摘　　要：采用森林水文学研究方法,对九仙山小流域不同植物群落的土壤水分贮存与入渗特征进行研究。结果表明:1)森林群落具有显著提高林地土壤孔隙度、土壤贮水量和土壤入渗速率的作用,其中麻栎林要好于侧柏林、刺槐林、杨树林,而枣树林最差;2)有林地的土壤入渗率明显高于荒草坡地,说明不同森林群落具有改善土壤入渗性能的作用。其中侧柏林提高土壤入渗速率的幅度最高,随后是麻栎林、刺槐林、杨树林,最差的是枣树林;3)Horton模型比较适用于模拟研究区的土壤入渗过程,但通用幂函数模型和Philip模型的适用性较差。Use of forest hydrology research methods,to the Jiuxianshan Watershed,forest communities of soil water storage and the Infiltration of the research.The results showed that：1） forest communities Significantly improved in forest soil porosity,soil water storage and soil infiltratio in rate effect.Sawtooth oak forest which is better than oriental arborvitae,black locust,poplar,and the worst is jujube forest;2） the soil infiltration,a woodland soil infiltration rate was significantly higher than shrub-grass,description of forest vegetation to improve the role of soil infiltration.Sawtooth oak forest in improving soil infiltration rate showed the highest,followed is oriental arborvitae,black locust,poplar,and the worst is jujube forest;3） Horton Model is better to the study area for infiltration simulation process,but General power function model and Philip model Poor applicability.
