摘　　要：瞬变电磁技术(Transient Electromagnetic Method,简称TEM)是近年发展较快并得到广泛应用的一种勘探方法。由于其观测的是二次场,可在近区观测,对低阻含水体反应灵敏,而且体积效应小、纵横向分辨率高,施工也很方便、快捷,所以效率很高。将该方法利用在贵州省兴义市清水河镇发大地下水勘查中,勘查效果极佳,所得成果接近真实,故提出将瞬变电磁法可以作为浅层水文地质勘探的重要手段。The Transient Electromagnetic Method(TEM)is a rapidly developing and widely used exploration method in recent years.Due to its observation of a secondary field,it can be observed in close range,Sensitive to low resistance water bodies,moreover,the volume effect is small,the vertical and horizontal resolution is high,and the construction is also very convenient and fast,so the efficiency is very high.This method was applied in the groundwater exploration of Fada in Qingshuihe Town,Xingyi City,Guizhou Province,and the exploration results were excellent,with results close to reality,Therefore,it is proposed that TEM can be an important means of shallow hydrogeological exploration.
