| 摘 要： | 文章分析了原始阔叶红松林和次生杂木林采伐后，人工更新红松、落叶松、天然更新白桦林和撩荒地土壤磷含量的影响。以及落叶松二代林中土壤磷素的变化。其方法是选择不同林龄阶段的落叶松人工林及相邻的红松人工林。天然白桦林和杂木林进行对比研究。研究结果表明，落叶松人工林下土壤磷的含量大于红松人工林和天然白桦林；撩荒的采伐迹地磷的含量显著小于有林地；二代林中土壤磷含量与一代林无显著差异。同时，从速效磷的水平来看，

| Abstract: | The paper analysed P content changement in larch plantation and Korean pine plantation, birch forest which regenerated on cutting area of virgin Korean pine forest and secondary forest The results show as follows: the P content in larch plantation is higher than that in Korean pine plantation and natural birch forest; the P content in forest land is lower than that in non-stocked land; there is no difference of P content in larch plantation between the first rotation and the second rotation; soil acid in larch plantation has no influence on P efficiency |
