| 摘 要： | 通过对天山中部不同林龄天山云杉(Picea schrenkiana var.tianschanica(Rupr.)Chen et Fu)地表土壤和林外草地土壤进行实验室人工降雨模拟渗透试验,初步探讨了天山云杉林地土壤的入渗性能.结果表明:1)累积渗透量、入渗速率与入渗时间均呈幂指数相关关系.稳渗速率最高为近熟林1.91...

| Abstract: | Based on laboratory artificial rainfall and infiltration test on surface soil of central Tianshan Picea schrenkiana var.tianschanica forests in different forest age and grassland outside the forest,water infiltration ability of Picea schrenkiana var.tianschanica forests soil was assessed.The results showed:(1) Amount of cumulative infiltration,infiltration rate and infiltration time have power and exponential correlations.The highest steady-state permeability rate is 1.9108 mm/min;the lowest is 0.31847 mm/m... |
