摘要
辽宁东部山区是辽宁省浑河、太子河等主要河流的发源地和集水区,为辽宁省中南部工农业生产和人民生活用水提供保障。通过对该地区柞树林、杂木林、落叶松林、红松林、油松林等5种主要森林类型的林下枯落物层积累、土壤的物理化学性质等方面进行比较分析,研究结果表明:阔叶林在土壤改良、涵养水源方面较针叶林好,因此,在辽东山区营林时应多营建阔叶林或针阔混交林。
In the paper was conducted comparison and analysis of litters and soil physicochemical characters of 5 forest types of oak,sundry wood,larch ,Korean pine and Chinese pine in the hilly area of the east of Liaoning.The results showed broadleaf forest was better than conifer in soil improvement and water conservation.Therefore it should be more planted broadleaf or mixed forest of conifer with broadleaf.
