摘　　要：松源市地处干旱半干旱地区 ,农业灌溉是粮食增产非常重要的措施。在灌溉中水质是保证粮食和土地质量的非常关键的问题。在分析灌溉用水水质评价方法的基础上 ,采用模糊综合评判的方法 ,选择酸度、碱度和矿化度为评价因子的计算方法 ,同时简述了模糊综合评判方法的原理及四种评价模型。用实例说明了评价步骤 ,最后对松源市地下水灌溉水质进行评价 ,其结果合理、可信。Songyuan lies in a half-dry region. Agriculture irrigation is an important method for increasing grain production. Water quality is the key to guarantee quality of grain and soil. Based on analyzing method of water quality evaluation, we adoptthe method of fuzzy synthetic evaluation, select the degree of acidity,alkalinity and minerality as evaluating factors. We briefly described the principle about this method and four evaluation models, then we show the evaluation course by example. At last, we give the evaluation about underground water in Songyuan. The results are reasonable and credible.
