Analyses of Changes in Spatial Patterns in Temperature Heat Islands of Esfahan Province

This study was fulfilled aiming at the identification of spatial and temporal changes of temperature islands in Isfahan province First, a data basis of the highest and lowest net-based temperature and a committee were founded in Isfahan. Using the data of the basis, a statistical period of 35 years from 1980 to 2014 was chosen as the basis of the study and a geo with dimensions of 18 by 18 kilometers was spread on the area understudy. In order to access the during-year changes of the temperature islands of Isfahan, modern methods of spatial statistics such as Moran's I autocorrelation and hotspots in GIS environment were used. The results of the study showed that the changes of spatial and temporal in temperature islands of Isfahan possess a high cluster pattern. Based on the local Moran’s indicator and hotspot, the temperature islands of the east and north of the province have a positive spatial autocorrelation while the west and southwest areas have negative spatial correlation. During the study 41.45 of the province has not had any meaningful pattern or spatial autocorrelation. It was also shown that the temperature islands are controlled and affected by the local factors which control the space as well as the outside factors which control the time.
