使用ArcGIS地理信息系统平台中的叠置分析、表面分析、缓冲区分析等工具,对比吉林省东部地区高句丽、渤海国遗址的位置、类型分布及遗址所在地的高程、坡度、坡向、河流缓冲区分布,可以析出两历史时期遗址在位置、类型分布上的差异性及遗址所在地在高程、坡度、坡向、河流缓冲区分布上的相似性,并就遗址位置、类型分布的差异,说明其主要影响因素。其中,影响遗址位置分布差异的主要因素是两历史时期的行政区划;影响遗址类型分布差异的主要因素是两历史时期的丧葬习俗、文化衍生发展的历史背景及生产方式。
With the form, a comparative application of the tools on Arc GIS Geographic Information System study of ruined sites of Koguryo and Bohai in the east of Jilin ince is made herein to analyze the differences concerning the site locations and types, Plat- Prov- and the similarities concerning the site elevations, gradients, aspects and river buffer areas. The main factors that affect the site locations are the administrative divisions at two historical periods, and those that affect the site types are the funeral customs, the cultural back grounds and the production patterns during the specific periods.
