摘　　要：随着人类需求的不断提高和对自然资源的依赖,气候变化已成为影响人类生存和发展的主要制约因素之一.本文以华北地区为例,讨论了4 200aBP前后气候突变事件及其造成的社会响应.通过分析多个气候替代指标发现,此时气候的干冷突变使得华北地区新石器文化衰落,农业文明急剧衰退,农业结构发生转变,旱作农业占据主导地位,草原畜牧业得以发展,社会分层逐渐出现.今后的研究需要进一步整合考古资料和高分辨率古气候记录,缩小测年误差,突出气候模型输出,深化对气候突变过程的理解,更好地应对未来的气候变化.With the increasing demanding and dependence of natural resources,climatic changes tend to be a major constraint on the livelihood and development of human beings.In this paper,taking the north China region as an example,the proxy records of climate change and societal responses at about 4 200 a BP are discussed,and some coping strategies are put forward.Through the analysis of multiple climatic indexes,a drastic shift in climate is found that has substantially undermined the resilience of the agriculture-based society,caused a sharp decline of agricultural civilization and the change of agricultural structure in North China,which was ultimately replaced by the grassland-based animal husbandry and millet dominated agriculture,thereby leading to the emergence of a hierarchical society.Additional work is needed in the future to integrate archaeological data and high-resolution palaeoclimate records,reduce the dating error,highlight the output of climate models and deepen the comprehend of climate catastrophe process,which is of great significance to the future climate change.
