Review of the gravity density interface inversion

重力位场的界面反演是位场处理解释中的重要问题.本文针对重力密度界面的反演问题,较全面的介绍了一些有代表性的方法,包括空间域反演方法和频率域反演方法.重点阐述了当前占主流的频率域中的Parker-Oldenburg迭代方法,在此基础上讨论了重力密度界面反演目前存在的问题和以后的发展方向.

the gravity interface inversion is an important issues of the processing and interpretation of gravity field. In this paper, we review the current popular inversion method, including the space domain inversion method and frequency domain inversion method. This paper comprehensively introduces some representative methods, focusing on the currently popular Parker-Oldenburg iterative method in frequency domain. Due to the use of the fast Fourier transform, the Parker-Oldenburg method gives faster computation. Finally, we discuss the existing problems and the future direction of development of the gravity density interface inversion. A priori information may also be added into the iteration process （e. g. the depth of the known point, the upper/lower limit of the density, etc. ） to minimize the number of possible solutions of the potential field inversion.
