evolution of southern North China Basin.
