为探明晋阳古城不同赋存类型城墙遗址的地球物理特征及遗存状态，研究综合地球物理方法勘查古城墙的有效性及最优组合方案，为此采用磁法、高密度电阻率法、探地雷达法、γ能谱法对晋阳古城二三种不同类型的古城墙进行了勘查；结合二维及三维的数据处理方法及显示手段对城墙遗址进行定性及定量描述；探讨多方法勘查成果的集成解释方案，并在此基础上总结出了不同类型城墙遗址的地球物理模型及相应的最优勘查方法组合：对西城墙，采用高密度电阻率法和探地雷达法；对东南城墙，采用磁法和高密度电阻率法；对北城墙，采用高密度电阻率法和探地雷达法本研究结果可为晋阳古城遗址下一步的开发保护工作提供技术依据，也可为同类探测工作的开展提供指导作用.

英文摘要：

In order to determinethe geophysical characteristics and physicalstate of the ancient city walls, which areunder different conditions, and to exploretheeffectiveness ofan integrated method to visualizeancient city walls, A survey using a variety of methods was conducted. It included, primarily, electric resistivity tomography （ERT）, magnetometry （MAG）, ground penetrating radar （GPR） and γ- rayspectrometry. Combining thesegeophysical method results with 2D and 3D data processing and display technology, the location and the geophysical characteristics of the ancientcitywalls were successfully detected. To reduce ambiguity in interpretation, approaches to integrating multidimensional geophysical data were also examined. Finally, the geophysical models of the different walls were summarized, and optimal combination methods for further study were proposed. These includeERT and GPR for the west wall, MAG and ERTfor the southeast wall and ERT and GPR for the north wall. The results show that application ofintegrated geophysical methodsis the preferred technology for the archaeological exploration of the ancient city walls.
