渭北黄土台原区,地面平阔,土质肥沃,是我省利用黄土地下水和引用地表水灌溉的主要地区,面积达万余平方公里。广大黄土台原区,经长期地表水灌溉后,产生了潜水位的大面积、大幅度上升,大面积黄土湿陷的发生以及老滑坡的活化、新滑坡的加剧等产生了一系列黄土水文地质工程地质问题。因此研究“黄土地下水的赋有条件与运移特征”不
Weibei Loess Plateau area, the ground flat, fertile soil, is the use of loess groundwater in our province and the reference surface water irrigation main areas, an area of 10,000 square kilometers. After a long period of surface water irrigation, a large area of the phreatic water level has risen sharply. The occurrence of large-scale loess collapses and the activation of old landslides and the intensification of new landslides have led to a series of loess hydrogeological projects Geological problems. Therefore, we study “the conditions and migration characteristics of loess groundwater”
