The regional air quality model CAMx was used to simulate the source contributions from Erdos, Ningdong and Xilingol (ENX) to the Beijing-Tianjin-Hebei region (BTH). The air quality impacts on the BTH region were evaluated using projected future emission inventory with the emission data from the approved environmental impact assessment, air quality planning and strategic planning, and the current emission inventory in ENX as two different scenarios. The results showed that the modeled contributions of PM2.5, SO2 and NOx from energy bases in ENX to BTH were in the ranges of 0.079~1.134μg/m3, 0.012~0.633μg/m3 and 0.008~0.852μg/m3, respectively with current emissions. The impacts from ENX on BTH were higher in winter with the averaged values of 0.710, 0.339 and 0.413μg/m3, respectively than that in summer. It has greater influence on air quality in Hengshui, Shijiazhuang, Xingtai, Handan and Baoding than the other cities in BTH. The modeled contributions of PM2.5, SO2 and NOx from energy bases in ENX using future emissions to BTH were in the ranges of 0.049~0.773μg/m3, 0.003~0.176μg/m3 and 0.008~0.731μg/m3, respectively, with the averaged values of 0.475,0.096, and 0.357μg/m3 in winter.
