Jiufeng Forest Park of Beijing was choose as the studied area, and based on the filed data observation and analysis, basic map and information treatment, some factors which effected forest site classification had been studied in quantity and quality to determine the key factors in forestry site classification. By thematic map folding and analysis, Jiufeng Forest Part site classification results and maps came out. The results showed that altitude, slope direction and soil type were the key factors in site classification. Jiufeng Forest Park can be divided into 15 types in site types. By application of "3S" Technology, forest site data both in spatial and attribute can be unified managed. It provided base for sustainable uses of forest resources, forest sustainable development and maintenance the forest ecosystem equilibrium.%选取北京市鹫峰森林公园作为研究区,在对野外调查数据进行整理分析的基础上,对基础图件进行处理及信息提取,对影响森林立地分类的相关因子进行定性和定量分析,确定影响森林立地分类的主导因子;对主导因子专题图进行叠加分析得到鹫峰森林公园立地类型分类结果及相关专题图件.结果表明:以海拔、坡向、土壤类型为立地分类的主导因子,将鹫峰森林公园共划分为15个立地类型.应用"3S"技术进行森林立地分类,实现了森林立地环境因子空间和属性数据的统一管理,为因地制宜、合理开发和持续利用林地资源、维护森林生态系统平衡、发展持续高效林业等提供了基础依据.
