摘　　要：强干扰区进行地球物理探测,尤其是电磁法勘探时,难以获得可靠的、高质量的原始数据;为取得良好的勘探效果,预处理的重要性更加凸显。通过对原始数据的呈现、分析,提出数据预处理的两套方案,并从理论和实际上证实了方案的可行性。最终结合勘探实例,对比两套数据预处理方案,优选全区视电阻率的方法对原始数据进行预处理,并对其预处理数据反演成图,取得了良好的应用效果。In the area affected by strong electromagnetic disturbance, it is difficult to obtain reliable and high-quality original data of geophysical exploration, especially electromagnetic prospecting. So the importance of preprocessing is obvious. Through analysis and display of the original data, we put forward two schemes of data preprocessing, and further confirm the feasibility of the two schemes in theory and practice. Finally combining actual cases, through comparison of two schemes, we concluded that the method of full-region apparent resistivity is better.
