摘要
利用福建中部和东南沿海地区的重力布格异常资料，通过地震与重力３维联合反演所分离的不同层面间的重力异常信息，采用基于单层位理论和球近似条件下的简便公式，解算并分析研究不同壳层间的密度变化分布图像及其特征，结果表明：不同圈层的密度分布特征与地表地质构造密切相关。
By using the Bouguer anomaly data in the middle and southeastern coast of Fujian and the anomalous gravity informotion between the different layers dirived by 3-D combined inversion of earthquake and gravity data, and by the brief formulae based on the single potential theory and under spheric approximation condition the distribution pattern and characteris--tics of density change between different crustal layers are solved and analyzed. The results show that these characteristics of density distribution between different crustal layers are closely correlated to the geological tectonic of the earth surface.
