摘要
在马尾松成林下分别套种拉氏栲、青栲、闽粤栲、格氏栲和苦槠,形成针阔混交异龄林模式,应用物种多样性的多样性指数、均匀度、丰富度指数等指标测定针阔混交异龄林林下物种多样性。分析比较的结果表明,马尾松×苦槠混交异龄林林下物种丰富度指数为最大,马尾松×闽粤栲混交异龄林物种多样性指数及均匀度指数均最大。林下物种多样性研究将为马尾松林下套种阔叶树的混交模式的选择及生物多样性保护提供科学依据。
The analysis and compare results show that the rich degree index of species under Pinus massoniana and Castanopsis sclerophylla mixed unevenaged forest is biggest,the species diversity index and homogeneous degree index of P.massoniana and C.fissa mixed unevenaged forest are all biggest.The diversity research of species under the stands will provide the scientific basis for the mixed pattern selection of interplanting broadleaved trees under the P.massoniana forest,and the biological diversity protection.
