摘　　要：目的将模糊数学的方法引入到我国西北绿洲生态系统的饮用水水质的评价中,旨在将大量的监测结果归纳综合,得出总的结论,以深入、量化分析水质的综合卫生状况,为确保绿洲生态的饮水安全提供科学依据。方法按随机原则选取西北绿洲生态系统的12个水源点,在现场调查和实验室检测的基础上,应用模糊数学方法,利用隶属度描述水质分类界限,经模糊矩阵复合运算,得出综合评价结果。结果水质总体良好,水质类别以Ⅰ类和Ⅱ类为主,但部分水样存在饮水卫生安全隐患。结论应用模糊数学方法综合评价西北绿洲生态系统的饮用水水质,克服了以往用单一指标的不足,客观反映出综合水质实际状况,评价方法具有较高的实用价值。Objective Fuzzy mathematics was introduced into the evaluation of the quality of the drinking water in the northwest oasis ecosystem so as to draw the general conclusion by summarizing the monitoring data. It could provide a scientific basis for assessing the quality of the drinking water in the northwest oasis ecosystem through in - depth and quantitative analysis. Methods Twelve drinking water sources in the northwest oasis ecosystem were selected by random sampling. On the basis of field investigation and laboratory test, fuzzy mathematics was introduced, and the membership grade was used to describe the classification boundaries of the drinking water quality. Comprehensive evaluation results were obtained by fuzzy matrix complex operation. Results The overall quality of the drinking water was good, and it mainly fell into Class I and Class 1I . But there were health and safety risks for some water samples. Conclusions Comprehensive evaluation of the quality of the drinking water in the northwest oasis ecosystem by fuzzy mathematics overcomes the shortage of the past evaluation system by single in- dex. It can objectively reflect the actual comprehensive quality of the drinking water. It has high value in practical use.
