【摘要】 本文以东北林业大学帽儿山林场老爷岭生态站14林班天然次生林皆伐迹地上人工更新的黄波罗(Phellodendron amurense Rupr.)、水曲柳(Fraxinus mandshurica Rupr.)为研究对象,在一个地形构成的梯度范围内调查了幼树的逐年生长特征,分析比较了不同立地条件下同一树种的生长及相同立地条件下不同树种的生长情况,研究了黄波罗和水曲柳幼树更新和生长的最佳立地条件;通过气候条件对二个树种幼树高生长影响的调查,分析了地形对生态因子重新分配的作用。更多还原

【Abstract】 The study area is located on the secondary forest regions in Northeast China. The trees of Phellodendron amurense and Fraxinus mandshurica are planted with horizontal belts on a versant in 1984. The annual height growth of saplings is investigated. The characteristics of tree height growth are analyzed along the versant, the variations of tree height growth between the two species are compared on the same site. Through the gradient analysis of tree height growth along the versant, the reallocation effcts of the topography on climatic element are explored.更多还原
