摘要
古陆上丝绸之路的路线复原是丝绸之路研究的重要组成部分,但目前该方面的研究还缺乏全局性、整体性的视角。该文首先基于30m分辨率SRTM数据提取了对古代道路形成产生重要影响的关键地形因子和水文因子,并按照一定成本比率生成路线成本数据;然后,结合该区域的河流湖泊分布数据以及相关文献记载的古陆上丝绸之路沿线关键驿站数据,应用最优路径分析方法逐段复原古陆上丝绸之路;最后,应用迭代分析法对分段路线进行合并,模拟得到完整的从长安到君士坦丁堡、横跨亚欧大陆的古陆上丝绸之路。在此基础上,结合MODIS遥感影像数据以及沿线相关国家的人口、经济统计数据,分析了古陆上丝绸之路沿线主要地理要素特征,以期能较为全面地了解古陆上丝绸之路沿线基本人文、自然地理特征。
The restoration of the ancient Silk Road on land is an important part ab^^ut the study of the Silk Road,but the re-search about this field still lacks the overall and global perspectives.This paper plan to solve these problems from three aspects.Firstly,based on Shuttle Radar T opography M ission(SRTM)data of30m resolution,the key topographic and hydrological fac-tors,which have important influence on the formation of ancient roads,are extracted,and the route cost data are generated at a certain cost ratio by using the elements of topographic and hydrological characteristics which respectively are slope,river,fluctu-ation and lakes in this research.Then,combined with the distribution data of rivers and lakes in the research region and the rele-vant key records of the ancient Silk Road,the Distance M apping spatial analysis method(Best Route Analysis method)was ap-plied to restore the ancient Silk Road.Finally,the iterative analysis method is used to simulate the ancient Silk Road by using segments from Chang an to Constantinople across the Eurasian continent.On this basis,combining with the Moderate-Resolu-tion Imaging Spectro radio meter(MODIS)data,national population data and economic statistics,the paper analyzes the geo-graphical space distributing pattern of the main elements along the ancient Silk Road,in order to have more comprehensive and profound understanding on the basic cultural and natural geographical features along the ancient Silk Road.
