中文摘要	灌丛沙堆是旱区灌丛植被水文过程的快通道,也是调节土壤水分平衡的关键点.以荒漠草原退化人工柠条林为研究对象,通过人工沙埋的方式改变灌丛沙堆大小与形态,在连续监测分析基础上(2012 2016年),探讨了人工沙埋干预下灌丛沙堆土壤水文过程与水文效应的动态响应.结果表明:与对照相比,(1)沙埋干预并未显著改变表层010 cm主要的水文物理指标,但是显著提高了510 cm土壤水分入渗速率,同时05cm初渗率显著降低;(2)沙埋干预明显提高了降水后表层05cm土壤的即时持水性,同时降水后表层土壤水分含量衰减过程呈现出很强的季节性变化;(3)20122016年生长季末沙埋处理的0100 cm土壤相对储水率分别为11.3%,-6.5%,4.5%,4.3%,15.7%,这种效应集中在060 cm,对照处理下层土壤(60100cm)水分含量的波动性更强.总体而言,沙埋干预对表层土壤水文物理特性无显著影响,但是显著提高了510cm土层水分入渗性能并降低了05cm初渗率;但是这种局部入渗性能的加强并未提高水分补给深度,上下层间水文联系反而弱化.沙埋干预的长期水文效应及其作为旱化成龄人工林适应性管理措施的适宜性还有待进一步的跟踪监测与分析.
英文摘要	Nebkhas are the fast pathways for hydrological processes of shrub vegetation in arid regions,and also the key points for regulating soil water balance.Taking the degraded artificial Caragana intermdia in desert grassland asobject,the dynamic responses of hydrological processes and hydrological effects of Nebkhas by artificial sand buried were explored for five consecutive years(2012-2016).The results showed that the sand burial intervention did not significantly change the main hydrology physical indicators of 010 cm in the surface layer,but significantly increased soil moisture infiltration rate of 510 cm,while infiltration rate of the 05 cm was significantly reduced.The instant water capacity of 05 cm soil surface was significantly improved by the sand burial intervention.After the precipitation,the decay process of moisture content in surface soil showed a strong seasonal change.The relative storage effects of 0100 cm soil with sand burial at the end of the growing seasons in 20122016 were 11.3%,-6.5%,4.5%,4.3%,and 15.7%,and the increase of 060 cm was the most obvious.In general,the sand burial intervention had no significant effects on the hydrophysical characteristics of the surface soil.Water infiltration rate of soil 510 cm layer was significantly improved,but infiltration rate of the 05 cm was reduced.However,the enhancement of local infiltration performance did not increase the depth of water recharge,while the hydrological connections between the upper and lower layers were weakened.
