摘要：幕阜山地处中亚热带一北亚热带过渡地带，物种资源丰富。通过对其典型样地的调查，分别采用Shannon-Wiener指数、Simpson指数和Pielou均匀度指数作为测度指标，研究了幕阜山地区森林群落结构及其物种多样性特征。结果表明，该地区主要有21个森林群落类型。其中常绿阔叶林中，物种丰富度指数与多样性指数在群落梯度上的总体趋势均为灌木层相对高于乔木层，乔木层相对高于草本层；在落叶阔叶林中，其丰富度指数的趋势为灌木层〉草本层和乔木层，而在草本层与乔木层间是波动的，多样性指数的趋势为灌木层〉草本层〉乔木层；在针叶林中，物种丰富度、多样性指数表现的总趋势基本一致，即灌木层的丰富度相对较高，其次为草本层，乔木层的相对较小。在其他群落类型中，多样性指数、均匀度指数在乔木层、灌木层和草本层则表现出多样化的趋势；另外，从总体上看，各种指数在海拔梯度上并未表现出明显的规律性。
Located in transitional zone between central subtropical and north subtropical climatic area, Mufu Mountain is rich in species resources. Based on typical sample plot survey, the community structure and species diversity of the forest community were determined with Shannon-Wiener diversity index, Simpson index and Pielou evenness index. The results showed that there are 21 forest community types. In the evergreen broadleaf forest, the shrub layer had the highest richness index and species diversity index, followed by the tree layer and the herb layer had the lowest. In the deciduous broadleaf forest, the shrub layer had the highest richness index, but in the herb layer and the tree layer, the trend fluctuates; and the shrub layer had the highest species diversity index, followed by the herb layer and the tree layer had the lowest. In the coniferous forest, the shrub layer had the highest richness index and species diversity index, followed by the herb layer and the tree layer had the lowest. In other communities, the trend of all indices along the community shows a trend of diversification. Generally speaking, all the indices along an elevation gradient didn＇t show an obvious consistent trend.
