中文摘要：
分析和比较了不同造林方式、造林密度、抚育管理等培育措施对桉树人工林林下植物物种多样性的影响。结果表明：不同造林方式对桉树人工林下灌木层和草本层物种丰富度的影响不显著，不同造林密度对桉树人工林林下灌木层物种丰富度的影响显著，对草本层物种丰富度的影响不显著。不同抚育管理对桉树人工林林下灌木层物种丰富度的影响极显著，对草本层物种丰富度的影响不显著。不同造林方式、造林密度、抚育管理对桉树人工林林下灌木层和草本层的Simpson指数、Shannon—Winner指数和Pielou均匀度指数有影响，但差异不显著。
英文摘要：
In this paper, the effects of different cultivation measures （ plantation mode, planting density, forestry management ） on the undergrowth vegetation species diversity of Eucalyptus plantation were analyzed. The results were as follows： The effect of different of plantation modes on the undergrowth shrub layer and herb layer species abundance of Eucalyptus Plantation was not remarkable ; The effect of different planting densities on the undergrowth shrub layer species abundance of Eucalyptus Plantation was remarkable, and on herb layer was not remarkable. The effect of different forestry managements on the undergrowth shrub layer species abundance of Eucalyptus Plantation was extreme remarkable, and on herb layer was not remarkable. The effects of different plantation modes, planting densities and forestry managements on the undergrowth Simpson diversity index, Shannon-Wiener diversity index and Pielou＇s evenness index of Eucalyptus plantation were not remarkable.
