The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.

摘要运用样方法对贵州省玉舍国家级森林公园稀有保护植物十齿花群落的物种多样性进行了研究，结果表明：玉舍国家级森林公园十齿花群落以蔷薇科、杜鹃花科、壳斗科、桦木科、山茶科、樟科、忍冬科、山茱萸科等为优势科；10个样地中有8个样地以十齿花种群占绝对优势，其平均重要值高达135.69，远远高于其它种群；十齿花群落乔木层物种丰富度为2.847、Simpson指数为0.601、Shannon-Wiener指数为1.523、种间相遇机率为0.601、均匀度指数为0.569，总体上均小于灌木层(分别为：5.580、0.830、2.377、0.829、0.672)，表现为较明显的亚热带常绿落叶阔叶混交林的物种多样性特征。10个样地中，Q1的物种多样性程度最高，Q3次之，Q5和Q6最小，多样性程度最低，10个样地的物种多样性排序为Q1＞Q3＞Q9＞Q7＞Q2＞Q4＞Q10＞Q8＞Q5＞Q6。

The journal established in 1991, focuses on the field of macroecology: the study of broad, consistent patterns in the ecological characteristics of organisms and ecosystems, including studies addressing general ecological hypotheses, exploring and testing using data of broad geographic, taxonomic, or temporal scope; studies documenting ecological and biogeographic patterns, theoretical studies exploring the causes of those patterns, applied studies of impacts of anthropogenic influences, as well as methodological studies of the tools used to study these problems; broad-scale patterns of biodiversity, ecosystem responses to global climate change, historical and evolutionary biogeography, remote sensing of ecosystem properties, species abundance and species range patters, and statistical methodologies.
