摘　　要：提供安徽省鹞落坪国家级自然保护区植被类型的初步概况与与比较分析。在世界植被区划上 ,该区属泛北极植物区 ,中国———日本森林植物亚区的华东区 ,是华中、华西、华北、华南植物区系与华东植物的渗透、过渡和交汇地带 ,故植物物种类丰富复杂。今经实地考察 ,并通过对所得的有关数据资料的整理与统计 ,采用相似性系数分析方法 ,对该保护区植被组成进行了初步的探讨 ,认为 :该区计有野生种子植物 134科 ,5 90属 ,14 2 8种 (含种下等级 ) ;该区森林生态系统结构完整 ,植物群落分为 8个植被型 (亚型 )和 35个群系组。主要有针叶林、针阔叶混交林、竹林、灌丛、草甸等 ,此外还有沼泽和水生植被。The preliminary survey and analysis on the flora of Yaoluoping National Resonrces Reserve were presented.According to world floristic recognization system,This area belongs to extensive northern flora.It showed close phylogenetical relation to the floristic regions of the forest vegetation of Eastern China.It is also in connect with the floristic regions of central,western,southern and eastern China.So it owns very rich and comprehensive flora.Through on-the-spot investigation,data arrangement,resemble coefficient analysis,the major characteristics of flora in this region were summed up as follow: 1 There are wild seed plant 34 families,590 genera,1428 species; 2 The primeval reborn forest ecosystem is integrated,the phytocoenosis is separated into 8 distribution types and 35 composition:conifer forest,broadleaf and conifer mixed forest,bamboo forest,bushes,grassy marshland swamp plants and aquaic plants.
