地质学在关注人类活动的环境效应——兼谈黄河三角洲剖面炭屑分析与人类活动

Geologist′s Concern over Environmental Effect of Human Activities——With Reference to Charcoal Fragment Analysis for the Yellow River Delta

人类活动的环境效应,很多大的国际研究计划都给予充分重视。炭屑分析是研究历史上人类活动的方法之一。黄河三角洲剖面炭屑分析,从自然变化背景中分离出了因人口增长和火灾造成的5个炭屑高峰值。这一结果说明,精细的高分辨率的研究工作,是探讨历史上人类活动环境影响因子的前提。

Many international programs have placed emphasis on the environmental effect of human activities,and the charcoal fragment analysis is one of the methods for studying the historical human activities.The analysis method was used to separate five charcoal fragment peak values due to population growth and fire disaster from the natural variation background in the Yellow River delta area. The analysis results indicate that the high-resolution studies are the prerequisite for exploring the environmental impact factors of historical human activities.
