陇东盆地环河组地下水富水性普遍弱,且复杂,但受岩性岩相、孔隙度、补给条件三个方面因素的影响和控制,在空间上具有中东部强西部弱,下部强上部弱的富集规律,这对当地的城市生活供水和陇东能源基地供水方向具有一定的指导意义。 Due to the influence and control of lithofacies, porosity and recharge conditions, the groundwater in the Huanhe Formation of the Longdong Basin is weak and complex. However, it has strong weakness in the west and weak in the middle and strong in the lower part Enrichment law, which has some guiding significance to the local urban water supply and Longdong energy base water supply direction.
