Investigation of the components and zoning of urban morphology based on sustainable development; Case study: District one of Tabriz

The aim of this research is to explain the indicators of urban morphology based on sustainable development and evaluate the level of sustainability of neighborhoods based on these indicators. The present research is of a research-applied type. The indicators used in the research are building age, building materials, building quality, fractal index, texture status index, sky view factor (SVF), proximity to the main street, proximity to public transportation, proximity to shopping centers, proximity to Education centers, Normalized difference vegetation index (NDVI), Land Surface Temperature (LST) and Land Use Mixing. The results determined that Gol Park, Valiasr 1, Valiasr 3, Baghmishe Ghadim 3 are the neighborhoods with sustainable morphology. Also, Golkar, Valiasr 2, Kalantar Koocheh, Sangi Pol 1 and 2, Baghmishe Ghadim 1 and 2, Bilanko 1 and 2 are the neighborhoods with semi-sustainable morphology. In addition, the neighborhoods of Shahid Beheshti, Mullah Zeinal 1 and 2, Idealo 1 and 2, Yousefabad 1 to 3, Ghoshtkhaneh seylab 1 to 3, Valiasr 4, Abbasi 1 and 2 are the neighborhoods with unsustainable morphology. The results showed that neighborhoods with high social and economic status are generally sustainable neighborhoods and neighborhoods with low social and economic status and informal settlements including Shahid Beheshti alley, Mullah Zinal 1 and 2, Ideolo 1 and 2, Yousefabad 1 to 3, Ghoshtkhaneh seylab is 1 to 3, they are unsustainable. The total number of people living in neighborhoods with sustainable, semi-sustainable, and unsustainable morphology is 46.544, 79.603, and 89.851, respectively. Based on the results, texture status index, NDVI, and proximity to public transportation with weights of 0.18335, 0.12975, and 0.11036, respectively, are three essential indicators in explaining urban morphology.
