贵州省黔东南野生藤本植物多样性研究

Study on Wild Vines Diversity in Southeast Guizhou

对黔东南16个县(市)野生藤本植物进行了调查,结果表明:野生藤本植物共计40科88属364种(含变种),双子叶植物有37科84属322种,单子叶植物有3科4属42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,以热带成分为主,温带成分也占有较大比例,具有从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79.95%,草质藤本占20.05%。攀援类型分为4型8亚型,以缠绕类为主,占37.09%。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 wild liane resources in Southeast Guizhou was studied. The results showed that there are 364 species （including varieties ） belonging to 88 genera in 40 families of wild liane in Southeast Guizhou, of which 322 species of 84 genera in 37 families of dicotyledons, 42 species of 4 genera in 3 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 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 79.95% of the plant life forms; nevertheless, herb vine take up 20.05%, respectively, climbine types can be divided into 4 types of 8 subtypes, of which the twining type is the majority and occupies 37.09%. According to economical properties, they may be divided into medicinal plant, ornamental plant, food plant, the industrial plant, green manure forage plant and so on, and have carried out discussion on exploitation of them.
