摘要
对武夷山自然保护区丝栗栲天然林群落进行物种多样性的研究结果表明,该群落的物种多样性和均匀度较高,群落的Shannon-Wiener多样性指数为3.4387,均匀度指数为0.6863;其乔木层、灌木层和藤本层的物种多样性较高,均匀度也较高,它们的Shannon-Wiener多样性指数分别为2.7751、3.7983和2.3357,均匀度指数分别为0.8241、0.8619和0.7169。由于草本层的优势种在个体数上的优势导致草本层的物种多样性和均匀度降低,其Shannon-Wiener多样性指数为0.6733,均匀度指数为0.2710。
The species diversity in Castanopsis fargesii natural forest community in Wuyishan Mountains was studied, the results showed that in this community, the Shannon-Wiener index and the Plelou evenness were high,amounting to 3.4387, and 0.6863 respectively; the shrub layer,larbor layer and liana layer′s Shannon- Wiener index and the Plelou evenness were high,too,amounting to 3.7983,2.7751, 2.3357,and 0.8619, 0.8241, 0.7169 respectively. Owing to the superior number of the individuals of some dominant species, the diversity and evenness of the herbaceous layer were low, amounting to 0.673 3 and 0.2710 respectively.
