Abstract
Land surface temperature in six specific time since 1980 s were retrieved from TM and ETM+ remotely sensed data.The temporal-spatial evolvement patterns were analyzed and the results showed that the range of urban heat island in Shanghai city enlarged,and so did intensity.The concentrated distributions of UHI gradually turned to dispersed situation.The sprawl of built-up area is the main cause of enlargement of UHI's range and intensity.Correlation and regression analysis suggest that there is obvious negative correlationship between vegetation abundance and land surface temperature.It is very important to decrease UHI by increasing vegetation abundance in urban environmental management.
