| 摘 要： | 通过黄土高原西部平凉剖面的植硅体分析,对黄土高原西部全新世中晚期气候进行研究,将研究时期的气候分为5个阶段:8.43～7.78KaB.P.,气候凉湿;7.78～7.17KaB.P.,气候暖湿;7.17～6.27KaB.P.,气候总体仍为暖湿,但较上带有变冷趋势;6.27～5.55KaB.P.,气候特征为凉湿;5.55～0KaB.P.,气候特征仍为凉湿,但具有偏凉干趋势。明显的气候波动与全新世中晚期全球变化可以对比,与相邻区域的孢粉、粒度、磁化率等研究工作结果较为一致。

| Abstract: | Through the phytolith analysis of Pingliang profiles in the western Loess Plateau,the Holocene Paleoclimate of the western Loess Plateau was studied.The climate period can be divided into five stages:8.43~7.78 KaB.P.,cool and wet climate;7.78~7.17 KaB.P.,warm and humid climate;7.17~6.27 KaB.P.,still warm and humid climate in general,but with a cooling trend compared with the previous;6.27~5.55 KaB.P.,the climate was characterized by cool and wet;5.55~0 KaB.P.,still cool and wet climate characteristics,but with a slightly cool and dry trend.Significant climate fluctuations and global change in the late Holocene compared with the adjacent region of pollen,grain size,magnetic susceptibility and other research results were more consistent. |
