摘要
本文对阔叶红松林红松天然更新固定观察研究结果进行阐述,红松天然更新数量在柞树红松林中最多,椴树红松林中次之,枫桦红松林和云冷杉红松林中最差。四个林型红松天然更新1—5年生的幼苗数量分别为其总更新株数的96％、86％、87％、82％,当年生的幼苗又占绝对优势。鼠类、鸟类,球蚜、立枯病、红松落叶病等这些病虫及动物的危害严重影响着红松天然更新的发生发展。研究成果为红松林恢复提供理论依据。
Natural regeneration of korean pine, is best in Mongolia oak-kor-ean pine forests,is Second rate in Lindens-korean pine forests and worst in Costal birch-korean pine or spruce-fir korean pine forests. In the four forest types mentioned above, 1—5 year old seedlings of korean pine make up 96％, 86％, 87％, 82％ respectively of the total in stem number. One year old seedlings is dominant. The natural regeneration and growth of korean pine is severely influenced by mice, birds, korean pine gall aphid, damping-off and korean pine needle east. The results supply a basis for recover of korean pine forests.
