【Abstract】 With the problem of the underground water table rising in the irrigatedarea on the weibei Loess Highland,this paper suggests a concept of the underground wa-ter new aquifer.Taking Baoji Gorge and Yangmao Wuan irrigation systems for example,this paper analyses the distribution,thickness and forming conditions of this new aguiferon the basis of which an evaluation of the underground water resources in made,thus,confirming that this new aquifer has formed a huge underground reservoir in the irriga-tion system on he Weibei Loess Highland.更多还原
