基于ArcGis10.0平台分析了河南省史前时期的仰韶文化遗址和龙山文化遗址的空间分布、濒河性、空间集聚度等指标。结果显示,18.8%的仰韶期遗址分布在河流的1 km缓冲区内,而龙山期遗址只有16.5%,其濒河性呈减弱趋势。豫西山区、南阳盆地...基于ArcGis10.0平台分析了河南省史前时期的仰韶文化遗址和龙山文化遗址的空间分布、濒河性、空间集聚度等指标。结果显示,18.8%的仰韶期遗址分布在河流的1 km缓冲区内,而龙山期遗址只有16.5%,其濒河性呈减弱趋势。豫西山区、南阳盆地、颍河—淮河地区龙山期遗址的空间集聚度比仰韶期分别增加了0.006,0.016和0.021,暗示龙山时期的自然条件逊色于仰韶期导致人类活动范围受到局限。遗址密度3-D分析表明,河南地区史前人类活动格局从仰韶期的"单核型"演化为龙山时期的"多核型"。这种空间格局的变化可能与5.4 ka BP降温事件相关,而且龙山期的气候特征与仰韶时期相比显得温凉、干燥,加之农业生产技术的进步和人口增加促使史前人类活动核心区从豫西山区向豫东平原和豫北平原地区扩散。同时4.0 ka BP前后河南地区的干旱、洪水、低温等自然灾害频发亦加速了人类活动范围的快速扩展,并且石家河、大汶口、关中等史前文化类型向河南地区的渗透,造成河南龙山文化类型的多元化和空间分布的复杂化。而全新世早期的裴李岗遗址和晚期的二里头遗址数目较少且均匀分布于嵩山两翼,初步推测环嵩山地区是河南史前文化的肇源地区。展开更多

Due to spatial distribution of the Yangshao cultural sites, they had a river-oriented trend in comparison with those in the Longshan Period. Apart from terrain factors, distribution of the sites in both periods is subject to paleo-environmental changes. The Yangshao Culture originated in Holocene Optimum Period, and the Longshan Culture started in climatic fluctuations prior to Neolithic ending. But the latter owned more sites and wider scopes than the former did. Both the Cultures devel- oped fast in rich rainfall and warm periods, and withered for abrupt cooling events in 5.4 ka BP and 4.0 ka BP respectively. Therefore, the sustainability of Henan's Neolithic Cultures is not good as expected. Whilst, the ancient farming acted an irreplaceable part in distribution of human sites, and the need for farming space prompted human sites to expand from the western hilly areas towards the eastern plain of Henan. Moreover, the neighboring cultures poured into Henan and complicated the cultural patterns. Besides, characteristics of the sites in the Erlitou Period suggest that some social factors disturbed the spatial pattern at the end of Neolithic age in Henan.展开更多
