以样方调查数据为基础,采用物种丰富度指数、均匀度指数、多样性指数对福建省大田县梅林国有林场马尾松杉木混交人工林林下种植草珊瑚对林下植物多样性的影响进行研究,并分析林下种植草珊瑚样地和未种植草珊瑚(对照)样地以及草珊瑚不同种植年限样地之间各种指数的差异程度。结果表明:①林下种植草珊瑚(栽植1 a、2 a)对灌木层产生了显著的影响,降低了物种多样性;②林下种植草珊瑚使草本层的丰富度指数和Shannon-Wiener 指数显著下降,Pielou指数和Simpson指数显著上升;③草珊瑚种植1 a与种植2 a后林地物种多样性指数除了丰富度指数有显著差异外,其他指数差异均不显著;④开展林下种植草珊瑚,要兼顾经济效益和生态效益。
以樣方調查數據為基礎,採用物種豐富度指數、均勻度指數、多樣性指數對福建省大田縣梅林國有林場馬尾鬆杉木混交人工林林下種植草珊瑚對林下植物多樣性的影響進行研究,併分析林下種植草珊瑚樣地和未種植草珊瑚(對照)樣地以及草珊瑚不同種植年限樣地之間各種指數的差異程度。結果錶明:①林下種植草珊瑚(栽植1 a、2 a)對灌木層產生瞭顯著的影響,降低瞭物種多樣性;②林下種植草珊瑚使草本層的豐富度指數和Shannon-Wiener 指數顯著下降,Pielou指數和Simpson指數顯著上升;③草珊瑚種植1 a與種植2 a後林地物種多樣性指數除瞭豐富度指數有顯著差異外,其他指數差異均不顯著;④開展林下種植草珊瑚,要兼顧經濟效益和生態效益。

Based on the datasets from sampling plots ,and by using species richness index ,evenness index ,and diversity index ,this paper studied the effects of planting Sarcandra glabra on the understory plant species diversity in Masson Pine and fir mixed Planta-tion of state-owned forest Meilin in Datian County ,Fujian Province ,and analyzed the differences in the test indices among different planting practice sites.The results showed that:①The planting of Sarcandra glabra decreased the species diversity of shrub layer sig-nificantly.②Planting Sarcandra glabra decreased the species richness and Shannon-Wiener indices , but increased the Pielou and Simpson indices of herb layer significantly.③All the test indices of herb layer had no significant differences between the different Planting years of Sarcandra glabra except the richness index.④To take into account the economic and ecological benefits when con-ducting planting Sarcandra glabra.
