Abstract :

Abstract In urban areas, population growth has changed the use of agricultural lands to residential, commercial and industrial. These changes have unpleasant consequences for the urban environment, such as reduced vegetation and increased ambient temperature. Therefore, evaluating the effects of land use change for proper management in urban areas seems necessary. Therefore, the purpose of this study is to investigate the factors affecting the development of Babak city with regard to the category of sustainable urban spatial development from an ecological perspective. For this purpose, using Landsat 2, 7 and 8 multi-time satellite images and object-oriented satellite image processing techniques, land use changes in the period 2021-1997 with emphasis on the spatial expansion of Babak city have been evaluated. For this purpose, the factors affecting the physical development of Babak city were identified based on the research background in the form of 17 indicators and mapped using multivariate evaluation methods based on CLW fuzzy weighted linear combination and by extracting lands prone to future physical development During the years 2021-1997, using the Markov chain automated cell model, the future land use pattern was predicted in the form of an environmental protection approach and in accordance with the principles of sustainable development until 2065. If the results of this study are used, in Future developments of the city will cause the least damage to pasture and green lands
