摘　　要：塔里木盆地因地处干旱区腹地,其环境空气质量受人为、气候因素扰动,对人类健康以及生态环境安全造成了一定的影响。基于综合指数评价法,对塔里木盆地南缘巴州地区9县市“十三五”末(2020年)环境空气质量进行了时空分析,结果表明:“十三五”末,巴州环境空气质量总体较好,各县市环境空气质量优良天数总体范围为133~296 d,各县市综合质量指数在3.41~13.2之间,各县市中库尔勒市、博湖县、和静县、和硕县NO_(2)、PM_(2.5)年内月均值及季节均值均具有较为一致的变化趋势。各县空气质量指数从低到高依次是和硕、焉耆、博湖县、和静、尉犁、轮台、若羌以及末县,总体空气质量北部好于南部。各主要指标浓度变化主要受自然因素及人为活动的双重影响。Because Tarim Basin is located in the hinterland of arid area,its ambient air quality is disturbed by man-made and climatic factors,which has further affected human health and ecological environment security.Based on the comprehensive index evaluation method,this paper analyzes the ambient air quality of 9 counties and cities in Bazhou Area on the southern edge of Tarim basin at the end of “the 13 th five-year plan”(2020).The results show that at the end of “the 13 th five-year plan”,Bazhou’s ambient air quality is generally good;the overall range of days with excellent ambient air quality in each county and city is 133~296 days;the comprehensive quality index of each county and city is 3.41~13.2;the monthly and seasonal mean values of NO_(2) and PM_(2.5) have relatively consistent trends.From low to high,the air quality index of each county is Heshuo < Yanqi < Bohu County < Hejing < Yuli < Luntai < Ruoqiang < Qiemo county.The overall air quality in the north is better than that in the south.The concentration change of each main index is mainly affected by both natural factors and human activities.
