摘　　要：针对西安市环境空气质量,使用显著性分析、t检验、灰色关联度分析、灰色预测等方法,建立t检验、灰色关联度分析、灰色预测及Markov链等模型,利用Excel、Matlab等软件对数据进行处理及函数编程,得到以AQI进行空气质量检测结果更为严格的结论以及季节、降雨量、可吸入颗粒物等多种因素与西安市环境空气质量的关系,最后预测出2013年4月30日至5月6日西安市的空气质量状况。The methods including significance analysis, t text, grey relational analysis and grey prediction are used to set up relevant models on the basis of the air quality in Xi＇an. The software such as Excel, and Maflab etc. are adopted to process the data and program the function, which indicates that the results of the air quality tested by AQI standard is more accurate and the factors including season, rainfall and inhalable particle are related to the air quality in Xi＇an. Finally, the paper predicts the air quality in Xi＇an from April 30th to May 6th in 2013.
