| 摘 要： | 焦作裂隙岩溶水系统是我国北方岩溶区发育比较典型的系统之一,岩溶水资源丰富,水质优良,是城市供水的主要水源.据近几年水质监测,岩溶水Cl-逐年增加,水质变咸.在对焦作矿区地质、水文地质条件、岩溶水补给来源、地表污染源和污染途径分析的基础上,建立了二维非稳定溶质运移数值模拟模型,模拟了岩溶水Cl-时空分布,证实岩溶水Cl-升高是人为污染所致,不同区域岩溶水有不同的污染源和污染途径.

| Abstract: | Jiaozuo coal mine is a typical North China coal field of Permo-carboniferous period, the karst-fracture groundwater is abundant and high-quality, and it is also the main water supply resource of Jiaozuo city. According to water quality monitoring, karst groundwater has been polluted by Cl -, and it is changing salty in this paper firstly geological and hydrogeologic conditions as well as contaminant sources and channels were analyzed and then was Cl - space-time distribution simulated in karst groundwater by a two dimensional solute travel analogue model.All of these proved that Cl - contaminant in karst ground water is caused by man-made factors,and different area has different pollution sources and routeways. |
