The　impact　of　the　air　quality　from　thermal　power　industry　was　analyzed　quantitatively　based　on　WRF-CAMx　model.　The　results　indicated　that　contribution　rates　to　the　annual　average　concentrations　of　SO2,　NO2,　PM2.5,　sulfate,　nitrate　and　primary　PM2.5　from　thermal　power　plants　were　15.6%,　19.6%,　8.5%,　11.7%,　12.0%　and　5.2%,　respectively.　There　was　a　general　characteristic　that　in　regions　where　air　pollutions　were　more　severe,　the　contribution　rates　from　thermal　power　plants　were　reversely　lower.　Specially,　in　Beijing-Tianjin-Hebei-Shandong-Henan,　Yangtze　River　Delta,　Wuhan　and　Changsha-Zhuzhou-Xiangtan　city　clusters　located　on　the　Plain　and　the　Chengdu-Chongqing　area　where　air　pollutions　were　the　most　serious,　the　PM2.5　contribution　rates　from　the　thermal　power　industry　were　less　than　8%.　Improvement　to　the　atmospheric　quality　due　to　ultra-low　emission　in　thermal　power　industry　was　not　obvious.　In　view　of　this,　policy　of　multi-pollutant　control　should　be　also　implemented　in　other　industries　besides　thermal　power　plants　in　order　to　improve　atmospheric　quality.　©　2016,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
