摘　　要：藤本植物是植被的重要组成部分,但由于野外考察中物种及无性系分株鉴定的困难,长期以来在生态学研究中常常被忽视。为揭示中国藤本植物的多样性和特有性,作者研究了其科属组成、区系成分和攀援方式。结果显示:中国藤本植物种类丰富,共计有85科409属3,073种(含变种、亚种),占中国种子植物区系的11.3%;其中草质藤本898种,木质藤本2,175种,分别占中国种子植物区系的3.3%和8.0%。中国藤本植物区系热带成分显著,热带分布科和属分别占总科数或总属数(不含世界广布科属)的87.9%和79.2%;有14个含藤属为中国所特有,但没有特有含藤科。中国藤本植物最主要的攀援方式是缠绕类,占藤本植物总数的56.7%;其次为蔓生类和卷须类,分别占22.1%和17.0%;吸附类藤本种类最少,只占4.2%。Climbing plants（or climbers） are important components of vegetation.They are often overlooked in ecological research due to difficulties in field identification of species or clones.To explore the diversity of climbing plants in China, we report on their taxonomic composition, floristic element types and climbing methods.A total of 3,073 spermatophyte species belonging to 85 families and 409 genera are climbers, accounting for 11.3% of the spermatophyte flora of China, including 898 vines（3.3%） and 2,175 lianas（8.0%）.Tropical floristic elements are common in China, including 87.9% and 79.2% of families and genera containing climber, respectively.Fourteen genera containing climbers are endemic to China.In terms of climbing methods, 56.7% are twining, 22.1% are sprawling, 17.0% are tendrillar and 4.2% are adhesive.
