Abstract: On the basis of summarizing the information of woody vines and the investigation and statistics of the campus and the park in Guangdong province, the woody vines of the geographical elements and its application potential in the garden were analyzed in the article. The results showed that there were 578 species (including subspecies, varieties, cultivars and forms) of liana in Guangdong Province, belonging to 59 families and 161 genera. Among them, the tropical families accounted for 71.12% of the total, genus of tropical accounted for 81.99%, which was indicated that the geographical element of Liana had the characteristics of typical tropic. It was in accordance with the East Asia monsoon climate characteristics of Guangdong. Of the liana, 531 species were Guangdong species, accounting for 91.87% of the total, furthermore, 47 species were alien species, accounting for 8.13% only. However, there just 28 families 46 genera 61species be used in landscapes, including 34 Guangdong species and 27 alien species. It demonstrates that the application of species Guangdong liana resources was not enough and had great potential. Thus, we propose that some good varieties would be promoted and domesticated to improve the diversity of woody vines and landscape diversity.
