【摘要】 本文以森林类型为基础,利用数值分析法对东北地区珍贵阔叶树种适地适树进行了研究。白石砬子自然保护区可划分为3个森林类型组和8个森林类型,用逐步回归和立地指数法进行树种立地生产力评价,结果表明A层土厚、坡向、坡度、土壤湿度等是影响人工林生长的主导因子。在阔叶红松混交林,造林树种选择顺序为紫椴、裂叶榆、黄波罗、胡桃楸、水曲柳;而在阔叶杂木林,则是紫椴、胡桃楸、裂叶榆、黄波罗、水曲柳。更多还原

【Abstract】 According to the forest types, sites for plantation of precious deciduous trees are selected by quantitative analysis method. The forest communities in Baishilazi Natural Reserves are classified into three groups and eight types, and their site productivities are evaluated by means of stepwise regression and site index methods. It is indicated that depth of horizon A, soil humidity, slope direction and slope degree are the key factors influencing tree growth. In broadleaved-Korean pine and picea-abics mixed forest, the selected order of planting tree species is Tilia amurensis, Ulmus laciniata, PheIlodendron amurense, Juglans mandshurica, and Fraxinus mandshurica: and that in broadleaves trees mixed forest is Tiliaamurensis, Juglans mandshurica, Ulmus laciniatam, Phellodendron amurense and Fraxinus mandshurica.更多还原
