武夷山亮叶水青冈林物种多样性研究

STUDY ON THE SPECIES DIVERSITY OF HIGHER PLANTS IN FAGUS LUCIDA COMMUNITY IN WUYISHAN MOUNTAINS

本文为武夷山自然保护区生物多样性GEF项目内容之一,调查了保护区内不同海拔高度的代表性森林生态系统的物种多样性。亮叶水青冈林是山地的代表性森林生态系统之一。应用Shannon—Wiener多样性指数、Pielou均匀度、Simpson指数和PIE对武夷山亮叶水青冈群落高等植物进行了物种多样性研究。结果表明该群落的Shannon—Wiener指数值为1.2973,Pielou均匀度为34.71％,Simpson指数为2.4777,PIE为0.5964,群落的乔木层物种多样性较高,各项多样性指数分别为2.5757,89.11％,12.1179和0.9175,灌木层、草本层的多样性指数值极低。

Shannon—Wiener Diversity index, Pielou evenness, Simpson index, PIE were used to analyse the species diversity of higher plants in Fagus lucida Community in Wuyishan Mountains. The results showed that the former two indices were better, in this community, the Shannon-Wiener index value was 1. 2973, Pielou evenness was 34.71%, the Simpson index was 2. 4777, PIE was 0.5964, in the crown layer, it was 2. 5757, 89.11%, 12. 1179 and 0. 9175 respectively.
