Spatial and temporal analysis of land use changes using remote sensing in Sari city

The increasing population growth and subsequent horizontal expansion of cities has led to land use changes, especially in Mazandaran province, which has led to an increase in land prices and the destruction of urban ecosystems. The conversion of horticultural and paddy lands into residential areas, which have shown increasing growth in Mazandaran over the past few decades, can be an important factor in exacerbating urban flooding. As a result of the destruction of vegetation, we see consequences such as urban floods. In addition, land use change is one of the major challenges in the future and seems to affect many vital chains and regional security. The study used data from a 30-year period of Landsat satellites from 1978, 2001 and 2013 in and around Sari. Using the GIS environment from the LCM model, land change forecasts were made until 2018. In this regard, out of three scenarios of A-B-C and for each of the six variables and 10 maps, the potential for transfer prediction of changes was performed. The capa coefficient and the overall accuracy of the maps for 1987 have been calculated as 88%, 86.87%, for 2001, 89% and 87.22%, respectively, and for 2011, this coefficient has been calculated as 90% and 88.89%. The results show that the level of agricultural lands is declining sharply and the occupation of residential lands is increasing
