摘　　要：中国大陆及邻近陆域海域是晚古生代以来由多个较小的板块或地块汇聚形成的。中生代亚洲东部岩石圈拉张解体和减薄。古新世印度与欧亚大陆碰撞引起地壳缩短隆升,形成青藏高原和喜马拉雅造山带。根据中国大陆及相邻区域天然地震、人工地震及其他地学资料,采用多学科多手段进行反演。对沉积层、地壳、岩石圈特性及厚度变化进行研究,探讨中国大陆及相邻陆域海域岩石圈结构特征及深部动力学问题。The continent of China and its adjacent land and sea areas were formed by convergence of a number of small plates and blocks since the Late Paleozoic. In the Mesozoic, in eastern Asia the lithosphere underwent extension, breakup and thinning and the asthenosphere upwelled, forming a giant rift system; whereas in western Asia India-Eurasia collision in the Paleocene resulted in crustal shortening and uplift, forming the Qinghai-Tibet Plateau and Himalaya orogenic belt. Data of seismic and explosion seismic surveys and other geoscience data obtained from continental China and its adjacent areas have been inverted by multidisciplinary means. The changes in characteristics and thickness of the lithosphere, crust and sediment layers have been studied and a series of maps compiled to discuss the characteristics and geodynamics of the lithosphere beneath continental China and its land and sea areas.
