摘　　要：为了研究不同地质条件下影响地下水质量的指标差异,为地下水资源保护和开发提供参考。根据红层区和岩溶区不同的地质条件,分别采集水样进行测试,分析地下水化学特征。然后采用层级阶梯评价方法对地下水质量进行评价,得出影响水质的主要指标,并分析指标超标的原因。最后对比分析得出影响红层区和岩溶区水质指标的差异及原因。In order to study the difference of groundwater quality indexes under different geological conditions and provide reference for ground water resource protection and development,this paper collected water samples and tested to analyze the chemical characteristics of groundwater according to different geological conditions in the red layer areas and karst areas.Then the hierarchical ladder evaluation method was used to evaluate groundwater quality,through which the main indicators affecting the water quality was obtained.The reasons of the indicators exceeding standard was also analyzed.Finally,the reason that cause the difference of the groundwater quality between red layer areas and karst areas were discussed.

关 键 词：地下水化学 水质指标 质量评价 超标
