摘要: 对韶关市小坑林场的山杜英Elaeocarpus sylvestris、樟树Cinnamomum camphora、黧蒴Castanopsis fissa、红椎Castanopsis hystrix和火力楠Michelia macclurei纯林的林下植被多样性进行研究。结果表明,山杜英林、樟树林、黧蒴林、红椎林、火力楠林下灌木层分别有12、7、16、10、9种植物,草本层分别有13、11、12、14、20种植物。5种阔叶林样地的物种多样性存在差异, 部分灌木层的物种多样性高于草本层的多样性。山杜英林灌木层的Shannon-Wiener多样性指数及均匀度指数(Jsw和Jsi)分别为2.51、0.70、0.86,高于其他树种的灌木层多样性指数,表明林分种类在林下植物分布格局中起着重要作用,山杜英林有利于林下植物的发育。

Abstract: The diversity of understory plants of Elaeocarpus sylvestris, Cinnamomum camphora, Castanopsis fissa, Castanopsis hystrix and Michelia macclurei stands were studied. The results showed that there were 12 shrub species and 13 herb species in the E. sylvestris forest, 7 shrub species and 11 herb species in the Cin. camphora forest, 16 shrub species and 12 herb species in the Cas. fissa forest, 10 shrub species and 14 herb species in the Cas. hystrix forest, 9 shrub species and 20 herb species in the M. macclurei forest. Shannon Wiener diversity indexes and evenness indices (Jsw and Jsi) of shrub layer under E. sylvestris stand were 2.51, 0.70 and 0.84, respectively, which were significantly higher than those of other stands. This result indicated that stand types played an important role on undergrowth diversity, and the E. sylvestris stand was favorable for undergrowth development.
