针对渭北黄土原灌区地下水位上升问题，提出了地下水新含水层的概念。并以宝鸡峡、羊毛湾灌区为例，介绍了新含水层的分布及厚度，分析了新含水层的形式条件在此基础上，进行了地下水资源评价，进一步证明新含水层已构成渭北黄土原灌区巨大的地下水库。 In view of the rising groundwater level in Weibei Loess Original Irrigation District, the concept of new aquifer of groundwater is proposed. Taking Baojixia and Yangmaowan irrigated areas as an example, the distribution and thickness of new aquifers were introduced. The formation conditions of new aquifers were analyzed. On the basis of this, the groundwater resources assessment was carried out to further prove that the new aquifer has formed the Weibei loess The original irrigation area huge underground reservoir.
