The invention relates to a gravity data downward continuation method and system based on compact constraint. The method comprises the following steps: acquiring gravity data of each measuring point in a research area and preprocessing the gravity data; determining geometric parameters of an equivalent source of the research area; density distribution of equivalent sources is obtained based on the preprocessed gravity data in combination with a compact constraint term and a smoothing strategy; the compact constraint term is determined according to the equivalent source density and the compact factor; obtaining an equivalent source model according to the geometric parameters of the gravity equivalent source and the density of the equivalent source; and performing forward modeling calculation based on the equivalent source model to obtain a downward continuation result of the gravity data. By introducing a compact constraint term, the equivalent source physical properties are distributed in ...
