Inversion Study of Urban Surface Temperature in Luoyang City Based on Landsat Images
In order to study the relations between the urban development of Luoyang and the urban heat island,the surface temperatures of the urban area in the past two decades were taken as the research object.Landsat satellite remote sensing data was used as the data source,and the temperature inversion method was used to study the surface temperatures at four different periods.The analysis was conducted by using ArcGIS,ENVI 5.3,and Origin 2018 software.The spatial distribution and spatiotemporal variation characteristics of the heat island effect,as well as the relations between surface temperature and land use type,were obtained.The results indicated that from 2001 to 2019,the surface temperature of the old city center(Xigong District)increased by 15℃,and the surface temperature of the new city center(Luolong District)increased by 11℃.Among different land use classifications,the surface temperature of water bodies was the lowest,and with the increase of the heat island,the cold island effect of water bodies had slightly increased.The surface temperature of the Luo River was 26℃in 2001,with a cold island intensity of 12℃,and in 2019,it was 34℃with a cold island intensity of 14℃.
