Investigation of Land Cover Changes in Lenjanat Using Satellite Images During 2001 to 2016

Revealing all kinds of land cover changes, as the basic information for different planning, is of particular importance and is one of the most important needs in managing and evaluating natural resources. Because land use changes are widespread and extensive, remote sensing technology and the use of satellite imagery are an indispensable tool for assessing the extent and extent of land cover changes. This study was conducted to investigate land cover changes in the Lenjanat area, which includes Zayandehrud margin lands in three cities of Lenjan, Mobarakeh and Falavarjan in Isfahan during the last 15 years. In this study, landslide maps were prepared using Landsat Screenshots in 2001 and 2016, and using the Supervised classification method for maximum probability. Then, using the comparison method after the classification, the changes were made. Comparison of land use maps has shown that the level of coverage of the region, including agriculture and urban green space, has decreased. While the urban land surface reached 214.22 hectares in 2001 to 32148 hectares in 2016. During this period, about 13978
hectars (about 6.76) of vegetation were changed to urban lands. Thus, in the past 15 years, a significant part of the agricultural population has turned into residential and industrial areas around Zayanderroud's margin.
