Abstract:

The complexity of natural conditions leads to the complexity of vegetation types of Taiwan of China, which has both tropical and cold-temperate vegetation types, and could be depicted as the vegetation miniature of China or even for the world. The physiognomic-floristic principle was adopted for the vegetation classification of Taiwan. The units of rank from top to bottom are: class of vegetation-type, order of vegetation-type, vegetation-type, alliance group, alliance and association. The high-rank units (class , order and vegetation-type) are classified by ecological physiognomy, while the median and lower units by the species composition of community. At the same time the role of dominant species and character species will also be considered. The dominant species are the major factor concerned with the median ranks (alliance group, and alliance) because they are the chief components of community, addition-ally their remarkable appearance is easy to identify; the character species (or diagnostic species) are for relatively low ranks (association) because they will clearly show the interspecies relation-ship and the characteristics of community. According to this principle, vegetation of Taiwan is classified into five classes of vegetation-types (forests, thickets, herbaceous vegetation, rock fields vegetation, swamps and aquatic vegetation) , 29 orders of vegetation-types (cold-temperate needle-leaved forests, cool-temperate needle-leaved forests, warm-temperate needle-leaved forests, warm needle-leaved forests, deciduous broad-leaved forests, mixed evergreen and deciduous broad-leaved forests, evergreen mossy forests, evergreen sclerophyllous forests, evergreen broad-leaved forests, tropical rain forests, tropical monsoon forests, coastal forests, warm bamboo forests, evergreen needle-leaved thickets, sclerophyllous thickets, deciduous broad-leaved thickets, evergreen broad-leaved thickets, xerothermic thorn-succulent thickets, bamboo thickets, meadows, sparse shrub grasslands, savannahic grasslands, sparse scree communities, chasmophytic vegetation, woody swamps, herbaceous swamps, moss bogs, fresh water aquatic vegetation, salt water aquatic vegetation) and 53 vegetation-types. The main alliances of each vegetation-type are described.

摘要： 的自然条件导致面积仅为36000多平办公里的台湾兼有热带和寒温带的群落类型，堪称中国乃至世界植被之缩影。它的植被分类也是对中国乃至世界植被分类的补充。台湾植被分类采用的是外貌-区系原则，分类单位和系统自上而下是：植被型纲、植被型目、植被型、群团组、群团和群丛。高级单位(植被型纲、植被型目和植被型)以群落的生态外貌为依据；中、低级单位主要依据种类组成，兼顾优势种和标志种的指示意义。在中级单位中(群团组、群团)，重视优势种的作用，在低级单位中(群丛)更重视特征种(或标志种)的意义。按此原则将台湾植被划分为5个植被型纲(森林、灌丛、草本植被、岩原植被、沼泽和水生植被)，29个植被型目(寒温性针叶林，凉温性针叶林，暖温性针叶林，暖性针叶林、落叶阔叶林、常绿阔叶落叶阔叶混交林、常绿苔藓林、常绿硬叶林、常绿阔叶林、热带雨林、热带季雨林海岸林、暖性竹林、常绿针叶灌丛、革叶灌从、落叶阔叶灌丛、常绿阔叶灌丛、刺肉灌从、竹灌丛、草甸、疏灌草地、干热旱生草地、岩屑堆稀疏群落、石隙植被、木本沼泽、草本沼洋、藓类沼泽、淡水水生植被和成水水生植被)，53个植被型。列举了各个植被型中的重要群团。
