ASSESSMENT OF VEGETATION COOLING EFFECT ON THE SURROUNDING THERMAL ENVIRONMENT IN BLOCK SCALES

Liu, Y. P.; Cai, G. Y.

The growing coverage of impervious surfaces within cities has resulted in a decrease in vegetation areas, which in turn has caused the temperature increase in urban region. It has proved that vegetation plays an important role in mitigating urban heat island (UHI) effects such that the city managers and planners have paid more attention on how to plan green lands in city planning related projects. This paper focuses on the detection of the mean land surface temperature (LST) change in residential blocks in Changchun where citizens are have common daily lives. Then, according to the interactive extraction of high spatial resolution images, the regions with great changes in Changchun city during 2016 and 2019 are analyzed and compared with the average surface temperature of each block. According to statistical methods, the mitigation effect of the green space on the plot was obtained. It is helpful for city managers or planners to create a livable environment for citizens.
