Abstract:
ObjectiveFlora characteristics of vines in Betul alnoides plantation in Daqingshan were studied in order to provide reference for the research of vines in plantation forests. MethodSpecies composition,life forms,climbing styles, geographic distribution of wild vine resources in Daqingshan were studied using the methods of field investigation and liter-ature survey. ResultThere were 30 species of wild vines,belonging to 27 genera in 20 families,most of which were di-cotyledonous plants,accounting for 93.33%of the total. Only one families, one genera and one species of pteridophyta were found in the region,so did gymnosperm. The wild vines were composed mainly of singular families with singular genera. Woody vines were dominant vines in B. alnoides plantation in Daqingshan, making up 70.00% of the total. In terms of life form,phanerophyte vines outnumbered others,accounting for 60.00%of total types, and the proportions of other forms were small. In terms of climbing styles,twining vines were the main type,accounting for 60.00% of the total,followed by curling vines,while the minority styles included hooking and adhering vines. In terms of geographic distribution types ,the vines were mainly tropical plants. ConclusionIn B. alnoides plantations, there are a variety of wild vine species with com-plicated life forms and distribution types. There are great development and utilization value.
