良渚遗址古水系调查中的综合地球物理方法

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.

Integrated geophysical survey for palaeo-drainage system at Liangzhu sites

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.
