摘要
对西安市大气环境中二氧化硫、氮氧化物、总悬浮微粒和降尘等四种主要污染物的平均浓度随时间变化趋势做了初步分析 ,并利用模糊综合评判模型对各年大气环境质量状况进行了综合评价 。
Xi'an is a key region of carrying out West Development program and a seriously polluted city in china, so it is very essential to improve and evaluate Xi'an's air quality. In connection with a progress that the municipal administration has made during protecting and improving Xi'an's air quality in recent years, in this study, SO\-2?NOx?TSP and dust are regarded as main influent factors which average consistency's variable trends are analogized. Then, the fuzzy set theory is applied to evaluate comprehensive air quality of Xi'an from 1991 to 2000.
