对常用的三种地下水水质评价方法即内梅罗指数法、模糊综合评价法、主成分分析法的原理和评价步骤进行了系统的介绍，并将它们应用于娄底市丰水期地下水水质评价。从评价结果的过渡性、优劣性、相关性以及各水质监测井间的差异性，来对比分析内梅罗指数法、模糊综合评价法和主成分分析法间的差异。结果表明：主成分分析法所得结果过渡性最好，但偏于悲观，在各点评价结果波动较大，不能有效揭示各水质监测井水质的变化趋势；模糊综合评价法评价结果过渡性较差，但与单指标评价结果吻合较好，能够客观地反映各点水质状况；内梅罗指数法评价结果的过渡性与模糊综合评价法相似，但评价结果与单指标吻合程度不如模糊综合评价法。评价结果可为娄底市地下水水质评价提供基础数据。
