摘 要 ：通过对新疆天山、阿尔泰山、昆仑山、塔里木盆地、准噶尔盆地不同植被带中所取的 131个表土样中云杉花粉含量进行百分比统计分析 ,从而确定了影响表土中云杉花粉含量的主要因素是距云杉林地距离、海拔高度、气流和水流等。进而指出在荒漠、荒漠草原表土中云杉花粉含量稳定在 5 %以下 ;林带内表土中云杉花粉含量稳定在 30 %以上 ;在森林线以上的亚高山、高山草甸、高山垫状植被以及高山流石滩植被中表土中云杉花粉含量主要受气流的影响 ,而平原河谷林和平原低地草甸表土中的云杉含量则受水流的制约。

Abstract:pollen records from surface soils of the Tianshan Mountains, the Altay Mountains, the Kunlun Mountains, the Tarim Basin and the Jungger Basin in Xinjiang Autonomous Region, northwestern China, were collected from 1986 to 2001. Based on the statistic analysis of content of Picea pollen in these pollen records, we evaluated the major factors such as the distance away from spruce forest, elevation, air current and water course, that influence the content of Picea pollen in surface soils. Relationship between v...
