Abstract

Background and Objective: Study of resources changes and destruction in previous can be useful in the planning and optimal use of resources to control inappropriate changes. Because of land use changes occur on large-scale, Remote Sensing techniques is a useful and valuable tool for monitoring the changes. The aim of this research is to monitoring of Land Cover Changes in Khojin Watershed located in the south of Ardabil province using Remote Sensing technique. Method: First TM, ETM+ and OLI images for the year 1986, 2001 and 2016 were collected respectively and after geometric and elevation corrections, images were classified using maximum likelihood classification method. To increase classification accuracy, NDVI, elevation and slope percent layers were used. Kappa and overall accuracy indexes were used to calculate classified images accuracy. Findings: Based on results, in the first period (1986-2001) 22. 36%, in the second period (2001-2016) 20. 73% and in the third period (1986-2016) 28. 08% of area has changed and in all 3 periods, changing from rangeland to dry farming reached the most change. Discoution and Conclusion: Results showed despite high capability of Landsat images in mapping land use, using additional layers like NDVI, elevation and slope percent can improve classification accuracy of classified images.
