临夏北塬黄土剖面粒度变化及其与全球海面变化的对比数据集（15万年以来）

风成黄土沉积的粒度变化受控于风力强度及大气环流，具有气候学意义。根据临夏北源黄土剖面的粒度资料，结合沉积物的年代测定，研究了粒度参数随时间的变化特征。表明临夏黄土自150ka以来，粒度参数反映的气候变化经历了8个主要阶段，完全可以与南极东方站冰岩芯温度记录及深海氧同位素阶段对比。但气候阶段的始末在时间上有一些差异，可能反映不同气候区域对全球气候变化的响应不同。而粒度参数与全球海面变化却非常一致；海面的升降及温度变化也控制和影响着大陆环流系统。

Grain size variations in eolian loess deposits, governed by wind intensity and atmospheric circulation, hold significant climatological implications. This study examines the temporal variation patterns of grain size parameters using grain size data from the Linxia Beiyuan loess section and chronological dating results of the associated sediments. The results indicate that since 150 ka BP, the climate changes reflected by the grain size parameters of the Linxia loess have undergone eight major stages, which can be fully correlated with the temperature records from the Antarctic Vostok ice core and deep-sea oxygen isotope stages. However, there are slight temporal discrepancies in the onset and termination of these climate stages, which may reflect differing responses of distinct climatic regions to global climate change. Notably, the grain size parameters align extremely well with global sea level changes; sea level fluctuations and temperature variations also exert control over and influence the continental circulation system.
