摘　　要：密度界面的反演是地球物理勘探的重要课题之一,对研究盆地、区域构造和深部构造有重要意义.本文采用一种密度界面上已知若干控制点深度的迭代反演法,对二维单一密度界面的起伏模型进行计算及讨论,并对大港地区的实测剖面进行反演,取得了较为理想的效果.The inversion of density interface is an important task in geophysical prospecting. It has great values in ba- sin research.regional tectonics and deep structure. An inversion method of two-dimensional mono-density interface with several known control points is presented in this paper. We test the method by a given model ,and make a discussion. Then we implement the method to inversion of a gravity profile measured in the Dagang area , and obtain an ideal result.
