摘要
史前人口的估算对于了解人类社会发展具有重要意义。青海东部史前文化遗迹丰富、序列完整。文中根据考古资料和GIS工具,构建墓葬和遗址面积两种模式来计算青海东部史前人类分布的密集区和核心区人口数量,提出以不同方法计算结果为主,辅之以社会与环境因素的考量综合人口估算模式,来研究区域史前人口变化。结果表明:研究区人口在新石器伊始就具一定规模,达到7600余人;新石器晚期人口达到最大值,当时人口约为36000人,4000aBP以后人口数量锐减,进入青铜时代,人口规模略有恢复,达到12000人左右;环境变化应该是本区人口演变的重要驱动力之一。
Prehistoric population estimation has a significant meaning for understanding the development of human society.Prehistoric cultural sites are rather rich in eastern Qinghai,and with an intact sequence.According to archaeological data and GIS tools,we built the tombs and ruins＇ dimension models to calculate the population distribution in core areas and dense areas of prehistoric culture in east Qinghai,and proposed different method results mainly supported by social and environmental considerations in comprehensive population estimate model to study the changes of regional prehistoric population.The results showed that the population hed reached more than 7,600 people at the very beginning of the Neolithic.The population reached its maximum of 36,000 at the late Neolithic.The sharp drop of the population came just after 4000 aBP.When it steped into Bronze Age,the population showed a slight recovery,and reached about 12,000;Environmental change should be one of the important driving forces to evolution of the population in this area.
