摘要
Pollen analyses were carried out on two loess deposits at Jingbian and Fuxian of the northern Loess Plateau. Grain size of all the samples was measured for stratigraphic correlation between the two sites and for establishment of an orbital time scale. Comparison of the two pollen records shows a north-south climate gradient in both glacial and interglacial periods, i. e. the farther north the colder and drier it becomes, exhibiting a climate pattern similar to the present over the Chinese Loess Plateau. Furthermore, the spatial difference in vegetation composition is more evident in the Holocene Optimum than in the LCM, indicating a steeper climate gradient in warm period than in cold stage.
