目的将模糊数学的方法引入到中国边境地区西北段饮用水质量的评价中,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,为中国陆地边境地区西北段饮用水质量评价提供科学依据。方法按随机原则选取中国边境地区西北段的16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,但部分水样存在卫生安全隐患。结论应用模糊数学方法综合评价中国边境地区西北段饮用水质量,克服了以往用单一指标的不足,客观反映出饮用水质量的实际状况,评价方法具有较高的实用价值。
OBJECTIVE To introduce the fuzzy mathematics method into the evaluation of drinking water quality in the northwestern part of China’s border area, aiming to summarize a large number of monitoring results and reach the conclusion that the comprehensive health status of water quality can be analyzed in depth and quantitatively, The northwestern border of drinking water quality assessment to provide a scientific basis. Methods According to the principle of randomness, 16 water sources were selected in the northwestern section of China’s border region. Based on the field investigation and laboratory tests, fuzzy mathematics method was used to describe the classification limits of water quality by using membership degree. Through the fuzzy matrix compound operation, the comprehensive evaluation result. Results The overall water quality was good. The water quality categories were mainly Class I and Class II, but some water samples had health and safety risks. Conclusion The fuzzy mathematics method is applied to evaluate the quality of drinking water in the northwestern part of China’s border areas, overcoming the shortcomings of using a single indicator in the past and objectively reflecting the actual status of drinking water quality. The evaluation method has high practical value.
