Abstract :
The explosion of the population and the development of cities in the last century have caused many problems, including the destruction of agricultural lands and green spaces, which is the subject of our discussion in this study. The city of Kerman has seen rapid growth in recent years in the city's physical development, with its direct reflection of the loss of green spaces in and around the city. With the help of Landsat images and comparison of land use maps, it is clear that this trend has been rising rapidly between 2000 and 2018. In this research, data gathering was done through field observations and use of Landsat satellite imagery. ENVI, ArcGIS and Google Earth softwares have been used for statistical and visual analyzes. On satellite images in the ENVI software, radiometric correction was performed using Radiometric Calibration, and then by FLAASH Atmospheric Correction, an atmospheric correction was performed to minimize the error. The results show that over the years, almost 11% have been reduced from the share of agricultural lands and wastelands and by contrast, the share of land that has been built has increased the same amount. Therefore, it is possible to make suggestions including the use of infill development for the conservation of agricultural lands, the completion of the green belt of Kerman city by the municipality, construction on the arid lands in the 2nd district of Kerman, preventing land speculation, and fully comply with the rules of comprehensive and detailed plans, especially on urban green spaces.
