New construction has resulted in impervious surfaces increasingly replacing natural landscapes, altering surface radiation, thermal properties, and humidity in urban areas. Based on Landsat-8 data, the temporal and spatial impacts of the construction of Dalian Jinzhouwan Airport and Beijing Daxing Airport on the thermal environment were studied. The local thermal gradient (LTG) of the airport before and after construction is compared. The results showed that after the completion of the airport, the LTG value of Daxing Airport increased by 0.033 and that of Jinzhou Bay Airport increased by 0.009. After the airport operation, LTG values increase again. Daxing Airport added another 0.053, and Jinzhou Bay Airport added another 0.127. Two land classification models (land use type, LUT; local climate zone, LCZ) were used to explore the relationship between land use type and LTG. The results show that the increase of alloy buildings after the completion of the airport has a great influence on the thermal environment of the two study areas. The operation of airports will further enhance this effect. Our study can provide a reference for the influence of large-scale traffic construction on the urban thermal environment.
新的建筑导致不透水面越来越多地取代自然景观，改变了城市地区的表面辐射、热特性和湿度。基于 Landsat-8 数据，研究了大连金州湾机场和北京大兴机场建设对热环境的时空影响。比较了机场建设前后的局部热梯度（LTG）。结果表明，机场建成后，大兴机场的 LTG 值增加了 0.033，金州湾机场增加了 0.009。机场运营后，LTG 值再次增加。大兴机场增加了 0.053，金州湾机场增加了 0.127。利用两种土地分类模型（土地利用类型，LUT；局部气候区，LCZ）探讨了土地利用类型与 LTG 的关系。结果表明，机场建成后合金建筑的增加对两个研究区域的热环境有很大影响。机场的运营将进一步增强这种影响。本研究可为大型交通建设对城市热环境的影响提供参考。
