Based on the daily datasets ofhaze, relative humidity, visibility at 14:00, air temperature, wind speed and radiation from 90 national meteorological stations in the Beijing-Tianjin-Hebei region (BTH) during 1961~2016, the climate change in BTH on haze days was analyzed by using the methods of MASH, linear regression, correlation analysis and Mann-Kendall. The results suggested that: the annual mean haze days in BTH showed an obvious enhanced trend, the increase was above 5d/10a, and the haze days in the middle and large cities were obviously higher compared to other areas. The sharp increase of haze days began in 1991~1992. The annual mean haze trend was slowed down under the initiation of special funds for the air pollution prevention and control. The daily mean temperature of haze and non-haze days showed an upward trend in BTH, whereas annual visibility decreased. The overall trend of annual precipitation decreased in BTH. The annual precipitation days of haze daily increased, while it showed a decreasing trend in non-haze days. The annual mean wind of haze and non-haze days in BTH decreased. The haze day increased with the enhanced GDP and energy consumption. The annual mean total radiation and scattering radiation of haze and non-haze days had been decliningin BTH. The declined trend of haze days is more obvious in contrast with non-haze days, and the annual mean total radiation is decreased remarkable than the scattering radiation. The annual mean haze days were negatively correlated with annual mean values of radiation, wind speed and precipitation, but positively correlated with annual mean variables of temperature, GDP and energy consumption.
