山东中部全新世环境演变与人类文化发展

全新世环境演变及其气候事件对古文化发展的影响是目前环境考古研究的热点。根据山东中部龙山镇山城村全新世黄土-古土壤及埋藏文化层的关系,利用色度、磁化率、粒度、碳酸钙含量等气候替代指标,揭示了全新世气候演变,早期(11500 a B.P.～8500 a B.P.)变暖,中期暖湿(8500 a B.P.～3100 a B.P.)和后期(3100 a B.P.以来)逐渐转凉,其中大暖期记录了3次气候寒冷事件。通过分析全新世气候阶段性、气候事件与古文化时空的耦合关系发现:在全新世最为暖湿的阶段(8500 aB.P.～4000 a B.P.),依次发展了后李文化、北辛文化、大汶口文化和龙山文化。其中,8200 a B.P.、5500 a B.P.气候事件没有对文化发展产生明显负面影响,反而对文化发展起了一定催化剂的作用。4000 a B.P.气候事件在剖面中表现明显,来自北部、东北部的大量风沙使淄博、潍坊等地龙山人的生存环境急剧恶化,进而使喜暖湿的稻作农业受到极大摧毁,人地资源矛盾突出,导致优秀的龙山文化被古朴的岳石文化所取代。

Holocene Environmental Change and Its Impacts on Cultural Development in the Central Region of Shandong Province

It is a research focus of environmental archaeology that the influences of Holocene environmental changes and climatic events on the development of ancient culture.Based on the relationship between Holocene Loess-paleosol sequence and ancient cultural layer of soil buried at Shanchengcun profile in central Shandong,the soil chroma,magnetic susceptibility,grain size,calcium carbonate and other climatic proxy were utilized,and the evolution of Holocene climate was revealed: it got warmer at the early stage(11...
