长白山自然保护区位于长白山北坡。从植被的分布,可把长白山北坡的林型划分为:杜鹃岳桦林、红松云冷杉暗针叶林、杜香落叶松林、灌木阔叶红松林和胡枝子长白赤松林五个主要林型。长白山北坡土壤也有明显的垂直带分布。从山顶到山麓,土壤的垂直分布可划分为:山地苔原土、山地生草森林土、山地棕色针叶林土和山地暗棕色森林土四个主要土壤类型。我们在1982年,对山地棕色针叶林土上生长的杜香落叶松林、山地暗棕色森林土上生长的胡枝子长白赤松林和灌木阔叶红松林。三个主要林型下土壤微生物生态分布的季节性动态变化?进行了调查和分析。
Changbai Mountain Nature Reserve is located in the northern slope of Changbai Mountain. According to the distribution of vegetation, the forest types on the northern slope of Changbai Mountain can be divided into five main types of forest: the coniferous forest of Betula ermanii, the coniferous dark coniferous forest of Pinus kumiensis, the larch coniferous forest, the broadleaved Korean pine coniferous shrub and the Lespedeza bicornis plantation type. The soil in the north slope of Changbai Mountain also has obvious vertical distribution. From the summit to the foothills, the vertical distribution of soil can be divided into four major types of soil: mountain tundra soil, mountain grass forest soil, mountain brown coniferous forest soil and mountain dark brown forest soil. In 1982, we planted Daphne alburnii forests on mountain brown coniferous forests, Lespedeza pubescens forest and shrubland broad-leaved Korean pine forests grown on mountain dark brown forest soil. Seasonal dynamics of soil microbial ecological distribution under three main forest types were investigated and analyzed.
