摘　　要：评述了板块构造"登陆"以来的多岛洋构造、板内造山多岛海模式以及多岛弧盆系构造在造山带研究中的重要性。这3种模式在造山带的研究中均起到了重要的作用,深化了对造山带的认识。多岛弧盆系构造是认识造山带演化的切入点,能够全面解剖造山带的物质组成、结构构造和演化历史。基于多岛弧盆系的造山模式认为,弧后萎缩作用和弧前增生作用是造山过程的普遍现象,引起了弧-弧、弧-陆碰撞,这两种作用在造山带的形成演化过程起到了重要作用。多岛弧盆系的识别不但在造山带的研究中具有重要意义,而且对于分析前寒武纪大陆克拉通基底同样具有重要意义,前寒武纪克拉通的形成与弧前增生和弧后萎缩作用密不可分,多岛弧盆系构造的深入研究对前寒武纪大陆克拉通基底的研究具有重要启示。The paper presents a review of the value of archipelagic ocean model, archipelago model of intraplate orogenesis and composite arc-basin system tectonics since plate tectonic landing. All of these models contribute to the orogenic belt study, the knowledge of the orogenic belt. It is suggested that the composite arc-basin system tectonics should be the first step for the study of the orogenic belt evolution, for this can anatomize the orogenic material, texture, structure and evolution history. The backarc collapse and forearc accretion are common phenomena during orogenic process based on the composite arc-basin system model of orogenesis. The two processes result in arc-arc, arc-continent collsion and play an important part in the course of the formation and evolution of orogenic belt. The anatomization of composite arc-basin system not only plays an important role to study orogenic belt but also makes a difference for understanding Precambrian continental basement. It is believed that the formation of Precambrian continental basement is closely related to the processes of backarc collapse and forearc accretion. While the intensive research for the composite arc-basin system is important for inspiring the study of Precambrian continental basement.
