Abstract:
With the rapid growth of economy of Yan’an city, the present water resources can not meet the city’ s demand by the year 2 015. The differences between demand and supply are about 28 300 m3 /d. To solve the long- term water shortage of Yan’an city, new sources of water supply need to be found. Through the analysis of water resources and hydrogeological condition in and near Yan’an city, the possibility of building new groundwater sup- ply field in these areas is ruled out. On the basis of 1∶ 200 000 hydrogeologic prospecting results for counties governed by Yan’an, this paper concluded the water-bearing stratum of Luohe group(Cretaceous System)phre- atic water, artesian water and Quarternary system phreatic water should be used as the future supplying water. Through analyzing the Cretaceous System, Quarternary system, the sections rich in groundwater were selected and the amount of groundwater in these areas was calculated. Base on the above results, three locations were cho- sen as areas where detailed hydrogeological survey need be launched.
