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.
