| 摘 要： | 用3个丰富度指数、2个多样性指数和3个均匀度指数对威海市区11个黑松林群落多样性进行研究,并用相关分析研究了这些指数间的关系,结果表明:(1)黑松混交林群落的丰富度和多样性均高于黑松纯林群落,但均匀度却无此规律;(2)生境最优的黑松+刺槐+麻栎林(位于仙姑顶的样地11)在11个样地中的物种多样性表现最好,丰富度、多样性和均匀度都最大.而生境最差的位于火炬大厦的黑松纯林(样地2)群落的丰富度和多样性指数都最小;(3)除样地2外,其余样地群落的草本层丰富度和多样性都最大,灌木层次之,乔木层最小,均匀度无此规律;(4)3个丰富度指数之间、2个多样性指数之间以及两个Pielou均匀度指数之间存在极显著的相关性,但Alatalo均匀度指数和其它7个指数之间相关性都不显著,同时对8个物种多样性指数进行比较后发现丰富度指数中Patrick指数(S)最优,而多样性指数中Shannon-Wiener(H)最优,均匀度指数中以H为基础计算出的Pielou(JH)指数最优.

| Abstract: | Three richness indices,two species diversity indices and three evenness indices were used to analyze eleven Pinus thunbergii forests at Weihai city. In addition,relationships among these indices were studied by correlation analysis. The results indicated that:(1) species diversity indices and richness indices of mixed forests were higher than those of pure forests,while there was no this trend for the evenness indices;(2) these indices of Pinus thunbergli+Robinia pseucdoacacia+Quercus acutissima forest,loca... |
