Abstract

Land use reflects the interactive characteristics of humans and the environment and describes how human exploitation works for one or more targets on the ground. Land use is usually defined on the basis of human use of the land, with an emphasis on the functional role of land in economic activities. In this research, a pixel-based method and Object-Oriented method for mapping the map of Maragheh city using ASTER sensor images in a 17-year time series were compared between 2000 and 2017. Also the effect of land use changes on erosion was studied. In order to compare the results, both methods used the same educational data for classification. Then, the most important methods for assessing accuracy including precision and kappa coefficient of classification were extracted, and it was determined that the result of the Object-Oriented classification was better than the 3% Offers. The increase in accuracy in a method based on Object-Oriented classification largely depends on choosing the appropriate parameters for classification, defining the rules, and applying the appropriate algorithm to obtain the degree of membership. After classifying and comparing the extracted maps, we attempted to reveal the changes that occurred during this period and it was determined, that the rangeland and Bayer classes have a decreasing trend and dense garden classes and water with increasing trend. According to the user-mapped maps of the two methods of maximum-likeness and Object-Oriented classification and comparison and adaptation of these maps with ground-based properties, the results of the Object-Oriented classification method were confirmed. According to the results of the study, with Object-Oriented method, in the Maragheh area, densely populated gardens, gardens, housing, housing, agriculture, industry, and communication in the Object-Oriented method have increased, and agronomic, pasture, dryland and Bayer uses Reduced area. This indicates the importance of agriculture and horticulture in this city. In 2000, 9. 08 percent and 15. 88 percent of study area are located in very high-risk and high-risk erodibility and these values for 2017 are 13. 66 and 29. 76 percent respectively. Also results showed that dense and low dense agricultural land, residential and industrial land use have been increased.
