Abstract
Chaharbagh city is located in the west of Alborz province. This area has been considered the agricultural and horticultural center of the region since the distant past. But in recent years, it has changed its usage drastically. The purpose of this research is to investigate the amount of land use changes in this city, to investigate the factors affecting it, to prioritize these factors and to examine the legal challenges of land use change. This research has been done in four stages. In the first stage, in order to evaluate the temporal and spatial changes of land use in four gardens of Karaj, satellite data of the years 1992 and 2022 of the Landsat satellite were prepared. Then the land use map was prepared from this data in ENVIE 5.1 software. Then the raster data will be transferred to the TerrSat software environment to determine the amount of land use changes. The results showed that the intensity of changes in the time period from 2002 to 2012 was more than in other time periods and the use of human centers was facing positive growth more than other uses. While the uses of agricultural and garden lands and pastures have been facing negative growth. Most of the changes have occurred geographically in the eastern and northern parts of the region, which are adjacent to Karaj. Finally, the results showed that there is a special importance of maintaining land use according to the specific law in most parts of the world, this issue has been neglected by Iranian legislators for many years, and even after the first steps in the direction of maintaining and continuing land use and preventing its change was removed.
