| 摘 要： | 黄土－古土壤序列在全球古气候、古环境研究中占有不可替代的重要地位，而其中的孢粉是黄土生态环境演化过程中保存的直接生物学证据，它对建立黄土高原降水或湿度状况的时空变化特征，认为季风变迁的过程，规律以及未来发展趋势等具有重要的意义。随着黄土研究工作的不断深入，作为直接生物学证据的孢粉研究相对薄弱。其中最困扰的因素是从黄土中提取孢粉极其困难，分析技术上始终未能找到一个突破口，因此需要一种分析效果好，快捷

| Abstract: | Loess-paleosol sequence
occupies an important position in the studies of the global paleoclimate and
paleoenvironments. The spore-pollen in loess-paleosol is regarded as the direct biological
evidence for the ecological and environmental changes of loess plateau, which plays an
important role for reconstructing the spatial and temporal charcteristic of precipitation
on the loess plateau, and for understanding the process, regulation, and developmental
trend of monsoon change in the future. With the development of loess study, it is
necessary to find an analysis method of high effect, short process, and lower cost in
order to get a great deal of high precision pollen data. The sieving-analysis method, a
new way of pollen analysis, is designed to fit the study needs of loess pollen. |
