| 摘 要： | 采用样方调查的方法,分别用重要值、丰富度指数、多样性指数、均匀度指数和相似性指数对通天河国家森林公园山地不同坡向次生林群落各层次物种多样性指数进行了对比分析。结果表明：（1）阴坡各层重要值最高的是华山松、旱柳和银线草,阳坡各层重要值最高的是锐齿栎、忍冬和秦岭蟹甲草。（2）阴坡与阳坡物种多样性具有显著差异。（3）阳坡灌木层的相似系数小于阴坡,阴坡草本层的相似系数小于阳坡。

| Abstract: | By using plot investigation,the species diversities under secondary forest communities were studied on different slope aspects in national forest park of Tongtianhe river by Importance value,Species richness index,Species diversity index,Evenness index and Similarity coefficient index.The results showed that:(1)The highest importance value of tree layer,shrub layer and herb layer shady slope is Pinus armandi,Salix matsudana and Chloranthus japonicus.The highest importance value of tree layer,shrub layer and... |
