| 摘 要： | 通过实地调查、样方统计、标本采集等,对荔波小七孔地区岩溶植被的生境条件、区系组成、群落学特征等进行了初步的分析研究。结果表明: 该区植被区系十分丰富,在12km2 的范围内,自然分布的维管束植物高达375种,分别隶属于117科、272属;地理成分也相当复杂,既有世界分布、泛热带分布、热带美洲和热带亚洲间断分布、热带亚洲至热带非洲分布,又有北温带分布、东亚和北美间断分布、西亚至中亚分布和中国特有分布。此外,区内岩溶植被多元顶极演替特征也很明显,常绿阔叶、落叶阔叶与常绿落叶阔叶混交林共存。小七孔的这种植被群落特征主要由其气候、土壤、小生境差异及其相互配置的不同而引起。

| Abstract: | This paper is based upon the on-the-spot investigation, sample statistics and specimen collection. The conditions of the habitat, the composition of the flora, and the characteristics of the vegetation community are analyzed and studied. The result is that the vegetation system in this area is so rich that 375 vascular plants of natural classification are existed within 12 km~2, which belong to 272 genera, 117 families. The geographical composition is quite complex, including species that distributed over the world, disconnectedly distributed in pan-tropical area, in American and Asian tropical areas, in African tropical area, disconnectedly distributed over northern temperate zone, over eastern Asia and northern America, over western Asia to middle Asia and China's special distributing. Moreover, the feature of poly-climax succession of karst vegetation in this area is rather obvious since evergreen broad-leaved forest, deciduous broad-leaved forest, and mixed forests between existing together. The characteristics of the vegetation community in Xiaoqikongis are mainly caused by the climate, the soil, the difference of the habitat and their collocation among each other. |
