利用郑州市黄河湿地保护区典型草本群落和陕西境内秦岭中段油松—锐齿槲栎混交林群落的调查数据,对2种不同类型群落的8个常用物种多样性指数进行了比较分析。结果表明:8个指数在DCA (除趋势对应分析)二维排序图中的分布明显不同;适用于黄河湿地草本群落的均匀度指数依次为Alatalo、Pielou,多样性指数依次为Simpson、Shannon-Wiener、PIE;适用于秦岭松栎林群落的均匀度指数依次为Pielou、Alatalo,多样性指数依次为PIE、Shannon-Wiener、Simpson;适用于2种类型群落的丰富度指数均依次为Patrick、Menhinick、Margalef;相关系数计算结果进一步证实了DCA排序的可靠性。此外,2种不同类型群落多样性指数的分析结果均表明物种均匀度在影响群落综合多样性水平上的能力高于物种丰富度。
利用鄭州市黃河濕地保護區典型草本群落和陝西境內秦嶺中段油鬆—銳齒槲櫟混交林群落的調查數據,對2種不同類型群落的8箇常用物種多樣性指數進行瞭比較分析。結果錶明:8箇指數在DCA (除趨勢對應分析)二維排序圖中的分佈明顯不同;適用于黃河濕地草本群落的均勻度指數依次為Alatalo、Pielou,多樣性指數依次為Simpson、Shannon-Wiener、PIE;適用于秦嶺鬆櫟林群落的均勻度指數依次為Pielou、Alatalo,多樣性指數依次為PIE、Shannon-Wiener、Simpson;適用于2種類型群落的豐富度指數均依次為Patrick、Menhinick、Margalef;相關繫數計算結果進一步證實瞭DCA排序的可靠性。此外,2種不同類型群落多樣性指數的分析結果均錶明物種均勻度在影響群落綜閤多樣性水平上的能力高于物種豐富度。

Based on the data from typical herb community in the Yellow River Wetland and in Pinus tabuliformis-Quercus aliena var. accuteserrata community in the middle Qiling Mountains, eight common species diversity indices from the two different type communities were compared and analyzed. The results indicate that eight 8 indices’ distributions in detrended correspondence analysis two-dimensional diagram were obviously different;The evenness indices of most suitable to for Yellow River Wetland ranked from big to small as follows:Alatalo, Pielou;the diversity indices for the wetland ranked as:Simpson, PIE, Shannon-Wiener;While the most suitable evenness indices for Qinling Mountains ranked as:Pielou, Alatalo;The diversity indices for Qinling were:PIE, Shannon-Wiener, Simpson. However, the most suitable richness indexes for the both communities were:Patrick, Menhinick, Margalef. The correlation coefifcients conifrmed the reliability of DCA sorting. In addition, the ability of evenness index affecting community biodiversity level was higher than that of richness index.
