摘　　要：城市空气污染严重影响着城市的发展和人民的健康,为了研究城市空气污染的影响因素对于污染的影响程度和类型,采用了灰色系统理论中灰色关联分析方法的斜率关联度模型。以广州、西安和乌鲁木齐为研究对象,选取了几个具有典型的空气污染因素。结果表明:对于这三个城市而言,燃煤都是空气污染的最主要污染因素,而对于不同的城市,其他污染因素对于不同污染物有着不同的影响,在污染治理的时候要分析城市具体所存在的首要污染物以对症下药。Urban air pollution seriously affects the development of the city and the residents＇ health. In order to analyze the influence degree and types of the factors influencing on urban air pollution,slope correlation degree model of grey correlative analysis based on grey system theory was applied in the research. Guangzhou,Xi＇an,and Urumchi were regarded as study objects,and several typical air pollution factors were chosen. The results showed that coal combustion is the major pollution factor to the three cities,and the effects of industrial pollution and private vehicles differ in different cities. The major pollution factors should be analyzed and the corresponding measures need to be taken for air pollution control.
