摘要:

以陕北风沙滩地区为研究区域，研究了次降雨及累计降雨对包气带和地下水的补给作用。结果表明，包气带浅表层的无效降雨量约为2.0 mm；对地下水补给的无效降雨量约为16.0 mm；降雨入渗过程中包气带各埋深处的滞后时间自上而下从1 h逐渐增加到 15 h。

Abstract:

Taking the wind-blown sand beach area of northern Shaanxi as the research area, the recharge of single precipitation and accumulative precipitation for the aeration zone and groundwater were researched. The results indicated that the ineffective precipitation for the surface was about 2.0 mm and the ineffective precipitation for groundwater was about 16.0 mm. From top to bottom, the lag time of all buried depths during precipitation infiltration increased gradually from 1 h to 15 h.

Key words: precipitation; moisture; buried depth of groundwater table; the wind-blown sand beach area of northern Shaanxi province
