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。The four different prehistoric settlement site groups can be recognized as spatio-temporal objects.The spatio-temporal data model of settlement groups is established based on the object-oriented.From the evolution of center point and solution speed of the settlement site groups,combined with the areas of various periods of the settlement groups,the number of ruins,density of ruins,the paper analyzes the spatio-temporal evolution of the prehistoric settlement site groups among ZhengzhouLuoyang area.The results indicate：1）From the development and merging of settlement site groups,there was no difference between Peiligang period and the early stage of Yangshao period.The settlement site group became East-West Confrontation in the last period of Yangshao period.The Longshan period was grading obviously and the central settlement site group began to taking shape.2） The center of four consecutive cultural periods was moving to southwest rapidly at first,then moving to northeast and the speed was increasing from slow to fast.3） The average density of four consecutive periods was on the rise and the first three periods were rising slowly while the Longshan period increased significantly.
