摘要
为了弄清南岳自然保护区内藤本植物资源现状,对该区内藤本植物进行了多样性调查研究。结果表明:野生藤本植物共计59科129属282种(含变种),其中蕨类植物有3科5属6种,双子叶植物有50科112属250种,单子叶植物有6科12属26种,裸子植物缺乏。该区地理成分复杂多样,科级地理成分有8个分布型,属级地理成分有12个分布型,种级地理成分有11个分布型,均以热带成分为主,温带成分占有较大比例,说明该区热带成分向温带渗透和过度的性质。藤本植物的生活型,以木质藤本占优势,为60.64%,草质藤本占39.36%,一年生藤本占14.41%。藤本植物的攀援类型分为4型9亚型,以缠绕类为主,占37.94%;其次为吸固类,占23.05%,又可分为不定根类、吸盘类和寄生类3亚型;卷曲类占20.93%,又可分为须卷类、柄卷类和枝卷类3亚型;刺蔓类最少占18.09%,又可分为枝蔓类和钩刺类2亚型。该区藤本植物资源丰富,在垂直绿化与经济开发上具有十分广阔的前景。
The investigation on the vine diversity of Nanyue Nature Reserve of Hunan was presented in this paper.Results show： there are 282 species（including varieties） belonging to 129 genera of 59 families in Nanyue Nature Reserve,of which 6 species belonging to 5 genera of 3 families of ferns,250 species of 112 genera in 50 families of dicotyledons,26 species of 12 genera in 6 families of monocotyledon in this area.However,gymnosperm is absent from this area.The photogeographic elements which can be divided into 8 area-types of family,12 area-types of genera and 11 area-types of species are complex.They are the major tropical,and some temperate one,indicating the transition area of the tropic to the temperate one.Woody vine occupies 60.64% of the plant life forms;nevertheless,herb vine and annual vine take up 39.36% and 14.41%,respectively.Climbing types can be divided into 4 types of 9 subtypes,of which the twining type is the majority and occupies 37.94%.The adhering type occupies 23.05% and can be divided 3 subtypes： the adventitious root adhering,adhesive adhering and paraste.The curling type occupies 20.93% being divided into 3 subtypes： the tendril curling,petiol curling and branch curling.The thorn creepen occupies 18.09% being divided into 2 subtypes of shoot creeper and hook thorn.
