西方学者提出的“遗址域”概念架起了从遗址内物质遗存分析到遗址外自然环境分析的桥梁。遗址域界定是后期自然环境分析的重要前提,引起了国内学者的广泛关注,但目前的工作尚未提出定量方法来计算不同地貌环境下的遗址域。以高分辨率DEM和相关学者总结的4种步行速度函数为基础,利用ArcGIS的成本距离工具和栅格计算功能生成了地形因素影响下的2h步行遗址域,并进一步讨论了4种算法的数值分布特征。其中较为合理的算法被应用于官亭盆地的3个典型遗址,以统计不同地貌单元的遗址在步行范围内的宜耕土地供给状况。最后,对遗址域分析的现存问题和未来发展,提出了认识和展望。
Western scholars put forward the concept of “site” to set up a bridge from the analysis of the remains of the remains within the site to the analysis of the natural environment outside the site. The definition of the site of the site is an important prerequisite for the analysis of the later natural environment. It has aroused widespread concern of domestic scholars. However, no quantitative method has been proposed to calculate the site of the site under different landscapes. Based on the four walking velocity functions summarized by high-resolution DEM and related scholars, the 2h walking ruins domain under the influence of the terrain factors is generated by using the cost distance tools and grid computing functions of ArcGIS, and the numerical values of the four algorithms are further discussed Distribution characteristics. The more reasonable algorithm is applied to three typical sites in Guanting basin to count the supply of land under suitable cultivation within the walking range of the different geomorphological units. Finally, some suggestions on the existing problems and future development of site analysis are put forward.
