| 摘 要： | 对不同经营措施桉树林下灌木物种多样性进行研究,结果表明:不同经营措施对桉树林下灌木多样性影响显著。粗放经营桉树林下灌木层物种丰富度、Simpson生物多样性指数和生产力分别是对照黑荆林(CK)的59.1%、79.76%、70.3%;一般经营为CK的90.9%、98.81%、89.2%;中等集约经营为CK的77.3%、85.71%、81.1%;高度集约经营的措施可以有效缓解物种丰富度、Simposon多样性指数和生产力下降,其值分别为CK的90.9%、97.62%和94.6%。采用抚育和施肥结合的高度集约经营措施可以有效提高桉树人工林林下灌木物种多样性。

| Abstract: | The species diversity of shrubs in Eucalyptus spp.plantation under different management practices was studied.The results showed that different management practices had great influence on species diversity of shrubs in Eucalyptus spp.The species richness,Simpson biodiversity index and productivity under extensive management practice was 59.1%,79.76%,70.3% of those of Acacia mearnsii(CK).Those under ordinary management practice were 90.9%,98.81%,89.2% of those of CK.Those under intensive management were 77.3%,85.71%,81.1% of those of CK.And highly intensive management could alleviate the descent of the species richness,Simpson biodiversity indexes and productivity,which were 90.9%,97.62% and 94.6% of those of CK.It means that extensive management practices can improve the species diversity of shrubs. |
