【摘要】：梁王城遗址地层孢粉、质量磁化率、粒度和Rb/Sr等多环境替代指标分析结果表明该区在大汶口文化产生之前是冷湿的气候环境,大汶口文化时期气候与环境条件好转,略显温暖湿润,但也有较大的波动。西周文化时期,气候整体上较温暖湿润。但在中期出现冷干事件,之后又变暖湿,到晚期又转为冷干,体现出不稳定的气候环境。战国时期,较西周时期气候适宜。前半期较暖湿,后期较冷干,但总的看来,气候属于人类适宜期。北朝时期,早期较暖湿,人类栽培作物花粉含量相对较高,晚期转凉干,有显著的冷干事件。宋朝时期总体看气候环境较适宜,但气候异常事件较多。明清时期孢粉浓度整体较高,但中期较低,木本百分含量也增加,体现出较好的气候条件,但也有波动。孢粉数据显示在本遗址地层中,人类大规模栽培植物可能是从西周开始的。
[Abstract]:The results of multi-environmental substitution indexes such as sporopollen, mass magnetic susceptibility, particle size and Rb/Sr in Liangwangcheng site indicate that there was a cold and wet climate environment in this area before the emergence of Dawenkou culture, and the climatic and environmental conditions were improved during the period of Dawenkou culture. Slightly warm and humid, but there are also larger fluctuations. During the Western Zhou culture period, the climate was warmer and wetter as a whole. However, the cold and dry events occurred in the middle period, then became warm and wet, and then turned to cold and dry in the late stage, which reflected the unstable climate environment. During the warring States period, the climate was more suitable than the Western Zhou Dynasty. The first half is warm and wet, the latter is cold and dry, but generally speaking, the climate is suitable for human being. In the Northern Dynasty, the early period was warm and wet, the pollen content of cultivated crops was relatively high, and the late stage turned to cool and dry, there were significant cold and dry events. During the Song Dynasty, the climate environment was more suitable, but there were more abnormal climate events. During the Ming and Qing dynasties, the sporopollen concentration was higher as a whole, but lower in the middle period, and the percentage content of woody also increased, which reflected better climatic conditions, but also fluctuated. Sporopollen data show that in the strata of the site, large-scale cultivation of human plants may have started in the Western Zhou Dynasty.
