Abstract: This paper quantified the impact of land use change on thermal environment of Beijing, Tianjin and Hebei based on Landsat TM/ETM remote sensing data and WRF simulation and mathematical statistics method, and four schemes of experiments with different land use data were designed so as to find the spatial interactive impact of land use change . The results showed that: Firstly, during 2000-2015, urban construction land increased by 2 840 km2, mainly transferred from farmland and wetland which accounted for 94.37% and 4.93% of the increase of construction land, respectively. Secondly, Langfang, Tianjin and Tangshan are three cities most affected by land use change in Beijing, while Langfang was mostly affected by land use change in Tianjin. However, the temperature of other cities was less affected by land use change that the impact of land use change process in these cities is much smaller than in Beijing. Thirdly, from the perspective of seasons, the temperature in Beijing and Tianjin was most sensitive to land use change in autumn, followed by summer and spring, and basically had no response in winter through 2000-2015. Fourthly, land use change in areas other than Beijing increased the annual average temperature of Beijing by 0.07 ℃, but had obvious cooling effect in summer. As for Tianjin, land use change in other areas had little effect on temperature. Temperature rising area in autumn and winter formed a contiguous space of Beijing-Tianjin (Baodi District, Wuqing District, Jixian County). In view of this, we should construct urban ventilation corridors, promote the use of cleaner energy sources and upgrade the construction of urban green space system to optimize the thermal environment in the urban agglomeration of Beijing-Tianjin-Hebei. At the end of the paper, countermeasures and suggestions for building urban ventilation corridors, promoting the use of clean energy, improving energy efficiency, and scientifically planning urban green space system were put forward.

Key words: Beijing-Tianjin-Hebei urban agglomeration, land use change, thermal environment, WRF model
