摘　　要：采用长白山南部30块天然次生林样地和紫椴解析木数据,利用数量化理论Ⅰ,分别评价了5个立地因子对紫椴树高和直径生长的影响,结果表明,坡向、坡度、A层土壤厚度是影响紫椴生长的主导因子;紫椴在半阴坡和半阳坡的生长好于阴坡和阳坡,在≥26°的陡坡生长好于≤25°的斜坡和缓坡,生长量随A层土壤厚度增加而提高。<Abstrcat> By using data of 30 plots of natural secondary forests in southern Changbai Mountain and stem analysis of Tilia amurensis, and by means of quantized theoryⅠ, effects of 5 site factors on growth of height and DBH of Tilia amurensis were evaluated respectively. The results indicated that: directions, gradient of slope and soil depth of layer A were dominant factors influencing growth of Tilia amurensis; Tilia amurensis grew better in east and west of a slope than in north and south of a slope, and grew better in steep slope ≥26 degree than in inclined and gentle slope ≤25 degree; growth improved along with increase of soil depth of layer A.
