研究区域高氟地下水的分布特征和影响因素与当地饮用水安全、地下水利用与保护息息相关。文中以阿克苏地区平原区22个地下水样为研究对象,运用数学分析及MAPGIS软件等方法从宏观上对该地区地下水F-含量的分布和影响因素进行分析。结果表明:阿克苏平原区地下水的F-质量浓度呈东、西部高,中部低分布;地下水的pH值越大,F-质量浓度越高。得出了F-质量浓度与K++Na+、Cl-、SO24-TDS、HCO3-质量浓度之间无明显相关性,与Mg2+、ρ(K++Na+)/ρ(Ca2+)之间存在着线性正相关关系,与Ca2+质量浓度之间存在着线性负相关关系的结论。并提出应对地下水高氟问题的几项对策。
The distribution characteristics and influencing factors of high-fluoride groundwater in the study area are closely related to the local drinking water safety, groundwater utilization and protection. In this paper, 22 groundwater samples in the plain of Aksu are studied. Mathematical analysis and MAPGIS software are used to analyze the distribution and influencing factors of groundwater F-content in this area. The results showed that the F-mass concentration of groundwater in the Aksu Plain was high in the east and west and low in the middle. The higher the pH value of groundwater, the higher the F-mass concentration. It is concluded that there is no significant correlation between the F-mass concentration and K + + Na +, Cl-, SO24-TDS, HCO3- mass concentration, and between Mg2 + and ρ (K ++ Na +) / ρ Linear positive correlation, and the concentration of Ca2 + there is a linear negative correlation between the conclusions. And put forward some countermeasures to deal with the problem of high fluoride in groundwater.
