| 摘 要： | 分别采用Simpson指数、Shannon-wiener指数Pielou均匀度指数和种间相遇机率等方法,分析了不同林龄杉木人工林的物种多样性。结果表明,不同林龄杉木人工林的植物种类及物种多样性存在明显差异。中龄林和成熟林植物种类较丰富,乔木层和灌木层物种多样性较高,而幼龄林草木层物种多样性较高。

| Abstract: | The species diversity of Chinese fir plantation with different forest age was analyzed with the methods of Simpson index,Shannon-wiener index,Pielou evenness index and interspecific encounter probability etc. The results showed that the plant species and species diversity in Chinese fir plantation with different forest age was obviously different. The plant species in middle-age forest and mature forest was abundant and the species diversity in tree layer and shrub layer was higher. While the species divers... |
