对布格异常采用小波变换场分离技术得到深部重力异常 ,利用其他地球物理方法获得较可靠的先验信息作为约束 ,并采用球谐函数的级数解形式对中国东部及其邻域的深部重力异常进行联合反演 ,获得了该区岩石圈底界面的展布图像 ;同时对岩石圈底界面特征和强地震分布特性进行了讨论 ,指出中国东部及其邻域在地貌分布、各种地球物理场和岩石圈结构等方面都明显地具有分区性 ,很可能与深部岩石圈底界面的变化有关 ,而岩石圈底界面的形态的差异将对岩石圈层的运动和一系列地质过程产生重要作用 ,强地震活动的分布也与深部岩石圈界面形态和构造环境密切相关 The deep gravity anomalies are obtained by the wavelet transform field separation technique for Bouguer Abnormity, the more reliable prior information is obtained by other geophysical methods as constraints, and the deep gravity of the eastern part of China and its adjacent regions Anomalous joint inversion was performed to obtain the distribution images of the lithosphere bottom interface in this area. At the same time, the characteristics of the lithosphere interface and the distribution characteristics of strong earthquakes were discussed. It is pointed out that the distribution of geomorphology, geophysics The field and lithosphere structure obviously have zoning, which is probably related to the change of the deep lithosphere bottom interface. The differences of lithospheric interface morphology will have an important effect on the lithosphere movement and a series of geological processes The distribution of strong earthquakes is also closely related to the morphology and tectonic environment of the deep lithosphere interface
