当前在开发利用地下水的同时,包气带水分的赋存与运移问题及其对地下水的形成与补给作用,引起了人们的关注。大家知道,饱和带与包气带是地下水同一连续系统中的两个部分,二者不可分割。包气带中水分下渗,其数量与速率决定了地下水的储量与动态,反之,地下水的变化影响着包气带水分剖面及其运移条件。尤其是黄土地区特定的自然地理条件下,
At present, while exploiting and utilizing groundwater, the occurrence and migration of moisture in the aeration zone and its role in the formation and recharge of groundwater have aroused people’s attention. We all know that the saturation zone and the aeration zone are two parts of the same continuous system of groundwater, both of which are indivisible. The amount and rate of water infiltration in the aeration zone determine the reserves and dynamics of the groundwater. On the contrary, the variation of the groundwater affects the moisture profile and the migration conditions of the aeration zone. Especially in the loess area under the specific natural and geographical conditions,
