通过对河南二里头文化遗址区内含文化层和自然剖面的土壤化学成分(有机碳、全氮、全磷、有机磷)的含量及变化趋势进行对比分析,研究二里头文化时期该地区人类活动对土壤化学成分的影响。结果表明:研究地点二里头时期的人类活动对含文化层土壤化学成分产生了明显影响,土壤中有机碳、全磷和有机磷含量明显增加,人类活动还使土壤中元素含量的比值发生了明显变化,W(OP)/W(TP)明显增加,元素含量和比值变化特征说明研究地点为古人类生活居住区。
Through the comparative analysis of the chemical composition (organic carbon, total nitrogen, total phosphorus, organic phosphorus) and the change trend of soil chemical composition (including organic layer and natural section) in Erlintou Cultural Relics Site in Henan Province, Impact on soil chemical composition. The results showed that human activities in Erlitou period had a significant effect on the chemical composition of soil with culture layer. The content of organic carbon, total phosphorus and organic phosphorus in soil increased obviously, and the ratio of element content in soil was also obvious Changes, W (OP) / W (TP) increased significantly, the element content and the ratio of changes in the characteristics of the study site for the ancient human living area.
