摘要:

根据表土花粉分析和植被样方调查,燕山地区各植被带的表土孢粉组合在总体面貌上代表了植被组成,但孢粉组合不等于植被组成,而影响其差异的原因是孢粉保存、孢粉产量、外来孢粉和孢粉鉴定。表土花粉的代表性因种属不同而差异颇大,乔木植物花粉中松(Pinus)、桦(Betula)、胡桃

Abstract:

This study explored the quantitative relationship between pollen in the surface soil and vegetation in the Yanshan area. Data were collected from the region between about 39°00′-40°50′ N and between 117°10′-119°50′ E from 2 082 m elevation in the
