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 To introduce the method of fuzzy mathematics into the evaluation of drinking water quality in the ecosystem of northwestern oasis in China. The aim is to summarize a large number of monitoring results and draw the general conclusion, in order to make an in-depth and quantitative analysis of the comprehensive hygienic condition of water quality, Oasis ecological drinking water safety to provide a scientific basis. Methods According to the principle of random selection, 12 water sources of the northwestern oasis ecosystem were selected. On the basis of field survey and laboratory tests, fuzzy mathematics method was used to describe the classification limits of water quality by membership degree. The results of comprehensive evaluation . 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 of drinking water. Conclusion Fuzzy mathematics method is used to evaluate the quality of drinking water in the ecosystem of northwest oasis, overcoming the shortcomings of using a single indicator in the past and objectively reflecting the actual status of integrated water quality. The evaluation method has high practical value.
