摘　　要：为分析矿区城市雾霾天气的影响因素,收集了我国各矿区城市的雾霾天气统计数据,并采用最小二乘拟合的数学方法对收集到的数据进行分析。分析结果显示,影响雾霾天气频率的主要因素是百公里范围内工业企业数量和温度,湿度、煤炭产量和风速对雾霾天气频率的影响相对较小;雾霾天气的发生与季节也有很大关系,夏季雾霾天气频率最高,春季雾霾天气频率最低。To analyse the influencing factors of smog weather in mining areal cities, statistical data about smog weather at such a kind of cities around China were collected, and the least squares fitting method was applied. It has shown that the major influencing factors of smog weather included the number of industrial factories within hundred kilometres and air temperature, whilst air humidity, coal output and wind speed exerted relatively weak er influences on the occurrin g frequency of smog weather. Its occurrence was also closely related to the seasons, i.e., it occurred the most frequently in summer but did the least in spring.
