The urban heat island effect is a common phenomenon during urbanization, characterized by significantly higher temperatures in urban areas compared to surrounding rural areas. Sensible heat flux (H) and temperature are important factors affecting the urban heat island effect. By optimizing the calculation of sensible heat flux, the urban thermal environment can be assessed more accurately, thereby guiding urban planning and green space layout to mitigate the heat island effect. This study proposes a method to optimize the calculation of sensible heat flux by combining low-pass filtering and wavelet transform. Low-pass filtering removes high-frequency noise, while wavelet transform extracts multi-scale fluctuation components, thereby improving the accuracy and stability of sensible heat flux calculations. Experimental results show that this method significantly enhances the precision of sensible heat flux calculations and reduces noise interference, providing reliable data for urban thermal environment research. This paper discusses in detail the application of this method in the study of the urban thermal environment in Jiangsu Province.
