摘要: 在野外调查的基础上,应用Patric丰富度指数(R0)、Simpson指数(λ)和Shannon-Wiener多样性指数(H')、Pielou均匀度指数(E1)和Alatalo均匀度指数(E5)等对山西历山千金榆群落物种多样性进行了分析研究。结果表明:(1)千金榆群落R0H'、E1E5等多样性指数变化趋势基本一致,λ与H'等指数变化趋势相反;综合考虑:千金榆群落的物种多样性顺序为群丛Ⅰ(千金榆-山胡椒-糙苏群丛) > 群丛Ⅲ(千金榆-连翘-糙苏群丛) > 群丛Ⅳ(千金榆-土庄绣线菊+连翘-鹿药群丛) > 群丛Ⅶ(千金榆-接骨木-贝加尔唐松草+淫羊藿群丛) > 群丛Ⅱ(千金榆-小花溲疏-糙苏群丛) > 群丛Ⅵ(千金榆-小花溲疏-香根芹群丛) > 群丛Ⅴ(千金榆-小花溲疏-鹿药群丛);(2)乔木层多样性与灌木层多样性、草本层多样性呈负相关(P<0.05),而灌木层多样性与草本层的多样性相关不显著(P>0.05);(3)千金榆各群丛间多样性指数差异不显著。

Abstract: With the dataset in the investigated field, we studied the species diversity of Carpinus cordata communities in Lishan Nature Reserve, Shanxi Province by using Patric index(R0), Simpson index(λ), Shannon-Wiener index(H'), Pielou index(E1) and Alatalo index(E5). The change trends of R0, H', E1 and E2 was almost similarity, and the change trends of λ with H' was positive. Overall, the rank of species diversity indices of C.cordata communities was Ass. Ⅰ Carpinus cordata-Lindera glauca-Phlomis umbrosa > Ass. Ⅲ Carpinus cordata-Forsythia suspense-Phlomis umbrosa > Ass. Ⅳ Carpinus cordata-Spiraea pubescens+Forsythia suspense-Smilacina japonica > Ass. Ⅶ Carpinus cordata-Sambucus williamsii-Thalictrum baicalense+Epimedium brevicornu > Ass. Ⅱ Carpinus cordata-Deutzia parviflora-Phlomis umbrosa > Ass. Ⅵ Carpinus cordata-Deutzia parviflora-Osmorhiza aristata > Ass. Ⅴ Carpinus cordata-Deutzia parviflora-Smilacina japonica. The diversity indices between the tree layer and shrub layer was negative correlation(P<0.05),and the diversity indices between the tree layer and herb layer was negative correlation(P<0.05) also, moreover, the diversity indices between the tree layer and herb layer was negative correlation(P>0.05). The differences among those associations of the C.cordata communities was not significant(P>0.05).
