The result of factor analysis can provide the changes of relative precipitation and temperature variations. In trace elements, Cu, As, Zn, Pb and Ni were apparently enrichmented in soil layers and are sensitive to climatic changes. Carbon isotope is more sensitive to climatic changes than that of oxygen isotope in loess stratigraphy. The heavy mineral are varified in the loess stratigraphy, but their content differences between loess and palaeosol is little. Though the palynologic analyses results reveal that pollens and spores are fewer in the loess stratigraphy, they differ greatly in loess layer and palaeosol layer not only in species but also in types, i. e., the pollens and spores indicating warm and moist climate, such as Lles, Podocarpus, Polopydium, Pteris grerilliana Wall, Pterocarya and Juglans appear in palaeosol layers, while those indicating cold and dry climate such as Ephedra, Artemisia, Chinopodiaceae, Picea and Abies exist mainly in loess layers. The pollen content of broad-leaved tree mainly consisting of Pterocarya is up to 60% in palaeosol 〓, while the content of Ephedra is more than 50% in 〓 loess layer, showing that the environment differed greatly when 〓 and 〓 were formed.
