摘　　要：根据文献资料查阅和野外调查,丽水市共有兰科Orchidaceae植物50属98种,属、种数量分别占浙江省兰科植物总属数、总种数的92.59%和81.00%,主要属为兰属Cymbidium(7种)、舌唇兰属Platanthera(7种)、石豆兰属Bulbophyllum(7种),有国家二级重点保护野生植物16种,有极危(CR)物种3种。丽水兰科植物区系的地理成分较为复杂、多样,属级有10个地理成分,以热带成分(2~7)略占优势(56.00%),温带成分(8~15)占44%,表明属级层面热带和温带共同起源;种级地理成分有6个类型,以温带成分占绝对优势(80.61%),并以东亚分布(44.90%)和中国特有分布(34.69%)占优势,表明种级层面以东亚分化和中南半岛分化为主。区系成分比较分析表明,本区与云南、广西和中南半岛兰科植物区系有较密切的联系,具有从热带向亚热带过渡的特点。According to literature review and field survey,there are 50 genera and 98 species of Orchidaceae plants in Lishui City,accounting for 92.59%and 81.00%of the total in Zhejiang Province,respectively.The main genera are Cymbidium(7 species),Platanthera(7 species)and Bulbophyllum(7 species),and 16 species of national second-class key protected wild plants,and 3 species of critically endangered(CR)plants.The geographical components of the Orchidaceae flora in Lishui are complex and diverse.There are 10 geographical elements at the genus level,with tropical elements(2−7)slightly dominant(56.00%)and temperate elements(8−15)accounting for 44%,indicating that the tropical and temperate Common descent at the genus level.There are 6 types of species level geographical elements,with temperate elements accounting for Absolute advantage(80.61%),and East Asian distribution(44.90%)and Chinese endemic distribution(34.69%),indicating that East Asian differentiation and Southeast Asia Mainland differentiation are dominant at the species level.The comparative analysis of floristic elements shows that the region is closely related to the orchid flora of Yunnan,Guangxi and Mainland Southeast Asia,and has the characteristics of transition from tropical to subtropical.
