摘　　要：随着航空磁测勘查系统的进步,数据处理解释水平的提高以及航空磁测应用领域的不断拓宽,1994年颁布的航空磁测技术规范中对飞行高度的要求需要根据当前航空磁测的技术与应用实际情况进行调整.本文从理论上分析了二度体和三度体模型磁异常与航空磁测飞行高度的关系,结果表明,可以通过适当加密测线增大测量比例尺的方式,弥补由于提高飞行高度而损失的弱磁异常信息,这对在我国西部地形复杂地区开展航空磁测具有指导意义.As the development of the aero-magnetic survey and the data processing and interpretation, as well as the extent of the applying fields, the requirement of flight altitude in Aero-Magnetic Surveying Criterion which was issued in 1994, needs to be modified according to the current aero-magnetic surveying techniques and practical situation. This paper analyzes the relationship between the flight altitude of aero-magnetic survey and the magnetic anomaly generated by 2-D or 3-D body. The result is that increasing the density of surveying lines （enlarging scale） makes up for the information of magnetic anomaly which loses by increasing flight altitude, which is a meaningful guidance on aero-magnetic survey of complex terrain in Western China.
