伊犁地区是新疆重要的黄土分布区之一。黄土的粒度分析结果表明，与东部季风区黄土类似，黄土组成中以粉砂占优势，但伊犁地区的黄土却以砂含量低，细粉砂和粘粒含量高而显著区别于黄土高原的典型黄土沉积和新疆其它地区的黄土，反映西风的远源输送在该区域黄土形成过程中扮演着重要角色，粉尘来自西部荒漠。
Ili region is one of the important loess areas in Xinjiang. The results of particle size analysis of loess show that, similar to the loess in the eastern monsoon region, silty sand is predominant in the loess composition, but loess in the Yili area is significantly different from the loess in the Loess Plateau due to its low sand content and fine silt and clay content Loess deposits and loess in other parts of Xinjiang, reflecting the long-distance westerly wind transport in the loess formation in the region plays an important role in the dust from the western desert.
