【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。
[Abstract]:The restoration of the ancient land Silk Road is an important part of the study of the Silk Road.In this paper, based on 30m resolution SRTM data, the key terrain factors and hydrological factors which have important influence on the formation of ancient roads are extracted, and the route cost data are generated according to a certain cost ratio.Combined with the distribution data of rivers and lakes in the region and the key station data along the ancient land Silk Road recorded in relevant literature, the method of optimal path analysis is applied to restore the ancient land Silk Road step by step. Finally,The piecewise route was merged by iterative analysis and the complete ancient land Silk Road from Chang'an to Constantinople across Eurasia was obtained.On this basis, combined with the MODIS remote sensing image data and the population and economic statistics of the relevant countries along the route, the main geographical elements along the ancient land Silk Road are analyzed.In order to understand the ancient land Silk Road along the basic human, physical and geographical characteristics.
