摘要:  金钟山自然保护区计有种子植物101科273属514种,落叶栎林分布面积最广。随海拔升高,植被依次呈现出4个分布带:沟谷落叶阔叶林、沟谷常绿阔叶林、常绿落叶阔叶混交林和落叶阔叶林、山地苔藓矮林和山地常绿阔叶林。该区主要有4个分布区类型:世界分布、热带分布、温带分布和中国特有分布,其中热带分布占总属数的75.21%,表明本保护区的植物分布具有热带性质。其天然植被类型可划分为5个植被型组,7个植被型含暖性针叶林、暖性落叶阔叶林、常绿落叶阔叶混交林、常绿阔叶林、竹林和草丛,2个植被亚型含南亚热带山地常绿阔叶林、山顶阔叶矮林,以及33个群系。

Abstract:  There were 514 species of seed plants belonging to 273 genera and 101 families in Jinzhongshan Nature Reserve. The deciduous oak forest was most widely spread. Four vegetation zones occurred along elevation, viz. deciduous broad-leaved forest, evergreen broad-leaved forest in the valley, mixed evergreendeciduous broad-leaved forest and deciduous broad-leaved forest, mossy dwarf shrub on mountainous tops and evergreen broad-leaved forest in the hilly land. Tropic was dominant accounting for 75.21% of the flora elements including cosmopolitan, temperate and endemic to China. The nature vegetation in Jinzhongshan Nature Reserve was divided into 5 vegetation type groups, 7 vegetation types (warm temperate conifer forest, warm temperate broad-leaved forest, mixed evergreen-deciduous broad-leaved forest, evergreen broad-leaved forest, bamboo forest and grass), 2 vegetation subtypes (South Asia tropical evergreen broad-leaved forest in the hilly land and broadleaved dwarf forest on mountainous tops) and 33 formations.
