摘要：文中采用土壤深层水量渗漏测试记录仪对库姆塔格沙漠地区多坝沟季节性河道1.5m深处的水分渗漏过程进行了实时监测与人工模拟实验。结果表明：1）在自然流水过程中,上游有泉水维持,长期流水河段水分渗漏速率的波动幅度为0.1750～0.6042mm/min,平均值为0.3444mm/min;2）下游间歇性过水河段在无水期,基本没有渗漏,有水流过期间的水分渗漏速率的波动幅度为0.0059～0.6073mm/min,平均值为0.0809mm/min;3）水层深度的变化对土壤渗漏速率影响显著,当水层深度增加时,渗漏速率呈现先增加后稳定的趋势,当水层深度下降时,土壤渗漏速率随之降低;4）自然记录与人工模拟的结果均表明：间歇性来水时,大约历时4～6h就可以入渗到1.5m深度,而每次退水后（断流后）渗漏速率逐渐减小,但这个过程维持8～10d时间。
The process of deep permeation（1.5m） of seasonal river of Kumtag desert was monitored and simulated with the logger of deep soil water leakage.The result shows that：（1） The range of deep permeation rate was from 0.1750mm/min to 0.6042mm/min in upstream where the perennial spring flowed,and with an average value of 0.3444mm/min.（2） In downstream,there was no deep permeation in water-free period,but the average deep permeation rate was 0.0809mm/min when water flowed,and the range of deep permeation rate was from 0.0059mm/min to 0.6073mm/min.（3） The depth of water had a significant impact on the average deep permeation rate.When the depth of water increased in the storage tank,the average deep permeation rate increased at the beginning,and then remained steady,but when the depth of water decreased in the storage tank,the average deep permeation rate decreased also.（4） The water infiltration process from ground surface to 1.5m underground took 4-6 hours,and the deep permeation rate decreased when there had no water on the ground,and the process of deep permeation disappeared in about 8-10days.
