摘 要: 研究了林分各因子对植被的影响,同时还研究了单株树木对植被的影响。从单株方面考察,植被物量(草本)主要分布在样木的中心,0~10D范围内占66.16%,双子叶草本与灌木主要分布在样木中心的外围,生物量和生物种群结构变化拐点在12~15D上。雷林1号品系的林分植被分布丰富,林分土壤类型中对灌木的多样性影响大。 To discuss the effects of stand factors on the distribution pattern of the vegetation in the eucalyptus stand. Examining on the trees, the vegetable biomass mainly distributes in 0~10D from the sample tree about 66.16%. Bifoliate herbaceous and brush distributes outside of the sample tree center, their transformation point of inflection is in 12D~15D. There are more vegetables in Leilin-1# than in other stands. Forest soil types affect sharply on brush diversity.
