Previous studies pointed out that human activity is one of the causes of the heat island effect. In Taiwan, more and more seasonal tourism activities are held in recent years along with the improvement of the life quality. However, such activities attract a lot of crowds and traffic flow and change the heat island intensity.
In order to monitor this effect, this study uses thermal infrared channels of Landsat series imagery and retrieves the ground temperature based on the methodology proposed by Jiménez-Muñoz et al. (2014) and Rozenstein et al. (2014). Xinshe flowery field in Taichung City is chosen to monitor the change of heat island effect at different periods. With supervised maximum likelihood classification, land features are divided into four categories: water, soil, impervious surface and vegetation; and then the emissivity values are assigned to each category.
The results show that the relatively high temperature regions are the areas with not only impervious surface but also frequent human activities. Land surface temperature of the flowery field is indeed rising during the seasonal activities. Besides, the land surface temperature in the flowery field is as high as other heat areas in Taichung, such as: Tali Industrial District, Taichung Thermal Power Plant. This confirms that transient traffic and human activities can influence the land surface temperature.
