地球深部研究的复杂性及其对策

THE COMPLEXITY IN THE STUDY OF EARTH DEPTH AND ITS COUNTERMEASURE

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。

The study of material constitution,structure and dynamic process in earth's depth is one of the major focuses in Geosciences. In the process of Geological evolution, Different sources(force source,heat source etc.) make the sophicated earth inner formed. Whether on Large or middle,and small scale, the pattern, property and type of the structure in the inner of the earth are different obviously from one place to another.The inhomogenity of physical and chemical property,nonlinearity and anisotropy exist everywhere, Which make the study of earth depth be a huge complicated system. Considering the achivements of reflection,refraction survey,tomography and classic studyfor complicated media,several kinds of complicated phenomenon existed in the study of earth depth are simply explained,and some suggestion for the solution of these complicated problems are maken.
