为了解荆州市城区地下水化学状况,采集样品68组对14项水化学指标进行了测定,划分了水化学类型。结果表明,该区域地下水为单一的HCO3-Ca型和HCO3-Ca.Mg型水;主要离子Ca2+和HCO3-的主导性是由碳酸盐岩的风化溶解和地下水径流对离子的运移造成;并对污染来源进行了分析。
In order to understand the chemical status of groundwater in Jingzhou City, samples of 68 samples collected from 14 samples were used to determine the chemical indicators of water and the chemical types were divided. The results show that the groundwater in this area is a single type of HCO3-Ca and HCO3-Ca.Mg water. The dominant ions Ca2 + and HCO3- are mainly caused by weathering dissolution of carbonate rocks and groundwater runoff. The sources of pollution were analyzed.
