摘　　要：以2014~2020年的Landsat 8 OLI遥感数据为数据源,采用TIRS10单窗算法反演石家庄地表温度,通过研究石家庄地表温度与土地利用类型的关系,分析土地利用类型对地表温度的影响。结果发现:在2014~2020年,石家庄的建设用地面积增加,水域、耕地等地表覆盖类型面积减小,并且林地、水域、耕地和草地的平均温度都小于建设用地。因此,为了降低城镇发展对地表温度的影响,应该增加植被的种植面积和水域面积。Taking the Landsat 8 OLI remote sensing data from 2014 to 2020 as the data source,TIRS10 single-window algorithm was used to invert the surface temperature of Shijiazhuang,and the influence of land use type on surface temperature was analyzed by studying the relationship between land surface temperature and land use type in Shijiazhuang.The results show that from 2014 to 2020,the area of construction land in Shijiazhuang increased,the area of surface cover types such as water area and cultivated land decreased,and the average temperature of forest land,water area,cultivated land and grassland was less than that of construction land.Therefore,in order to reduce the impact of urban development on land surface temperature,the planting area and water area of vegetation should be increased.
