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。
Based on the type of forest, this paper studied the suitable tree species suitable for the broad-leaved tree species in Northeast China by means of numerical analysis. The Baishijiazi Nature Reserve can be divided into three forest type groups and eight forest types. The step-by-step regression and site index method are used to evaluate the productivity of the tree species. The results show that soil thickness, aspect, slope, soil moisture, The dominant factor in forest growth. In the broadleaved Korean pine mixed forest, the order of afforestation was Tilia amurensis, Crassulaceae, Huangboluo, Juglans mandshurica and Fraxinus mandshurica; while in broad-leaved mixed woods, Tilia amurensis, Juglans mandshurica, Crassulaceae, Huangpu Luo, ash.
