摘要

摘要: 以青藏高原东南缘甘孜A剖面黄土-古土壤序列为材料,在磁性地层学研究的基础上,对其高分辨率磁化率记录的多时间尺度气候特征进行了分析。磁性地层学研究结果表明,甘孜A剖面典型风尘堆积的底界年龄约为1.16 Ma。磁化率记录在构造时间尺度上具有明显的阶段性,显示了西南季风演化存在中更新世气候转型。功率谱分析检出典型的偏心率100 ka、斜率41 ka、岁差23 ka轨道周期和11.4、7.5 ka的岁差拍頻周期,指示西南季风演化受天文因素影响,印度季风系统对太阳辐射具有非线性响应和热带特征。

Abstract: Climatic characteristics of different stages recorded by high-resolution magnetic susceptibility are discussed based on loess-paleosol sequence of Garzê A section and also on magnetostratigraphy on the southeastern margin of the Qinghai-Tibetan Plateau.Periodicities of the earth's orbital parameters are detected by power spectral analysis and the evolution of the southwest monsoon on orbital time-scale is studied.The results show that (1) the cycle of quasi-100 ka does exsit in the evolution of the southwest monsoon, and the obliquity cycle and precession cycle are remarkably detected as well;(2) the beat frequency periods of the precession are detected and give a strong non-linear response to the solar insolation and the tropical climatic characteristics of the southwest monsoon;(3) the mid-Pleistocene transition which was recognized in the evolution of the southwest monsoon began approximately 0.95 MaBP and ended around 0.6 MaBP.
