中文摘要：

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。

英文摘要：

Studying on distribution characteristics and influencing factors of high-fluoride groundwater is closely related to local drinking water safety and utilization and protection of groundwater.This article used mathematical analysis and MAPGIS software etc.to analyze macroscopically the distribution characteristics and influence factors of F-mass concentration in 22 groundwater samples collected from plain area of Aksu prefecture.Several measures to deal with the problem of high-fluoride groundwater were proposed.The results show that F- mass concentration in plain area of Aksu Prefecture was higher in east and west and lower in central area;F- mass concentration was positively correlated with the pH value,mass concentration of Mg2＋ and ρ（K＋＋Na＋）/ρ（Ca2＋） ratio,and negatively correlated with mass concentration of Ca2＋ and HCO-3,and it was no significant correlation with mass concentration of K＋＋Na＋,Cl-,SO42- and TDS.
