湖南省青羊湖国有林场观赏藤本植物多样性研究

Studies on the diversity of ornamental vines in Hunan Qingyanghu State owned Forest Farm

以湖南省青羊湖国有林场的藤本植物为研究对象,通过野外实地调查和文献研究,对该林场藤本植物进行了物种组成、区系成分、攀援类型及观赏类型分析,并利用层次分析法对其开发价值进行评价。结果表明:该区域有藤本植物132种,隶属于38科83属,其中,木质藤本占比较大,有81种,占61.36%;在物种组成上以少种科、属为主;在区系分布上,以热带分布中的泛热带分布最多;在攀援类型上,从多到少依次是:缠绕类、蔓生类、卷须类、吸附类;在观赏类型上,大多具2种及以上的观赏特性;在开发利用上,有68种藤本植物的开发综合评价值在3.0000分以上。本文为青羊湖林场的野生藤本植物资源的保护及可持续利用提供依据,也为美丽乡村建设及周边城市垂直景观构建提供更多素材。

This work sellected the vines of the Hunan Qingyanghu State-owned Forest Farm as the research objects. Through field investigation and literature research, the species composition, flora composition, climbing type, and ornamental types of these vines were analyzed, while the analytic hierarchy process was used to evaluate the values of development and utilization. The results showed that there were 132 species of vines in this area, belonging to 38 families and 83 genera. Woody vines accounted for a relatively large number, with 81 species, accounting for 61.36%. The composition of families and genera was dominated by small families and species in terms of flora distribution. In the tropical distribution, the pan-tropical distribution was the most. The order in terms of climbing types from most to least was winding type, adsorption type, tendril type, and trailing type. In terms of ornamental type, most of them had 2 or more ornamental characteristics. In terms of development and utilization, there were 68 kinds of vines whose comprehensive evaluation value was above 3.0000 points. This research can provide a basis for the protection and sustainable use of wild vine resources in Hunan Qingyanghu State-own Forest Farm, and also provide more materials for the construction of the surrounding urban vertical landscape and the construction of beautiful villages.
