| 摘 要： | 在三江平原丘陵区佳木斯市孟家岗林场对不同立地条件下长白落叶松人工林生长指标进行标准地调查,建立立地指数导向曲线方程、同形立地指数族、立地指数表和优势木高与立地因子间的数量化模型,在此基础上,评价立地因子对落叶松生长的影响,得出影响落叶松生长的主要立地因子依次为坡向、土壤A层厚、坡度和坡位,适宜落叶松生长的立地是坡度平缓土层深厚的阴坡中下部。

| Abstract: | The growth index of Larix olgensis plantation of various site conditions in Mengjiagang forestry station in hilly areas of Sanjiang plain was investigated with sample plot method.The equation of site index guide curve,the isomorphic site index family,the site index table and the quantification model between superior tree height and site factors were all established.Based on this,the impact of site factors on larch growth was evaluated and it was concluded that the main factors affecting larch growth were slope aspect,soil depth of layer A and the gradient and position of slope in proper order.The most suitable site condition for Larix olgensis growth was the middle-lower position of the shaded gentle gradient with deep soil. |
