【摘要】：依据面向对象的思想,建立聚落群对象时空数据模型,对聚落遗址群分别求取中心点和面积,进而得到中心点的演变速度、轨迹和聚落群遗址密度,在此基础上分析郑洛地区史前聚落群时空演变规律。结果表明:1)从聚落群合解历程看,裴李岗时期、仰韶前期几乎无分化,仰韶后期东西对峙,龙山时期分级明显,中央聚落群初现规模;2)4个时期聚落群中心点先向西南快速移动,然后向东北移动,速度由慢到快;3)聚落群遗址密度呈上升趋势,前3个时期上升缓慢,龙山时期上升明显。
[Abstract]:According to the object-oriented idea, the object space-time data model of settlement group is established, and the center point and area are obtained respectively, and then the evolution speed, trajectory and site density of settlement site are obtained. on this basis, the temporal and spatial evolution law of prehistoric settlement group in Zhengluo area is analyzed. The results show that: 1) in the Pei Li Gang period, there was almost no differentiation in the early Yangshao period, the east and west confrontation in the late Yangshao period, the classification of the Longshan period was obvious, and the initial scale of the central settlement group was obvious; 2) the central point of the settlement group moved rapidly to the southwest and then to the northeast, from slow to fast; 3) the density of the settlement sites increased slowly in the first three periods, and increased obviously in the Longshan period.
