Spatial-temporal Evolution of Urban Heat Island Effect in Shanghai from 2000 to 2017

This paper selected Landsat remote sensing image of shanghai and radiation transfer equation for remote sensing inversion of land surface temperature. Through the inversion of the land surface temperature and grading the results,the spatial distribution characteristics of land surface temperature in summer was obtained. The research showed that the urban heat island effect in Shanghai was very significant,and the urban heat island indicated a further expansion trend.
