摘　　要：运用统计学理论,实现对不同勘探地球物理场的综合,并对其综合效果进行评价。数据试验结果表明,综合反演结果的方差比由单一地球物理场得到的该界面深度值的方差要小得多。利用重力场、磁力场和大地电磁场资料,在浅地表覆盖火成岩地区进行综合应用研究,得到了丰富的反映地质结构的信息。The integration of different exploration geophysical fields is accomplished and its integrated effect is evaluated by using a statistical theory. The result of data testing shows that the variance of comprehensive inverse results are much less than that of interfacial depth value obtained with single geophysical field. A study of integrated application is conducted on a shallow surface covered with igneous rocks by using the data from gravitational, magnetic and magnetotelluric fields, abundant information reflecting geophysical structures is obtained.
