摘要: 在对遥感数据进行景观分类和对环境因子进行空间表达基础上,在地理信息系统的支持下,确定长白山自然保护区森林景观分布的环境(包括年均温、年降水量、坡度和坡向)范围.结果表明,从苔原、岳桦、云冷杉到阔叶红松林,最适海拔高度范围依次为1780~2212、1705~1956、1042~1625、823~1184m;最适温度范围分别为-4.75~-2.40℃、-3.42~-2.07℃、-1.49~1.39℃、0.71~2.37℃;最适降水范围分别为1034~1110、1014~1060、883~1017、824~925mm;长白山自然保护区的森林景观主要分布在平、缓坡地上,并与坡向关系密切,苔原在各个坡向上均有分布,且在各个坡向上分布面积的变化不大;岳桦、云冷杉林、阔叶红松林、山杨白桦林主要呈现北、西北向分布,其次为东北、西向分布;落叶松林主要为东北向分布,其次为东和北向分布;疏林主要为西向分布,其次为西南、西北和南向分布;风倒区主要为西、西南、西北向分布.

Abstract: 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℃,- 3.42 ~-2.07℃, -1.49~1.39℃, and 0.71~2.37℃, and the optimum ranges of annual precipitation were 1034~1110mm, 1014~1060mm, 883~1017mm, and 824~925mm, 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.
