点分布建模和可视性分析在长城研究中的应用--以燕长城赤峰段为例

Application of Point Pattern Modeling and Visibility Analysis in the Study of the Great Wall-A Case Study of the Chifeng Section of the Great Wall in the State of Yan

点分布建模和可视性分析是考古学研究中的前沿方法和重要手段。本文结合了这两种方法,对燕长城赤峰段的军事防御体系的内部运作机制进行了研究。第一部分利用点分布建模法探索了烽燧、障城等附属遗址在地形因素影响下的分布规律,并显示了遗址空间分布的层级性。第二部分证明了烽燧的可视性,具体研究了烽燧之间的烽燧信息传输和控制范围,揭示了战国燕长城赤峰段存在着较复杂的军事防御策略。

Point patterm modeling and visibility analysis are the cutting edge methods in the spatial analysis of archaeo-logical study.This paper combines these two methods to study the intermnal mechanism of the military defense system of the Great Wall of Yan state in the Warring States period.In this paper,point pattern modeling is largely used to explore the distribution law of the Great Wall's ailited fortifcations,such as Fengsui(watchtowers)and Zhangcheng(orts),under the infuence of topographic and environmental factors.On this basis,the hierarchical spatial distribution of the sites is well shown.In terms of visibility,this paper specifcally studies the intervisibility among the Fengsui,a well as their controlling areas,which reveals that there were indeed complex military defense strategies within the early Great Wall in the Warring States period.
