| 摘 要： | 应用丰富度指数、均匀度指数、多样性指数对山西天龙山植物群落物种多样性进行了研究．结果表明：天龙山植物群落的物种多样性指数与海拔高度有较密切的关系，随着海拔的升高，植物群落的丰富度指数呈上升趋势，均匀度指数呈平缓下降的趋势，多样性指数变化趋势不明显；天龙山植物群落的物种多样性指数和丰富度指数明显受群落类型和群落结构的影响，群落结构越复杂，丰富度指数和物种多样性指数越大，均匀度指数越小．

| Abstract: | Two richness indices,four species diversity indices and five evenness indices were used to analyze the species diversity of the plant communities in Tianlong Mountain,Shanxi.The results shown that the diversity of the plant community in Tianlong Mountain was related to elevation,the richness indices were increased and evenness indices were declined,but the diversity indices were not obvious with the increase of elevation.The diversity indices and richness indices of the plant communities were obviously affected by the type and structure of the community.The more complicated of the structure,the bigger of the diversity indices and richness indices. |
