Abstract：In order to study the temporal and spatial distribution characteristics of ozone in Beijing-Tianjin-Hebei region and estimate the regional transport contribution, the principal component analysis was carried out on the data of 68 national control stations in Beijing-Tianjin-Hebei region from 2017 to 2019, and the TCEQ method was used to estimate the background concentration of ozone in Beijing-Tianjin-Hebei region and subdivided sub-regions. The results showed that the ozone concentration in Beijing-Tianjin-Hebei region was high in the south and low in the north as a whole, and the difference of geographical location and its distance had great influence on the uniform distribution of ozone concentration in different cities. After the rotation of the maximum variance method, the Beijing-Tianjin-Hebei region could be divided into three subregions:the central and southern part of Hebei Province, the north of Beijing-Tianjin-Hebei region and the west coast of the Bohai Sea. Using the TCEQ method to estimate the ozone background concentration in the three subregions could reduce the influence of geographical factors. The calculated results showed that the locally generated ozone concentrations in the three subregions are 71, 60 and 59μg/m3, respectively, and the ratio of the regional background concentration to the maximum 8-hour concentration in ozone days was 34.3%, 39.4% and 42.2%, respectively. The local generation of ozone in Beijing-Tianjin-Hebei region was dominant, and regional transmission could not be ignored.
