【摘要】 随着地质、地球物理等资料的大量获得，＂弧后盆地扩张＂模式和＂地体拼贴＂模式也不能合理地解释东海盆地的演化，本文提出了东海盆地演化的一种新模式──＂持续拉张－脉动挤压＂模式，并探讨了该模式的力源机制，认为东海盆地演化的拉张力源是中国东部地幔软流圈自西向东（或东南）的蠕动流、岩石圈本身的陆壳（厚）到洋壳（薄）的扩张力、岩石圈的局部对流引起的侧向扩张及对岩石圈底部的热侵蚀；挤压力源则是菲律宾海大洋岩石田向西北运动的作用力。更多还原

【Abstract】 By analysinga great number of geologic and geophysical data of the East China SeaBasin,we begin to know that the "Back-Arc Basin Spreading"and the "Terrane Match-ing"patterns cannot explain the evolution of the East China Sea Basin reasonably anymore,Thus the authors put forward the"persistent Extension-pulsative Compression"pattern,discuss its mechanism of force sources,and think that the sources of extensionalforce are the mantle creep from west to east or to southeast in eastern China,the exten-sion of lithosphere from continental crust(thicker)to oceanic crust(thinner),and thelateral spreading and thermal erosion at lithospheric bottom bed caused by the local con-vection cell.The source of compressional force is derived from the movement fromsoutheast to northwest of Philippine Sea oceanic lithosphere.更多还原
