摘要
根据黄土的化学成分等特点，采取相应的化学及物理相结合的处理方法，把孢粉离析出来。在黄土最为发育的陕西、甘肃７ 个黄土剖面计９０ 多个样品中均获得丰富的孢粉，观察１—３ 张玻片，孢粉总数可达２０４—５９４ 粒以上，２５０ ｇ 的土样可获得３．９—５５．１
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 pollen spores 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.
