摘　　要：根据羌塘盆地重磁震数据资料,使用GM SYS软件系统对重力、磁法及地震位图三种地球物理剖面进行处理解释,共完成4条地球物理剖面的模拟解释,并由其构组羌塘盆地地质-地球物理综合解释栅栏剖面图。地球物理剖面"栅状图"反映了研究区内深层勘探目标的变化趋势和构造特征,为使用重、磁、震资料进行非震地球物理反演提供了约束骨架。若结合研究区内钻孔及其他地质资料,可为盆地进行三维地球物理精细反演提供约束和初始模型。Based on the gravity, magnetic and seismic data from Qiangtang Basin, by utilizing the software GM SYS, the authors interpreted the data including gravity, magnetic method and seismic bitmap for the three kinds of geophysical profiles under simulated condition, and finished four profiles. The profiles are used for constituting a geological and geophysical fence profile, which shows the variation trend and the structural feature of prospecting for deep objects in the study region; meanwhile, it provided a restriction for non-seismic geophysics inversion. If combining boreholes and other geological data from the basin, the restriction and the initial model could be provided for 3D geophysics fine inversion.
