摘　　要：结合研究区水文地质条件及岩溶水赋存状况,采用灰色聚类和模糊综合评判相结合的方法,对该市岩溶地下水的水质进行了现状评价及污染变化趋势分析。结果表明:研究区岩溶地下水以Ⅲ类水为主,占监测井总数的58.3%,Ⅱ类水占16.7%,总体水质尚好;但个别监测井水质污染严重,主要为总硬度、可溶性总固体和大肠杆菌超标。部分监测井中的Cr^(6+)质量浓度虽未超标,但有逐年恶化的趋势。Based on the hydrogeological conditions and karst water occurrence conditions in the studied area,the present situation evaluation and pollution trend analysis have been conducted on the karst underground water quality of this city through the combining methods of grey clustering and fuzzy comprehensive evaluation. Results show that Class III is the predominant type in the karst groundwater of the studied area,accounting for 58. 3% of the total number of monitoring wells; class II accounts for 16. 7%,with the water quality generally good; some individual monitoring wells are seriously polluted with over-standard hardness,soluble solids and Escherichia coli. Without exceeding the standard,Cr^6＋ concentration in some monitoring wells indicates a worsening trend.
