Abstract:

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
