地球深部物质组成、结构及其动力过程研究是当今固体地球科学中的前沿与生长点之一。在地质演化进程中，由于不同源（力源、热源等）的作用使得地球本体错综复杂。大尺度以及中小尺度上，地球内部结构的形态、性质、类型变化很大，地下介质物理与化学属性的不均一性、非线性以及各向异性广泛存在，诸如此类，使得地球深部研究呈为一庞大的复杂系统。本文从深部地球物理研究的反射、折射探测、层析成象以及有关复杂介质理论研究成果入手，简要地阐述地球深部研究中业已存在的多种复杂现象，并对这些复杂问题的解决提出了相应的建议。
Earth's deep composition, structure and dynamic process studies are among the frontiers and growth points in today's solid earth science. In the course of geological evolution, the nature of the earth makes the body of the earth complex due to the different sources (such as the source of force and heat, etc.). Large-scale and small-scale, the structure, property and type of the Earth's interior structure vary greatly. Inhomogeneity, nonlinearity and anisotropy of the physical and chemical properties of the underground medium are widespread, and so on, making the Earth's deep study a huge Complex system. This article starts with the reflection, refraction detection, tomographic imaging and the research results of complex media in deep geophysical research. It briefly introduces the complex phenomena that exist in the deep earth research and proposes the corresponding solutions to these complex problems Suggestions.
