摘要:
 通过实地样方调查和数据分析,对甘肃插岗梁自然保护区大果青杄群落物种多样性进行研究。结果表明,甘肃插岗梁自然保护区大果青杄群落适宜生存的海拔是1 800~1 900 m,其中乔木层的生态优势度最高,而均匀度指数非常低,说明了乔木层物种单一,大果青杄在乔木层占有绝对优势。各层物种多样性大小依次为草本层>灌木层>乔木层。
Abstract:
 By the methods of field survey and data analysis,an investigation was conducted on the species diversity in the community of Picea neoveitchii.The results showed that the altitude of the community was within the range of 1 800-1 900 m.The diversity of species in the community was in the order of herb layer>shrub layer>tree layer,and the sequence of ecological dominance was opposite.The evenness index of tree layer was also very low,which indicated that P.neoveitchii was dominant in tree layer and whole communit.
