Title

Investigating the role of urban growth pattern in creating thermal islands in cities (Case study: Sari city)

Pages

  77-94

Abstract

 This study examines the role of Urban growth pattern in the creation of thermal islands in cities (Case study: Sari city), the type of expansion of Sari city and then the characteristics of the city's thermal zones and identifies its relationship with the formation of urban thermal islands. The unplanned and increasing expansion of cities over the past half century has led to environmental problems. These environmental problems can endanger the quality of life of citizens and consequently their health. One of these problems is the phenomenon of urban heat islands. Urban heat islands are a phenomenon in which the temperature of some areas is higher than other neighboring areas. This phenomenon can be the result of the scattered growth of cities as well as the unplanned and vertical growth of some urban areas. Urban heat islands in different areas can have negative consequences,The first is the issue of human health that the presence of thermal islands in cities causes a phenomenon of lack of temperature comfort and also exacerbates air pollution, a phenomenon with which we are often involved in Iranian cities. This research is analytical, but it should be added that it will be practical in terms of purpose. In the practical dimension, the results can be used in urban decision-making and planning. Landsat 8 satellite data was used for this study. In this regard, after preparing the images, the temperature map of Sari city is prepared using remote sensing techniques and GIS software, and then the thermal islands are extracted. Similarly, the vegetation and land map will be prepared and the Shannon entropy coefficient and building density and population will be calculated and compared with urban heat islands. The results of this study show that the formation of thermal islands in the city of Sari depends on both types of urban growth and the creation of thermal zones has a significant relationship with the type of land cover, population density and construction. Also, most of the current thermal areas of Sari include areas that have been added to the city in recent decades. Also, in order to prevent the formation of new thermal zones and control the growth of existing thermal zones, according to the thermal characteristics of each zone, suggestions are presented.
