| 摘 要： | 研究了太行山中段王屋山南坡的植被分布及其多样性特征,结果表明,该段山体分布最广的乔木树种是青冈（Cyclobalanopsis glauca）和千金榆（Carpinus cordata）,樱桃忍冬（Sambucus willamsii）、珍珠梅（Sorbaria sorbifolia）、连翘（Forsythia suspensa）3种灌木在海拔1500～1600m处分布较多,分布最广的草本植物是羊胡子草（Carex rigescens）和唐松草（Thalictrum aquilegifolium）.就物种多样性而言,海拔1600m左右的植物总物种数最多,为（18.67±1.53）种;乔灌木层的Shannon-Wiener多样性指数随海拔的升高大致呈“M”型变化,海拔1550m处乔灌木的多样性指数最小,仅为1.42±0.19,而草本多样性指数变化曲线呈单峰型,在海拔1500m左右达到最大值2.16±0.17.

| Abstract: | The characteristics of plant distribution and diversity in the south slope of the middle section of Taihang Mountain were discussed.The results show that Cyclobalanopsis glauca and Carpinus cordata have more frequency than other arbor species.Three shrub species of Sambucus willamsii,Sorbaria sorbifolia,and Forsythia suspense are mainly recorded in the range from 1 500 m to 1 600 m.Furthermore,two herbaceous species of Carex rigescens and Thalictrum aquilegifolium are frequently found along the elevation gr... |
