摘　　要：应用系统论方法对水源林结构与功能关系进行了阐述,并采用LISREL模型对水源林结构与功能关系进行了定量分析。结果表明,LISREL模型适用于水源林结构与功能关系的分析与研究;林龄、土壤厚度等结构因子对水源林功能具有重要的影响作用。The relationship between structure and function of water conservation forest was elaborated by system theory and analyzed by Liner Structural Relationship MOdel（LISREL）. The results show that LISREL was a suitable method for researching the relationship. Meanwhile, some structural factors of water conservation forest, such as forest age and soil thickness, were the key elements of structure to influence function of water conservation forest. The study was an important signification for reasonable management of water conservation forest.
