用交互信息量分析方法研究了东方红林场地形因子与森林种群及林分类型的相关关系、进而以地形作为分类因子．以地理信息系统作为工具对该区域进行了立地分类。统计了各种立地分类区、立地类型组及亚组的面积。同时、以信息增量为异质性指标，对红松、云杉、冷杉、落叶松、水曲柳在东方红林场的立地适生性进行了空间分析和评价。 The interactive information analysis method was used to study the relationship between the topographical factors and the forest population and forest types in Dongfanghong Forest Farm. Then, the terrain was used as the classification factor. Geographic information systems were used as a tool to classify the area. Statistics of a variety of site classification, site type group and sub-area. At the same time, spatial adaptability of Korean pine, spruce, fir, larch and ash in Dongfanghong Forest Farm was analyzed and evaluated by using information increment as heterogeneity index.
