摘　　要：为了快速查明良渚古城外古水系及文化堆积层的分布特征,进而揭开良渚古城所依赖的地理环境背景的面纱.运用综合地球物理方法进行调查研究,包括磁法、高密度电法、探地雷达和放射性测量等.对这些方法的研究结果进行综合对比,形成最终的地球物理解释结果,并将该结果与钻探资料进行对比验证.野外地球物理探测结果表明:这些地球物理方法对古水系沉积和文化堆积层均有较明显的反映,探测结果与钻探结果较好地吻合,说明地球物理方法是有效、可行且经济的考古勘探方法.研究结果也表明,多种地球物理方法互相对比、验证,有利于对异常目标的识别和判断.It was brooky and swampy in ancient Liangzhu city about 5 000 years ago. In order to rapidly investigate the distribution of palaeo-drainage system and the range of remains layer in Liangzhu city-site and further to reveal the background of the geographical environments, several geophysical methods, such as magnetic, electrical tomography, ground-penetrating radar （GPR） and radioactivity survey, were employed. Most of the geophysical methods showed obvious anormalies in palaeo-drainage systems and the remains layers, and the anormalies were consistent with the drilling results. The survey results show that palaeo-drainage system and the remains layer can be distinguished by these integrated surveys and interpretations All these indicate that geophysical methods are effective, feasible and cost-efficient for archeological exploration and the integrated geophysical methods are useful to identify and verify the archeological anomaly in some cases by comparison and validation.
