关中盆地蕴藏着丰富的地下水。作为地下水主要补给来源之一的河水。不仅在量的方面直接影响地下水资源的保证程度,而且在质的方面也直接影响地下水水质的形成及开采利用的可能性。现代水文网的分布,受区域地质构造、气候、地形、岩性等条件的制约,与地下水特别是潜水的形成条件具有密切联系。古水文网的分布及其水文地球化学特征在一定程度上亦控制着承压水的形成和分布规律。现代水系与古水
Guanzhong basin is rich in groundwater. River water, one of the major sources of groundwater recharge. Not only directly affects the degree of assurance of groundwater resources in terms of quantity, but also directly affects the formation of groundwater quality and the possibility of exploitation and utilization in terms of quality. The distribution of modern hydrological networks is closely linked with the formation conditions of groundwater, especially diving, because of the constraints of regional geological structure, climate, topography and lithology. The distribution of ancient hydrological networks and their hydrogeochemical characteristics also control the formation and distribution of confined water to a certain extent. Modern water systems and ancient water
