摘　　要：基于乌鲁木齐市2015年大气污染物和气象观测数据,用相关性分析和主成分分析法探讨了气象因素对乌鲁木齐市城区空气质量的影响。研究结果表明:1)大气压与PM_(2.5)、CO正相关显著,与O_3负相关显著;气温、水汽压和风速与PM_(10)、O_3存在显著正相关,与其他污染物都存在负相关;湿度与PM_(2.5)、SO_2、NO_2、CO存在显著正相关,与PM_(10)、O_3存在负相关。2)对乌鲁木齐市首要污染物PM_(10)存在显著影响的空气污染物包括CO、PM_(2.5)、SO_2,气象影响因素包括水汽压和湿度。Based on the daily atmospheric pollutants concentration in Urumqi city in 2015 and the meteorological observation data,by using the correlation analysis and principal component regres-model,the research discussed the influence of meteorological factors on the air quality in Urumqi. The results showed that： the correlation between P（ atmosphere） and PM2.5、CO were significant negative,while that of P（ atmosphere） and O3 was significant positive. The correlation between and PM10,O3 were significant positive,while that of T（ temperature）,Pa（ vapour pressure）,V（ wind speed） and PM2.5,SO2,NO2,O3 were significant negative. The correlation between RH and PM2.5,SO2,NO2,CO were significant negative,while that of RH and PM10,O3 were significant positive. And the CO,PM2.5,SO2,Pa,RH had significant influence on PM10,the primary pollutant in Urumqi.
