中国边境地区西北段饮用水质量的模糊数学评价

Fuzzy mathematics evaluation of drinking water quality in northwest border of China

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 fuzzy mathematics method to evaluate drinking water quality in northwest border of China, based on summarizing monitoring results, so as to provide a scientific basis for drinking water quality assessment in northwest border of China through in - depth and quantitative analysis. Methods On the basis of field investigation and laboratory testing, sixteen drinking water source sites were randomly selected to evaluate the water quality by fuzzy mathematical methods, including water quality classification boundary description by membership and fuzzy matrix compound operation. Results Drinking water quality was overall good, mainly grade I and II , but potential safety hazards were found in some water samples. ConcluSion Fuzzy mathematics comprehensive evaluation for drinking water quality in northwest border of China has overcome the shortage of single index evaluation system, and objectively reflected the actual status of drinking water quality, showing high practical value.
