Abstract:In order to understand the current status of vines in Tongbiguan Nature Reserve, the diversity and composition of vines were studied by field survey. The results showed that there are 676 vine species belonging to 65 families and 209 genera in Tongbiguan Nature Reserve. Dicotyledonous vines donimate in the species composition, with 597 species belonging to 192 genera and 56 families. According to life-form, phanerophyte vines are predominant, accounting for 81.51% of the total. Twining vines are the majority and account for 53.99% of the total. The concept of leaning vines is proposed. High rainfall, undulating altitudes, diverse habitat types, and highly diverse primary broadleaved forests are significant of the enormous abundance of vines in this region.
