摘　　要：磁异常的复杂性对资料处理和解释带来了一定的困难,而重力异常相对更为简单、更易处理和解释。通过运用空间域的泊松公式,可以在频率域内推导出由磁异常换算重力异常的计算公式,这种由磁异常换算所得到的重力异常称为磁源重力异常。这里对理论模型的磁异常数据进行了计算与实验分析,并对实际航测的磁异常资料进行了计算与处理,取得了良好的应用效果,表明了磁源重力技术的可行性、正确性和精确性。The complexity of magnetic anomaly will cause some difficulties for the data processing and interpretation.However, gravity anomaly is relatively simple and easier processing and interpretation.We deduce the mathematical formulae of gravity a-nomaly which is converted by magnetic anomaly in frequency domain by using Poisson formula,and this gravity anomaly is called pseudo-gravity anomaly.Next,we put the pseudo-gravity anomaly to the test on the magnetic anomaly data of theo-retical model and the magnetic anomaly by aerial survey with satisfactory results,showing that the method is viable,correct-ness and accuracy.
