| 摘 要： | 利用双环法对北京密云山区4种典型林地（刺槐林、侧柏林、针阔混交林和灌木林地）进行原位测试，研究其土壤入渗规律。结果表明:利用Horton公式对土壤入渗过程的拟合精度高于Philip方程；土壤含水量与土壤初渗速率呈极显著的负相关，但与稳渗速率关系并不显著；土壤稳渗速率与土壤密度呈负相关，与土壤有机质含量和孔隙度呈正相关；4 种典型林地土壤稳渗率的顺序为灌木林地(4.93 mm/min) 刺槐林地(4.23 mm/min) 针阔混交林地(4.18 mm/min) 侧柏林地(3.09 mm/min)。

| Abstract: | Soil infiltration characteristics in mountainous areas of Miyun,Beijing were studied with double-ring method based on field investigation in four typical plantations(Robinia pseudoacacia,Platycladus orientalis,conifer-broadleaf mixture,and shrubs).Results showed that fitting precision with Horton's model was higher than that with Philip's equation.Soil moisture content was found to have a negative correlation with initial infiltration rate,but not with steady-state infiltration rate.A negative correlation w... |
