洛阳王湾遗址文化地层的古环境与人类活动的关系

Relationship of Paleo-environment and Human Activity Recorded by the Strata of Wangwan Site in Luoyang

  • 摘要: 测试了洛阳王湾遗址地层的粒度、频率磁化率和指示人类活动的重金属元素含量.结果显示,龙山文化层样品主要以粉砂质黄土为主,频率磁化率低值(均值11.9%)和Rb/Sr低值(0.64)表明研究区域在龙山早期(王湾三期)为强冬季风支配下的弱化学风化环境,风尘堆积作用相对活跃.二里头文化期的沉积物主要成分为黏土,频率磁化率较低值(均值12.3%)和Rb/Sr (0.81)反映了夏季风较强而冬季风较弱的暖湿其后条件下的风化环境.与之对应,二里头时期以用火为代表的人类生产和生活活动强度明显高于龙山文化时期,同时生产工具也较龙山时期有所进步,而且聚落的人口规模亦有增加.表明史前时期的人类活动与气候条件有较大的关联性.

     

    Abstract: Using the environmental proxies of grain-size, frequency susceptibility and content of heavy metal element, the relationship of human activities and paleo-environment of the Wangwan site in Luoyang is discussed. The results show that the samples of the Longshan culture layer are mainly deposited with silty loess, and the lower value of frequency susceptibility (mean 11.9%) and the lower value of Rb/Sr (0.64) indicate that the region was dominated by strong winter wind in the early Longshan period (phase III of Wangwan site), and the wind dust accumulation was of prevalence. Clay is the main components of layer in the Erlitou culture period. The climate was warm-wet by indicators of the higher frequency susceptibility (mean 12.3%) and higher values of Rb/Sr(0.81) reflecting a strong summer monsoon. Correspondingly, the high intensity of human activities represented by the fire regime in the Erlitou period contrasted to the Longshan period. And, the tools were also improved from the Longshan to the Erlitou period.
