Abstract

Global warming and the heat islands of cities is one of the biggest challenges in the world today, as many conferences are held annually at the national and local levels to prevent, address and moderate this phenomenon around the world. Despite the considerable attention of the scientific community to this issue, in practice, the unbridled growth of cities undermines all equations and efforts of the scientific community. Due to the expansion of the city and consequently the expansion of the heat islands, the cool (cold) islands have received more and more attention. In this study, in order to understand the effect of spatial distribution of land uses in the spatial distribution of Cool Islands, first the surface temperature was calculated using Landsat 8 image processing and Single Channel Algorithm and then the maximum land use map similarity was obtained using the algorithm. Finally, the impact of land use on the formation of cool and warm islands was investigated. According to the results, the lowest number of Cool Islands was in Baharan, Niavaran and Darband, respectively, and on the opposite side, the highest amount of heat islands were in Bustan neighborhood, Shahid Bagheri town and airport, respectively. The results showed that the highest average temperature among the uses was related to cement / paved areas (48. 3 ° C) and the lowest average temperature was related to water use (32. 4 ° C). Based on the results and comparison of the percentage of each land use in areas with thermal islands and Cool Islands, in cold areas the share of vegetation and in warm areas the share of cement / paving is significant. With these interpretations, one of the most efficient ways to turn heat islands into Cool Islands is to use low-water plants in greenhouses called greenhouses.
