摘　　要：把地理信息系统方法引入林分空间结构研究中 ,对具体指定林分 (硬阔叶林和白桦林 )的林木空间分布进行模拟分析 ,获得它们分化度、混交度、聚集度、不同树种潜在生长空间 ,为研究该区域的森林生态系统修复和空间结构优化决策提供基本信息 ,为森林经营技术的发展提供有效的支持。The GIS approach was used to study the spatial structure of forest stands in this paper. Based on spatial analysis with ArcView for forest stands, the factors of the structure of forest stands were obtained,such as the degree of crop size divergence and the degree of crop cluster and the degree of crop mixed and the potential growth area of trees species in the forest stands. These results will offer the information which is useful for restoring forest ecosystem and optimizing spatial structure of forest stands. It will provide the valuable experience for the development of forest management.
