东南亚地处重要的区域地球动力学交汇带，三面被向内俯冲的体系环绕，构成了地球上规模最大且最为复杂的汇聚型俯冲体系。俯冲物质的深部循环及最终归宿一直是个难以捉摸的科学谜团，既缺乏系统的科学观测，也没有公认的理论模型。在这篇综述中，我们介绍了过去几十年间关于东南亚弧形俯冲体系（CSS）的地震层析成像深部结构、物质交换及演化历史的地球物理、地球化学和地球动力学模型，并指出在构建地幔深部结构以及量化俯冲板块与内部再循环物质之间的反馈（这与质量和能量转移这一主题下的动力学过程相关）方面仍面临的挑战。我们认为，加深对CSS内部地震层析成像的理解，结合地球化学分析和计算地球动力学建模，将有助于更清晰地描绘控制地球上此类环形俯冲体系演化的动力学机制。
Southeast Asia is located in an important regional geodynamic intersection zone surrounded by inward subduction systems on three sides, consisting the largest and most complicated convergent subduction system in the earth. The deep circulation and ultimate destination of the subducted material have always been an elusive scientific mystery, lacking both systematic scientific observation and accepted theoretical models. In this review we present geophysical, geochemical and geodynamical models in last decades regarding the seismic tomographic deep structure, material exchanges and evolution history of the Curved Subduction System (CSS) in SE Asia, and identify remained challenges in constructing the deep mantle structure and quantifying the feedback between the subducting slab and the interior recycling materials relevant to the dynamic processes within the theme of mass and energy transfer. We propose that increased understanding of seismic tomography within the CSS, combined with geochemical analysis and computational geodynamic modeling, will aid clearer portrayal of the dynamic mechanisms controlling the evolution of such ring-shape subduction systems on Earth.
