八大公山自然保护区绞股蓝伴生群落特征研究

对八大公山国家级自然保护区的绞股蓝伴生群落特征进行了研究.结果表明,异叶榕、尾叶山茶和水马桑等是常见的对绞股蓝具有遮荫作用的乔灌层植物.绞股蓝伴生群落计有47科86属102种维管植物,以蓼科、伞形科、菊科和百合科种类较多,绵毛金腰是伴生群落的优势种,它与冷水花、吉祥草、楼梯草和箬竹等是绞股蓝的重要伴生种.伴生群落的物种多样性指数表明整个环境适于绞股蓝的生长.

Studies on Traits of Concomitant Community of Gynostemma pentaphyllum in Badagongshan National Reserve

The traits of concomitant community of Gynostemma pentaphyllum in Badagongshan national reserve were studied. The results showed that Ficus heteromorpha, Camellia candata and Weigelajaponica var. smica were main trees that shadowed the community. The concomitant community of G.pentaphyllum consisted of 102 species, 86 genera in 47 families of vascular plants, and many species were of Polygonaceae, Umblliferae,Compositae and Liliaceae. Chrysosplenium lanuginosum was the dominant species in concomitant community, and Pilea notata, Reineckia carnea, Elatostema f.involucratum and Indocalamus tessellates, were also an important concomitant species to Gynostemma pentaphyllum. The index of diversity suggested that Badagongshan Mountain national reserve was a suitable habitat for G.pentaphyllum growth.
