项目摘要

There are several purposes for applying geophysical prospecting methods in archaeological research :1) To define the area of ancient palace, local government, temple and settlement sites, which occupy large spatial areas by using geophysical prospecting methods effectively and precisely. For archaeological research and excavation on these sites, it is difficult to identify the boundaries and inner structure by using common excavation procedures, becouse of the immense amount of time required to excavate such large areas, as well as from limitations of excavation budgets. For geophysical surveying to be able to map the subsurface archaeology, contrasts between the surrounding subsoils and the archaeological targets is required.The physical phenomena which geophysical equipment can measure contrasts in subsurface materials include soil resistanse, susceptibility, dielectric and conductivity (ehich is important in the reflection and attenuation of microwaves).2) To identify the location where bronze objects, common in Yayoi period, are buried randomly within a site. Because of these archaeological conditions, it is difficult to estimate the exact location where the artifact is buried by simple observation of the ground surface. To help the research of those wide area archaeological sites and to locate bronze artifacts, geophysical surveying methods such as resistivity, magnetometry, GPR (ground penetrating redar) and electromagnetic method (EM) were employed in this program to accomplish the research objective.A final conclusion based on the research indicates that it is important to employ GPR first for identifying subsurface structures and to apply resistivity and magnetometry method as a way to corroborate the results first recognized in the GPR survey. For locating bronze artifacts, the EM method is effective, and GPR,resistivity, magnetometry can provide the additional information for understanding the location where they are buried.

在考古研究中应用地球物理勘探方法有几种目的：1）定义古老的宫殿，地方政府，寺庙和定居点的区域，这些区域通过有效，精确地使用地球物理勘探方法占据了很大的空间区域。对于这些站点上的考古研究和发掘，很难通过使用常见的发掘程序来识别边界和内部结构，这是因为挖掘如此大面积所需的巨大时间以及开挖预算的限制。为了使地球物理测量能够绘制地下考古学，需要对周围的地下和考古目标之间的对比。地球物理设备可以测量地下材料中的物理现象衡量的物理现象包括土壤抗性，易感性，介于介意性和电导率（EHICH）在反射和电导率上很重要（EHICH对位置和近距离的位置）。 Yayoi时期被随机埋在站点中。由于这些考古条件，很难通过简单地观察地面掩埋伪影的确切位置。 To help the research of those wide area archaeological sites and to locate bronze artifacts, geophysical surveying methods such as resistivity, magnetometry, GPR (ground penetrating redar) and electromagnetic method (EM) were employed in this program to accomplish the research objective.A final conclusion based on the research indicates that it is important to employ GPR first for identifying subsurface structures and to apply resistivity and magnetometry method as a way to证实了GPR调查中首先认可的结果。为了定位青铜器，EM方法是有效的，GPR，电阻率，磁力测定法可以提供其他信息，以了解其被埋葬的位置。
