Hujiagang is located in Yingxian, Shanxi Province. The river terrace in Hujiagang was formed between 66.46 ka and 33.62 ka. The grain-size distribution characteristics were used to interpret the deposit environment of Hujiagang river terrace. The grain-size distribution characteristics are discussed in this paper. The strata in Hujiagang river terrace in general are formed in fluvial facies and the top is alluvial plain sediments. The change of these grain-size distribution characteristics is in accord with the oxygen isotope variation of Guliya ice core, thus the change of grain size and the deposit environment of Hujiagang river terrace are controlled by the climate change.
