| Abstract: | 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. |
