本文通过解决多层密度界面反演的不适定性问题，使得应用重力对多层界面的反演成为可能。在只有少量地震或钻井深度点控制的地区，应用该方法进行反演，可对地下各层界面的起伏有一个宏观的认识，为进一步勘探部署提供依据。
By solving the ill-posed problem of multilayer density interface inversion, this paper makes it possible to use gravity inversion of multi-layer interface. In the area with only a few earthquakes or drilling depth control, applying this method to inversion can provide a macroscopic understanding of the fluctuation of the interface of underground layers and provide the basis for further exploration and deployment.
