摘要
以野外调查的数据和植物群落TWINSPAN分类结果为基础,应用丰富度指数、多样性指数和均匀度指数等物种多样性指数对山西云顶山自然保护区植物群落的物种多样性进行了研究。结果表明:(1)其植物群落13个群丛R0、H′、E_1和E_5的变化趋势基本一致,物种多样性指数综合排序为:群丛Ⅱ>群丛Ⅴ>群丛Ⅸ>群丛Ⅹ>群丛Ⅳ>群丛Ⅵ>群丛Ⅷ>群丛Ⅺ>群丛Ⅰ>群丛Ⅲ>群丛ⅩⅢ>群丛Ⅶ>群丛Ⅻ。(2)森林群落中白杄+华北落叶松–土庄绣线菊+金银忍冬–披针叶苔草+小红菊群丛多样性指数最高,华北落叶松+白桦–金银忍冬–披针叶苔草群丛多样性指数最低;灌丛群落中美蔷薇+刺梨–野青茅+东方草莓群丛多样性指数最高,沙棘+黄刺玫–山蒿+水杨梅群丛多样性指数最低;草本植物群落嵩草+平车前群丛多样性指数比委陵菜+早熟禾群丛高。(3)不同群落类型间的物种多样性指数差异显著(P <0.05),其中森林群落最高,表明群落结构越复杂,物种多样性指数越高。
Based on the dataset from the investigated field and the result of the plant communities classification by TWINSPAN,the species diversity of the plant communities in Yundingshan nature reserve,Shanxi was studied by using species diversity indices,including species abundant index,diversity indices and evenness indies.The results indicated that:(1)Plant communities in the 13 cluster R0,H′,E1,E5 is basically the same trend.The species diversity index of comprehensive ranking:cluster II>clusterⅤ>clusterⅨ>clusterⅩ>clusterⅣ>clusterⅥ>clusterⅧ>clusterⅪ>clusterⅠ>clusterⅢ>clusterⅩⅢ>clusterⅦ>clusterⅫ.(2)the diversity indices of Ass.Ⅱwas the highest and that of Ass.Ⅰwas the least among the forest communities;that of Ass.Ⅸwas the highest and that ofⅩⅢwas the least among the shrub communities;that of Ass.Ⅺwas more than that of Ass.Ⅻamong the herb communities.(3)there were difference significantly among the diversity indices in the community types(P<0.05),among which the diversity indices of the forest communities was the highest,it was suggested that the more complex of the communities,the higher the diversity indices.
