摘　　要：在对广东省木质藤本植物资源进行分析的基础上,结合对广州公园和校园的调查、统计,从区系地理学角度分析木质藤本的地理成分以及在园林应用中的潜力。结果显示,广东省木质藤本共有578种(含亚种、变种、栽培种和变型),隶属于59科161属。其中,热带性科占总科数的71.12%,热带性属占总属数的81.99%,表明木质藤本的地理成分具有典型的热带性,这与广东省地处东亚季风气候特点相一致。乡土种531种,占91.87%,外来种47种,仅占8.13%,说明广东省木质藤本乡土植物种质资源非常丰富;但应用于广州园林中的木质藤本仅28科46属61种,其中乡土植物34种,外来植物27种,应用种类较少,园林应用潜力较大。建议在园林建设中通过增加优良种类的应用数量和提高应用频率,以及驯化观赏价值高的乡土种等途径来提高木质藤本的种类多样性和景观多样性。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.
