%X With the dataset in the investigated field, we studied the species diversity of <em>Carpinus cordata</em> communities in Lishan Nature Reserve, Shanxi Province by using Patric index(<em>R</em><sub>0</sub>), Simpson index(<em>&lambda;</em>), Shannon-Wiener index(<em>H</em>'), Pielou index(<em>E</em><sub>1</sub>) and Alatalo index(<em>E</em><sub>5</sub>). The change trends of <em>R</em><sub>0</sub>, <em>H</em>', <em>E</em><sub>1</sub> and <em>E</em><sub>2</sub> was almost similarity, and the change trends of <em>&lambda;</em> with <em>H</em>' was positive. Overall, the rank of species diversity indices of <em>C.cordata</em> communities was Ass. Ⅰ <em>Carpinus cordata-Lindera glauca-Phlomis umbrosa</em> &gt; Ass. Ⅲ <em>Carpinus cordata-Forsythia suspense-Phlomis umbrosa</em> &gt; Ass. Ⅳ <em>Carpinus cordata-Spiraea pubescens+Forsythia suspense-Smilacina japonica</em> &gt; Ass. Ⅶ <em>Carpinus cordata-Sambucus williamsii-Thalictrum baicalense+Epimedium brevicornu</em> &gt; Ass. Ⅱ <em>Carpinus cordata-Deutzia parviflora-Phlomis umbrosa</em> &gt; Ass. Ⅵ <em>Carpinus cordata-Deutzia parviflora-Osmorhiza aristata</em> &gt; Ass. Ⅴ <em>Carpinus cordata-Deutzia parviflora-Smilacina japonica</em>. The diversity indices between the tree layer and shrub layer was negative correlation(<em>P</em>&lt;0.05),and the diversity indices between the tree layer and herb layer was negative correlation(<em>P</em>&lt;0.05) also, moreover, the diversity indices between the tree layer and herb layer was negative correlation(<em>P</em>&gt;0.05). The differences among those associations of the <em>C.cordata</em> communities was not significant(<em>P</em>&gt;0.05).
