     Human activities often leave inconsistent impacts on land landscapes and ecosystems. The current research was conducted to investigate the changes in land use based on analyzing the land landscape plot metrics using remote sensing and GIS in Miandoab city.  For this purpose, spot and sentinel images with 10-cm resolution were prepared for the years 2005 and 2017. Then, images were classified after performing pre-processing and radiometric corrections in the ENVI 5.1 software, using artificial neural network algorithm. It should be noted 7 classes, including water zones, salt marsh, rangelands, garden lands, agriculture lands, arid lands, and human-made lands) were extracted using this algorithm.  Finally, after verifying the results, the changes were calculated and land surface land landscape metrics were calculated to quantify structural changes using the FRAGSTAT software.  The results analysis indicated that human-made lands (28.77 km2), garden lands (143.61 km2), salt marsh (2.53 km2) increased in the study area and other land uses decreased. CA metric also shows the same changes. Metric investigation of number of spots also showed that the current land uses in this city is unstable, so that garden lands increased from 1611 spots in 2005 to 4912 spots in 2017, and other land uses showed the similar increase. By comparing and examining the results and metrics obtained, it could be stated that land landscape structure in Miandoab in the current situation is in the disturbance situation due to the destruction and inappropriate use of resources, indicating the destruction development process in this area. This research results emphasize on the need to pay more attention to the sustainable exploitation of the land and prevent its destruction in this city.
