摘要：The present research aims to investigate the geomorphological changes of the city lands due to the physical development of Shiraz during the years 1967-2018.Therefore,to find out the type and amount of changes in this area,images of Landsat sensor+MSS,TM,ETM,for years(1976,1986,1996,2006,and 2018),and aerial photographs of Shiraz at a scale of 1:20,000 in 1967,as well as the map and statistics of the demographic changes of the city during the above years have been analyzed.Envi4.8 and ArcGis10.3 software have been used to process and interpret satellite imagery and to provide intended maps.First,the land cover and land use for Shiraz metropolis and its surroundings were derived and the changes of agricultural and barren lands to urban use were identified using the changes detection by post-classification comparison images technique.The results of this research show that during the 50 years of study,the area of this metropolis and its population was increased around 12 and 6 times respectively.These changes were mainly due to human activities,including the effects of urban development on the landforms and lands around the Shiraz,such as changes in the steep slopes of the mountains and the canals(from the north),expansion of the city on loose formations with low strength(from northwest and west),development of the city in the areas where groundwater levels are high and also the flood plain(from south and east).
