Research on Remote Sensing Monitoring of Urban Heat Island Effect:Taking Zhuhai City as an Example
In order to complete the correlation analysis between the heat island effect and land cover in Zhuhai city,multiple period Landsat remote sensing images were used to invert surface temperature based on a single channel algorithm. Land cover types were ex-tracted and classified using the index method. The distribution index was introduced to construct the heat island distribution index P to analyze the distribution and change patterns of the heat island effect in Zhuhai city,and achieve the spatial correlation analysis be-tween land cover and heat island effect. The research results indicate that the intensity of the heat island effect in Zhuhai has shown a continuous upward trend from 2013 to 2021,consistent with the growth trend of urban construction land and basically consistent with the actual development of the city.
