///In this paper, the authors reconstruct the history of climate change since the last glaciation by analyzing the grain size of Zhaosu section loess. The result shows that the content of grain size >63 μm can be well compared with the records of Greenland ice core that the climate fluctuations of the global significance such as Heinrich events and the Younger Dryas cold event as well as D-O cycles, reveals the Central Asian’s climate changes with the global features of millennial scale and high frequency oscillation since the last glaciation. The analysis of grain size indicates that the loess grain size distribution of the Ili region is similar to that of the Chinese Loess Plateau, dominated mainly by silt, but the contents of sand in the Ili loess is lower and fine clay higher, which is different from those of the Chinese Loess Plateau.
