Abstract: A systematic and effective method has been worked out for pollen-spore analysis in loess. In this method, both chemical and physical treatment was appropriately employed according to the loess characteristics, such as its chemical composition, etc. So the pollenspores could be sorted out of loess to the highest limit. Abundnat pollen-spores have been obtained in more than 90 samples taken from seven sections in Shaanxi and Gansu provinces where the loess is best developed. Observed 1 to 3 pieces of glasses, the total pollen-spores could be sorted out more than 204 to 594, and 39 to 551 thousand particles of 250 g of loess sample.

Key words: Loess, Pollen-spore, Analysis method
