娘子关岩溶地下水分布及合理持久开发研究

娘子关泉域岩溶地下水是山西省阳泉市的主要水源地。根据岩溶发育与地层岩性、地质构造、新构造运动的关系 ,说明娘子关泉域中奥陶统灰岩与下奥陶统顶部地层岩溶发育不同 ,岩溶的垂向分布取决于地壳的新构造运动。指出娘子关泉域地下水主要补给来源为降水入渗 ,由此提出阳泉市岩溶水持久开发方案。

Distribution and Sustainable Exploitation of Karst Groundwater in Niangziguan Spring Region

Yangquan is a city short of water and mainly depends on karst groundwater in the Niangziguan spring region.Based on the relationships between the karst growth,the lithologic characteristics of the stratum,the geological formation and the new tectonic movement,it is pointed out that the growth of karst in the limestone of the Ordovician layer is different from that at the top of the lower Ordovician layer in the Niangziguan spring region,and that the vertical distribution of karst is determined by the new tectonic movement of the earth crust.In consideration of the fact that the recharge of groundwater there is mainly from precipitation,and on this basis,a scheme for sustainable exploitation of karst groundwater at Yangquan is proposed.
