| Today, the per capita green space in Shiraz metropolis is decreasing due to the increasing physical expansion and frequent land use change. The purpose of this research is to investigate the effects of urban green infrastructure on the reduction of the heat island phenomsenon of Shiraz metropolis through the processing of Landsat 8 satellite images by Fragstats and Arc Gis 10.3 software, which are compiled through the two processes of landscape metrics and the preparation of LST maps. Is. Based on the findings of land surface metrics, human land use at the land surface level of each region shows that districts 11, 4 and 5 of Shiraz city have the highest percentage of human-made land use. On the other hand, the 10th and 3rd regions have the least man-made land use. The results show that in areas 3, 6 and 11 of Shiraz city, there is high temperature resulting from human activities, which indicates the existence of thermal islands. The highest temperature is related to the area of Bagh Delgosha to the side of the coastal pass. The 11th and 9th district of Shiraz city has the best environmentally friendly form with a design method more compatible with the environment in the south-eastern direction, and the difference between the highest and the lowest temperature does not reach 20 degrees Celsius. Therefore, the existence of urban green spaces play an effective role in reducing heat islands. | ||
