摘要
运用模糊数学方法,选用SO2、NO2、PM10作为评价因子,参照大气环境质量标准,通过计算污染因子权重分配系数和隶属度对徐州市总体大气环境质量给出客观的评价,综合评判结果表明徐州总体大气环境质量为中度污染(三级),但空气质量在逐年好转。用模糊概念进行推理,经过运算得出综合评价结果,与一般评价方法相比更接近客观。
The atmospheric environment quality of Xuzhou was evaluated by applying the method of fuzzy mathematics, selecting SO2 , NO2, PM10 as evaluation factors, consulting the standards relevant to atmospheric environment and calculating the weight, distribution coeficients of weight, grade attach -ment of atmospheric pollution factor. The result of comprehensive evaluation indicated that the atmospheric environment of Xuzhou was moderately polluted, but it was improved year after year. The result of comprehensive evaluation using the method of fuzzy mathematics was more objective than any other normal evaluation method.
