张家口市坝下山区岩溶水的富集规律研究

Study on the Enrichment Regularity of Karstic Water in Mountainous Area of Zhangjiakou

张家口市坝下地区位于河北省西北部,水文地质情况较复杂,区内碳酸盐岩地层分布较广,地下裂隙岩溶水资源较丰富。根据相关水文地质资料,分析总结了可溶岩地层的厚度、岩性及岩性组合、分布面积、地质构造及地形条件等因素对岩溶水富集规律的影响和控制,阐明了区内岩溶水的供水意义。

Located in the northwest of Hebei Province, the dam area in Zhangjiakou is featured with complex hydrogeologi-cal conditions, wide distribution of carbonate rocks and rich karstic groundwater. By analyzing influence of thickness, litholo-gy, lithological association, distribution, geological structure and geological conditions of karstic formations on the enrichment regularity of karstic water, this paper figures out the significance of karstic water in this region for water supply.
