Based on landscape classification of remote sensing data and spatial expression of environmental factors, the abiotic ranges of forest landscape distribution in Changbai Mountain Natural Reserve were determined by using GIS. The results showed that the optimum elevation range of tundra, mountain birch forest, evergreen coniferous forest, and broad-leaved Korean pine forest were 1780-2212 m, 1705-1956 m, 1042-1625 m, and 823-1184 m, respectively. The corresponding optimum annual average temperature ranges were -4.75(-)-2.40 degrees C, -3.42(-)-2.07 degrees C, -1.49-1.39 degrees C, and 0.71-2.37 degrees C, and the optimum ranges of annual precipitation were 1034-1110 mm, 1014-1060 mm, 883-1017 mm, and 824-925 mm, respectively. The forest landscapes in Changbai Mountain Natural Reserve were mainly distributed in flat and gentle areas. This distribution pattern was closely related to aspect. Tundra was almost evenly present in various aspects. In northern and northwestern direction, most forest landscapes were distributed, including mountain birch forest, evergreen coniferous forest, broad-leaved Korean pine forest, aspen and Betula forest. Most larch forest was in favor of northeastern direction with small amount facing eastern and northern way. Sparse forest briefly occupied west aspect with some orienting in southwest, northwest and south, while all wind-thrown areas were facing west, southwest and northwest aspects.
基于遥感数据的景观分类和环境因子的空间表达，利用地理信息系统（GIS）确定了长白山自然保护区森林景观分布的非生物范围。结果表明，苔原、岳桦林、常绿针叶林和阔叶红松林的最佳海拔范围分别为1780 - 2212米、1705 - 1956米、1042 - 1625米和823 - 1184米。相应的最佳年平均温度范围分别为-4.75（-）-2.40℃、-3.42（-）-2.07℃、-1.49 - 1.39℃和0.71 - 2.37℃，年降水量的最佳范围分别为1034 - 1110毫米、1014 - 1060毫米、883 - 1017毫米和824 - 925毫米。长白山自然保护区的森林景观主要分布在平坦和缓坡地区。这种分布格局与坡向密切相关。苔原在各个坡向分布几乎均匀。在北部和西北部方向，分布着大多数森林景观，包括岳桦林、常绿针叶林、阔叶红松林、杨树和桦树林。大多数落叶松林倾向于东北方向，少量朝向东部和北部。稀疏林短暂占据西坡向，部分朝向西南、西北和南部，而所有风倒区均朝向西、西南和西北坡向。
