摘要: 壶瓶山国家级自然保护区生物多样性丰富,区系组成复杂,受人类活动干扰明显,植被次生性强,建群种优势度不高,其孢粉组合特征复杂多样。本文研究了壶瓶山34个样点表土孢粉组合特征及其与植被的关系。结果表明: 孢粉组合中木本植物含量(84.4%)占绝对优势,木本植物花粉与非木本植物花粉比值约为5.4,孢粉浓度为149157粒·g-1。常绿阔叶林花粉组合难以反映母体植被植物组成特征;落叶阔叶林花粉组合只能部分反映母体植被特征;常绿落叶阔叶混交林、山顶灌丛草甸和玉米地花粉组合可以较好地反映母体植被植物组成规律,群落优势种和建群种在花粉组合中能够得到较好的体现。栲属/柯属、水青冈属、漆树属、鹅耳枥属/榛属、杜鹃花科和山矾属花粉具低代表性,松属、桦木属和青冈属花粉具超代表性。花粉百分含量的聚类分析和降趋势对应分析,能较好地区分山顶灌丛草甸、常绿阔叶林和落叶阔叶林,但常绿落叶阔叶混交林与常绿阔叶林和落叶阔叶林均存在部分重叠现象。孢粉组合对母体植被的指示性差异明显,这主要受孢粉代表性、植被斑块化特征、地形地势、地方小气候和人类活动等多重因素影响。

Abstract: Hupingshan National Nature Reserve, located in Hunan Province, South Central China, is characterized by rich biodiversity, complex floral composition, pronounced human perturbation, dominant secondary vegetation, low dominance of constructive species, and complex and diverse pollen assemblage characteristics. We explored the relationship between surface pollen assemblages and vegetation characteristics using 34 samples. The results showed that arboreal pollen accounted for 84.4% of the total. The AP/NAP (AP: arboreal pollen, NAP: nonarboreal pollen) ratio was roughly 5.4. The pollen concentration was 149157 grains·g-1. Evergreen broadleaved pollen assemblages did not reflect the local vegetational community. Pollen assemblages of deciduous broadleaf forest were partly consistent with plant community composition. Deciduous-evergreen broadleaf mixed forest, shrub-meadow and corn field pollen assemblages corresponded well with their local vegetational community. Local dominant species and constructive species abundances were well represented in pollen assemblages. Castanopsis/Lithocarpus, Fagus, Toxicodendron, Carpinus/Corylus, Ericaceae, and Symplocos were under-represented, whereas Pinus, Betula and Cyclobalanopsis were over-represented pollen taxa. Based on cluster analysis and detrended correspondence analysis (DCA), the shrub-meadow, evergreen broadleaf forest and deciduous broadleaf forest could be well distinguished by pollen spectra, except deciduous-evergreen broadleaf mixed forest, or evergreen broadleaved forest and deciduous broadleaved forest. The significant discrepancy in consistency between pollen assemblages and vegetation community was chiefly impacted by pollen representativeness, vegetation patchy characteristics, topography, local climate, and human activities.
