Abstract Understanding Holocene paleoclimate in arid Central Asia (ACA) is helpful for predicting future climate. However, Holocene climate patterns and their forcing mechanisms across ACA are vigorously debated in the context of global climate change. Here, we present a Holocene loess profile (SGX) from the Ili Basin in the Westerlies-dominated Central Asia. Based on high-resolution, medium-grained (38–63 μm) quartz optically stimulated luminescence (OSL) dating, and grain size and color measurements, we reconstruct the Holocene paleoclimate. OSL geochronology indicate that this SGX loess profile covers the last 11.5 ka, and grain size analyses reveal that the sediments are sandy loess, and the environmentally sensitive fractions are

伊犁盆地全新世尘埃沉积及其对西风主导的中亚气候变化的影响

摘要 了解中亚干旱地区（ACA）全新世古气候有助于预测未来气候。然而，在全球气候变化的背景下，ACA 的全新世气候模式及其强迫机制引起了激烈的争论。在这里，我们展示了西风带主导的中亚伊犁盆地的全新世黄土剖面 (SGX)。基于高分辨率、中等粒度 (38–63 μm) 石英光学受激发光 (OSL) 测年以及粒度和颜色测量，我们重建了全新世古气候。OSL 年代学表明该 SGX 黄土剖面覆盖了最后 11.5 ka，粒度分析显示沉积物为砂质黄土，环境敏感部分为
