摘　　要：根据群落调查和统计分析结果,并参考《中国植被》分类原则,将岩下大鲵自然保护区植被分为针叶林、阔叶林、针阔混交林、灌木林、竹林、经济林和灌草坡7个主要植被型,并对部分植被型进一步分类。从林冠层、枯落物层、土壤层及岩性几个方面对保护区的不同植被类型涵养水源功能进行评价。In this paper, through community investigation, statistic analysis and referring to classification principle of Chinese Vegetation, the vegetation in Yanxia natural reserve for Megalobatrachus dovidianua of Guiding county, Guizhou province were divided into seven main types, namely coniferous forest, broad leaved forest, coniferous and broad leaved mixed forest, shrubby forest, bamboo forest, economic forest and shrub and herbosa, and further classification for some of them were proposed. Moreover, the water - holding functions of different vegetation types were evaluated according to canopy layer, litter layer, soil layer and lithology.
