| 摘 要： | 本文在对北疆20块表土样品分析的基础上,将灰色系统理论的概念应用于表土孢粉组合研究,用关联度分析权重指数和法探讨了北疆部分植被类型生境与孢粉组合之间的关系,并归纳出环境评价等级指数和与植被带的对应关系,经初步检验,对应关系与实际状况基本相符,此方法将有利于运用孢粉分析手段较迅速而准确地解决新疆第四纪古生态环境及其演化问题。

| Abstract: | Based on the sporo-pollen analysis of the surface samples from northern Xinjiang,the Grey Sys-
tem,a new mathematical theory,was applied to the research on the sporo-pollen assemblages in the
surface samples.The relationship between the sporo-pollen assemblages and the surrounding vegetation
was approached by the method of weight index analysis from correlation degree.The corresponding
relationship between the sum of ecotope grades index and vegetation zones was induced and rested.
This method would henefit the research on the paleo-ecological environment and its evoiution with the
aid of sporo-pollen analysis more promptly and precisely. |
