摘要
采用踏查和样地调查相结合的方法,对湖南衡山国家级自然保护区藤本植物的基本特征进行了研究。结果表明:(1)本区藤本植物共有39科、78属、142种,分别占该区种子植物科、属、种的27.08%、14.63%和13.52%,且相对集中在某些藤本植物大科中;(2)本区吸固类藤本植物种数为第二、株数第一,缠绕类虽然总种数第一,但其株数位于第二位,且比吸固类少了一半多;(3)本区马尾松成熟林藤本植物多样性指数、种丰富度和多度均最高,阔叶林次之,柳杉林最低;(4)本区阔叶林中藤本植物的平均胸径和平均长度相对于其群落中乔木平均胸径和平均高的比值来说,比马尾松成熟林中的要大;(5)本区阔叶林中的藤本植物以缠绕类为主,吸固类次之,马尾松成熟林中,只有吸固类一种攀援方式,马尾松和杉木混交林中,以吸固类为主,卷曲类次之;(6)样地中被藤本植物感染的乔木树种种数或株数的比率从高至低为马尾松成熟林、阔叶林、柳杉林。
Based on the data of field sampling（exploration,selected sample）,basic characters of vines were studied in Hengshan Mountain National Nature Conservation Zone.The main results show：（1） There were 142 vine species,belonging to 78 genera and 39 families,and the vine diversity was comparably concentrated in some large vine families;（2） Among the vines in this area,adhering type vine species number was second and its individual number was first,and twining type vine species number was first,but its individual number was second and half less than that of adhering type;（3） The highest vine diversity index,species richness and abundance occurred in the Pinus massoniana mature forest,the second in the broadleaved forest,the lowest in the Cryptomeria fortunei forest;（4） The ratio of the average DBH and average length of vine to the average DBH and average height of arbor in the broadleaved forest was higher than that in the Pinus massoniana mature forest;（5） In the broadleaved forest,the species number of twining vine was the most,the adhering type was the second;in the Pinus massoniana mature forest,adhering type was the onlytype;in the Pinus massoniana and Cunninghamia lanceolata mixed forest,the species number of adhering vine was the most,the curling type was the second;（6） The percentages of arbor species and individual number infected by vines from big to small were as followa： Pinus massoniana mature forest,broadleaved forest,Cryptomeria fortunei forest.
