摘　　要：分析了直流电测深法(VES)与中心回线瞬变电磁法(TEM)对地层的响应特征,结果显示:TEM对低阻层反应灵敏,而VES对高阻层具有较高的分辨能力。基于TEM与VES对地层响应特征互补的特点,尝试将TEM与VES数据进行联合反演,模型试算结果表明,联合反演的效果明显比单一方法反演的效果好。This paper deals with the layer response characteristics of VES （Schlumberger configuration） and TEM （central loop configuration） through the forward modeling procedure, and the results show that TEM is more sensitive to the low resistivity layer and VES is more sensitive to the high resistivity layer. Based on the response characteristics, the paper then tried to do inversion of combined VES and TEM data, and the model inversion trial indicates that the inversion result is better than the result of single TEM or VES data inversion.
