摘　　要：为给太行山低山丘陵区植被建设和生态环境可持续发展提供科学依据,对太行山低山丘陵区经济林和生态林冠层水容量、枯落物水容量、土壤贮水量和土壤入渗能力等涵养水源功能进行了研究。结果表明:乔灌草、灌草相结合的生态林冠层水容量明显大于石榴、枣树,草地最低,乔灌草、灌草结合的林地枯落物贮存量、饱和吸水率和饱和吸水量明显高于石榴和枣树经济林,土壤饱和贮水量和毛管最大贮水量排序为草地>荆条灌丛>薄皮木灌丛>刺槐林>石榴林>枣树林,不同林分的土壤入渗速率依次为薄皮木灌丛>荆条灌丛>枣树林>石榴林。The water conservation function of canopy water volume,litter water volume,soil water storage and soil infiltration capacity of economic forest and ecological forest of the hilly area in Taihang Mountains was studied to provide the scientific basis for vegetation construction and eco-environment sustainable development of the hilly area in Taihang Mountains.The canopy water volume of ecological forest composed with arbors-shrub-grass and shrub-grass is higher than Punica granatum and Ziziphus jujube obviously,and the canopy water volume of grassland is the minimum.The litter storage capacity,water saturated absorption and water absorbing capacity of forests composed with arbors-shrub-grass and shrub-grass are higher than Punica granatum and Ziziphus jujube significantly.The order of soil saturated water storage capacity and maximum soil capillary water capacity is grassland 〉Vitex negundo var.heterophylla 〉Leptodermis oblonga 〉Robinia pseudoacacia〉Punica granatum 〉Ziziphus jujube.The soil infiltration rate of different stands is Leptodermis oblonga〉Vitex negundo var.heterophylla Punica granatum Ziziphus jujube.
