摘　　要：大陆内部壳、幔结构和动力学机制远比大洋"刚性"板块复杂得多,故板块"登陆"必受限定。为此必须重新认识大陆内部物质在力系作用下的重新分异、调整,即必须重新厘定其大陆内部形成的深层过程和动力学机理。文中指出了以壳、幔结构与深层过程为支柱的地球动力学应予以研究和探索的十大基本科学问题。它们的"核心"主题乃是研究、探索深部物质与能量的交换、运动行为与轨迹和动力学响应。The structure of the crust and the mantle and the dynamic mechanics of intra-continent are more complicated than those of the ＇rigid＇ oceanic plate, and hence the plate tectonics of the continent should be redefined i.e., it is necessary to recognize the differentiation, modulation and motion of the material inside the continent under the force system and reestablish the deep process and mechanism of continental formation. This paper presents ten basic problems of the geodynamics based on the structure of the crust and the mantle. The key subjects of these problems include the exchange of deep process and material, the movement and behavior and the dynamic response.
