摘要：

The grain size records of loess in China are some of the most important terrestrial records of past climate changes. It systematically carried out fieldwork on loess section of Xulinzhuang in Changyi on the Laizhou Bay plain south of Bohai Sea, and analyzed grain size of 86 samples. It shows that, environment-sensitive size fractions of this section respectively are 70.8-79.4 mu m, by analyzing grain-size class vs. standard deviation values method. Changes of percentage of the different size fraction have certain relevance. The section of the lower four layers of loess-paleosol recorded the variations of paleo-environmental evolution and sea level changes over the last glacial stage.
