摘　　要：在研究济南市南部山区森林水源涵养评价的基础上，利用GIS建立了济南市南部山区森林水源涵养数据库，并进行相关分析．结果表明：在各类森林类型中，水源涵养能力由低到高的林木类型依次是有林地、灌木林地、疏林地、经济林地；森林水源涵养密度等级最重要的地区主要分布在历城区、章丘区和长清区．本研究为济南南部山区森林水源涌养功能的生物与经济价值评估提供了科学的理论依据，对济南市的生态环境建设有着积极的指导作用．On the basis of studying and evaluating forests＇ water - source conservation in the southern mountain of Jinan,we can use software related with GIS to build the database of forests＇ water - source conservation on southern mountain of Jinan. From the results we can see that the capacity of water - source conservation from the lowest to the highest is Forest Land, Shrub land, Sparse -woods and Economic woodland in the various types of forests. In different districts of the southern mountains in Jinan, the most important density level of forests＇ water conservation areas are mainly distributed in Licheng District, Zhangqiu area and Changqing District. The study supplies scientific and theoretical basis for the biological and economic evaluation of forests＇ water - source conservation on the southern mountain of Jinan. Besides, it plays a positive role in guiding the construction of the ecological environment of Jinan.
