摘要
根据表土孢粉分析和植被样方调查,重庆南平地区5个不同植被类型的表土孢粉分析较好地揭示了石漠化地区孢粉组合特点及其与植被的关系.通过对该区表土孢粉组合特征的对比研究,探讨了影响表土孢粉与现代植被对应关系的主要因素,即外来孢粉、孢粉产量、孢粉保存和孢粉鉴定等.运用LuoPacias孢粉鉴定系统将孢粉鉴定到种,共132种,为在这一地区开展第四纪古植被、古气候和古环境等研究提供参考性依据.
According to spore-pollen analysis of surface soil and Vegetation quadrat investigation,five different vegetation types of surface soil spore-pollen analysis in Chongqing Nanping area revealed spore-pollen assemblage,and the relationship with the vegetation in the desertification areas better.By studying the surface soil spore-pollen assemblage contrastively,we disuss the impact of modern surface spore-pollen and vegetation in the corresponding relationship between the main factors,namely,foreign spore-pollen,spore-pollen production,spore-pollen preservation and spore-pollen identification.Using LuoPacias spore-pollen appraisal system identification of spore-pollen,sum up to 132 species,and the results will provide important and improved information for the study of Quaternary paleovegetation、paleoclimate and palaeoenvironment in the Nanping areas.
