冀东地区地处内蒙古高原、东北平原、华北平原的中间地带,是游牧文化和中原文化的过渡地带,在文化发展与传承中占有特殊地位。本文以冀东地区新石器时代至青铜时代聚落遗址为研究对象,利用ArcGIS软件和该地区30 m分辨率的SRTM DEM数据,建立了新石器时代到青铜时代冀东地区815个古聚落遗址的GIS数据库,对冀东地区聚落遗址分布密度、分布重心进行了分析,探讨了海拔高程、坡度、距河流远近等环境因子对不同时期聚落遗址分布的影响。结果表明:(1)新石器时代至青铜时代聚落遗址分布的平均密度呈稳步上升的趋势,由新石器时代的10.73×10^-4个/km^2到青铜时代的58.8×10^-4个/km^2;聚落遗址分布重心由燕南丘陵区(30×10^-4-36×10^-4个/km^2)转移到燕北山地地区(195×10^-4-234×10^-4个/km^2);(2)新石器时代到青铜时代聚落遗址集中分布在距河流中心线3 km以内的区域,但青铜时代3km缓冲区以外的聚落遗址比例升高,濒河性呈减弱趋势;(3)新石器时代至青铜时代聚落遗址变迁表现出明显的由低海拔(〈50 m)到较高海拔(500-1000 m),由低坡度(〈3°)到较高坡度(7°-15°)转移的趋势;(4)环境变化对平原地区聚落遗址的影响远大于山区。
Eastern Hebei Province is located in the junction area of Inner Mongolia plateau,Northeast Plain and North China Plain,and is a transitional zone of the nomadic culture and the central plains culture,thus it holds a special position in the development and inheritance of culture. In this paper,based on Arc GIS software and SRTM DEM data with 30 m resolution in the eastern Hebei Province,the geographic information database of 815 archaeological settlement sites were established, distribution density and center of the settlement sites were analyzed,and the influence of environmental factors,such as elevation,slope and distance from rivers,on the distribution of settlement sites were discussed from Neolithic Age to Bronze Age. The results showed that:( 1) from Neolithic Age to Bronze Age,average density of the settlement sites increased from 10. 73 × 10^-4to 58. 8 × 10^-4/km^2,and high density center of the settlement sites transferred from the southern hills area( 30 × 10^-4-36 ×10^-4/km^2) to the northern region of Yanshan( 195 × 10^-4-234 × 10^-4/km^2);( 2) the settlement sites had been concentrated within 3 km buffer zone from rivers in the whole period,but the number and proportion of settlement sites increased for those beyond 3 km in Bronze Age,which meant people's dependence on rivers was reduced;( 3)location of the settlement sites changed from lower elevation( 50 m) to higher elevation( 500-1000 m),and from gentler slope( 3°) to steeper slope( 7°-15°);( 4) the impact of environmental changes on the distribution of the settlement sites in plain area was greater than that in mountainous areas.
