利用总有机碳（TOC）、碳酸盐、磁化率、有机碳稳定同位素组成（δ 13 Corg）和粒度分布等多指标，结合加速器质谱（AMS）14 C和光释光（OSL）方法测定的年代，推断了四川北方黄土沉积物全新世中晚期的气候波动。6300 ~ 5500 aBP，区域气候表现为暖湿逐渐增加，降水减少，但气温相对较高，表明东亚季风减弱。4800 aBP以来，全球气候变暖，气候偏湿，3300 aBP左右，由于太阳辐射强迫，出现了一次冷逆转，导致全球气候变冷，冰川前移。青藏高原东缘的大规模人类迁移发生在距今6000、2500和1200 aBP的冷干事件中，表明气候变化对人类迁移具有重要的刺激作用。
The climatic fluctuations during the mid-late Holocene in northern Sichuan, southwest China, were inferred from loess deposits using multi-proxies of total organic carbon (TOC), carbonates, magnetic susceptibility, stable isotopic composition of organic carbon (δ13Corg) and grain size distribution in combination with the dates determined by the accelerator mass spectrometry (AMS)14C and optically stimulated luminescence (OSL) methods. From ∼6300 to 5500 a BP, the regional climate presented gradually increased warmth and humidity, subsequently characterized by reduced precipitation but with relatively high air temperature between ∼5500 and 4800 a BP, demonstrating that the East Asian monsoon weakened. A warmer and wetter climate prevailed since ∼4800 a BP and was interrupted by a sharp cold reversal at approximately 3300 a BP that was likely caused by solar irradiance forcing, which resulted in a global cold climatic change and glacier advance. Large-scale human migrations into the eastern margin of the Tibetan Plateau occurred in the cold and dry events that developed at ∼6000, 2500 and 1200 a BP, indicating a critical stimulus effect of climatic change on human migration.
