The effect of urban design principles on climate change in the urban transects of Mashhad

The man-made system, including buildings, transportation and industry, has a significant share in the phenomenon of climate change in the world. Cities are the mainstay of human construction. Inadequate urban planning principles, especially in less developed countries, have multiplied the phenomenon of global warming and climate change in recent decades. Therefore, the purpose of this article is to investigate the impact of urban design principles and indicators on the phenomenon of climate change. This research is a qualitative study that has been done in the practical part. According to the purpose, research is categorized as applied. In this regard, the positivist approach has been used.

The results of the research indicate that the buildings with a score of 0.5729 have the highest score in the sixth transect (central city center). Exchange and transportation spaces with the score of 0.1713 in the third transect (middle texture) has the highest score. Natural open spaces, public open spaces and streets with a score of 0.8146 in the first transect (suburbs and pristine areas) have the highest score in influencing the phenomenon of climate change.
