摘　　要：本文初步探讨了贵州喀斯特区不同藤本植物的截留能力变化特征。结果发现:对于喀斯特区不同藤本植物而言,茎截留率表现为葛藤>金银花>西番莲>任豆,叶片截留率表现为西番莲>葛藤>任豆>金银花,且叶片的截留能力比茎的截留能力强;在单位叶面积截留率中,任豆的截留能力最强。说明任豆可以作为贵州喀斯特区一种良好的固土护坡藤本植物。This paper made a preliminary analysis on change characteristics of interception capacity of different vine plants in Guizhou karst area.The results showed that for different vine plants in karst area,the stem interception rate was kudzu>honeysuckle>passionflower>zenia,blade interception rate was passionflower>kudzu>zenia>honeysuckle,and blade interception capacity was stronger than that of the stem.From the perspective of interception rate per unit leaf area,zenia had the strongest interception capacity.It showed that the zenia could be used as a good vine plant for soil stabilization and slope protection in Guizhou karst area.
