摘　　要：首先应用MATLAB语言,编制了多边形法计算基底界面深度的程序,计算了一条基底界面深度。以区域地质资料和物性资料为依据,对黑龙江省虎林市幅1∶20万重磁场进行了综合分析。根据虎林盆地布格异常和区域场特征,结合重力异常和航磁异常等综合资料,按结晶基底起伏状态,将虎林盆地划分为3个隆起区,2个凹陷区。应用Sufer软件以及3D成图技术恢复出盆地基底起伏界面全貌。The paper first apply MATLAB language programming a procedure of calculating the depth of interface basement and calculates the depth of one basement interface.A comprehensive analysis is made on the characteristics of gravity and magnetic anomaly on 1∶200 000 map-area of Hulin City in Heilongjiang Province according to the geological and geophysical data.According to the characteristic of Bouguer gravity and regional gravity anomaly,and by the study of synthetic data of aero-magnetic and gravity anomalies ...
