| 摘 要： | 通过对南平4个不同植被类型的表土样品的孢粉分析,得出了该区的表土孢粉组合特征.结果显示:研究区内的表土孢粉组合中草本植物占据优势,乔木主要为马尾松,灌木的种类和数量都很少,显示该区植被退化严重,表现出石漠化地区孢粉组合的显著特点.研究区内不同植被类型的表土孢粉组合差别明显,但与其相应的实际植被情况大致相同,能够较好地反映出石漠化地区现代植被的基本状况.表土孢粉组合中有很多喜钙性、旱生性、石生性植物,对生态恢复和重建有很好的指示意义,为该区恢复和重建自然生态环境提供参考性依据.

| Abstract: | By analysis of the surface spore-pollen samples of five different types of vegetation of Nanping,the surface soil spore-pollen assemblage characteristics in the area were obtained.The results showed that the spore-pollen assemblage in study area was dominated by herbaceous plants.Trees are mainly of Pinus massoniana Lamb,and the types and quantities of shrubs are very small,indicating a serious degradation of local vegetation.The desertification areas show a distinctive feature of spore-pollen assemblage.Sp... |
