摘　　要：通过分析研究沙拉西别铁铜矿区上方不同高度航磁ΔT特征,认为飞行高度是影响航磁分辨力的关键因素,ΔT极值随高度变化的衰减曲线是不同深度、不同形态、不同地质体等各种磁场衰减组分的叠加,对航磁飞行高度质量控制具参考意义,对从空间磁场分布规律来研究目标地质体提供一种思路。The paper analyzed the aeromagnetic △T feature with different flight clearance over Shalaxibie iron copper mines, the flight clearance is the key factor to influence the aeromagnetic Survey discriminability, deduce that the △T extremum attenuation curve are composed with different depth, different shape, different geologic body etc all kinds of magnetic attenuation components, it is a meaningful reference to controlling flight clearance quality in aeromagnetic survey, it provide an method to study Objective geologic body from magnetic field spatial distribution rule.
