摘　　要：胶莱盆地是中生代走滑拉分盆地,其形成与发育受到沂沭断裂和五莲-即墨-牟平断裂的控制。从晚侏罗世一晚白垩世经历了莱阳期、青山期和王氏期的盆地发展阶段。构造活动使不同时期的盆地格局发生改变,不同阶段盆地的次级构造单元也随之变化。不同阶段次级构造单元的形成与演变反映了构造活动对盆地发育的控制作用,表现在各单元之间沉积相发生突变。扬子板块与华北板块的碰撞,控制郯庐断裂带(沂沭断裂带)和五莲-即墨-牟平断裂的运动方向和强度,进而控制胶莱盆地的形成与发育。同时盆地发育也受到太平洋板块的影响与控制。Jiaolai Basin is a strike-slip and pull-apart basin controlled by the Yishu Fault Belt and Wulian -Jimo-Muping Fault. The Jiaolai Basin went through Laiyang,Qingshan and Wangshi stages in the Late Juras sic-Late Cretaceous. Fault activities reconstructed the structural framework of the basin in different stages, the substructural unites of the basin changed too. Form and evolution of the substructure unites in different stages show that tectonic movement controlled the basin development. The collision of the Yangtze Plate and the North China Plate controlled moving direction and strength of the Tanlu Fault Zone (Yishu Fault Belt). The Pacific Plate plunging into Europe-Asia Plate controlled the characteristics of the Yishu Fault and the formation and development of Jiaolai Basin.
