庐山地区野生藤本植物区系与生活型

摘要

通过多年野外调查和查阅相关文献资料,统计整理出庐山野生藤本植物29科72属167种.结果表明:在全部含藤本植物的科属中,含5个种以下的科、属分别占总科数、总属数的44.83％和86.11％；该区藤本植物区系种类组成丰富,地理成分复杂,相互交错,其区系带有热带和温带双重性,其中热带性地理成分为主,有43属,占59.72％;温带性属有25属,占总属数的34.72％,其中以乏热带性地理分布居首位(30.55％),其次为东亚分布(18.06％).生活型以木质藤本属为主,占属总数的50.00％；攀援类型分为4大类,以缠绕类最多,占50.90％,其他依次是卷曲类(28.14％),搭靠类(11.38％),吸固类(9.58％).%Flora and life-form of wild vines resource in Lushan Mountain were studied.Several field investigations were conducted and literature was consulted on wild vines in the Lushan Mountain range with a floristic element analysis being conducted.Results showed that there are 167 species of wild vines,belonging to 72 genera in 29 families.The vine flora was composed mainly of small families with few genera.Families with 1-5 vine species accounted for 44.83 ％ of the total families; whereas genera having 1-5 vine species comprised 86.11％ of the total genera.The vine flora had the features of richness in species,components were complex.The floristic element analysis revealed wild vine flora with tropical (43 of the total genera) features and temperate (25 of the total genera).Among them,Pantropic were dominant,accounted for 30.55％ of all wild vines,followed by East-Asian element (18.06％).Woody vines were also predominant (about 50.00 ％ of the genera).Climbing types of wild vines were divided into 4 types:twining(50.90％),curling(28.14％),hooking (11.38％),and adhering(9.58％).
