全新世中国北方人类活动与气候变化

On the Human Activities and Climate Change of Holocene in North China

以发表的中国北方史前文化遗迹的14 C年代数据为依据,作为指示人类活动强度的指标,并统一校正为日历年,按照百年分段分区进行统计整理,发现:11.5～8kaBP为第一阶段,中国北方人类活动较弱;第二阶段为8～4kaBP,人类活动持续增强,在4kaBP前后达到顶峰;4～3kaBP人类活动记录有所下降。聚类分析表明,中国北方全新世人类活动可以分为北方亚区、河南和陕西3类,北方亚区人类活动在4kaBP达到鼎盛,随后开始衰落,这一衰落与当时季风强度迅速衰弱有关;季风衰弱后的3.6kaBP河南成为活动中心,这一演变规律与中国早期国家夏商活动中心地演变密切相关。

We take it as human activity intensity index instructions based on the published 14C s data of remains of prehistoric culture in the north of China, which unified correction for calendar year according to one hundred year statistics section partition finishing. The following research results were found that.. 11.5-8 kaBP for the first stage, human activity is weak in north China; the second phase is 8-4 kaBP, human activity increase until 4 kaBP peak; 4- 3 kaBP human activities record fell. And through the clustering analysis shows that, the human activities of the Holocene China can be divided into monsoon edge, Henan and Shaanxi three kinds; 4kaBP the human activities to achieve the monsoon edge heyday, then began to decline for the weak monsoon debilitated rapidly; 3.6 kaBP, the Henan become activity center after the monsoon is weak. This evolution pattern has the same trend with the dynasties activity center of early China.
