摘　　要：针对城市化发展带来的城市热岛效应愈加突出等问题,以2021年宝鸡市建成区为例,利用Landsat 8 OLI影像基于辐射传输方程法进行地表温度反演,与开源气象站点数据进行温度改正后,得到宝鸡市建成区地表温度整体的空间分布,通过下垫面地表覆盖情况验证了结论的正确性,并分析了通风廊道对宝鸡市建成区热岛效应的缓解功能,以期为城市的形态、功能布局、城市景观、城市规划及决策提供重要的数据支撑和理论依据。In response to the increasingly prominent urban heat island effect brought about by urbanization,this article uses built-up area of Baoji City in 2021 as a case study.Utilizing Landsat 8 OLI imagery,surface temperature retrieval was conducted based on the radiative transfer equation method.After correcting the temperature using data from open-source meteorological stations,the overall spatial distribution of surface temperature in Built-up area of Baoji City was obtained.The validity of the conclusions was verified through the analysis of underlying surface cover conditions.Furthermore,this article analyzes the potential function of ventilation corridors in mitigating the urban heat island effect,aiming to provide crucial data support and theoretical basis for urban morphology,functional layout,urban landscape,urban planning,and decision-making.
