Abstract

Nowadays, the expansion of human societies and greater environmental dominance have caused more rapid and wider environmental changes to take place. This will reduce the scope of the natural arenas and increase its dispersion and termination. The aim of this research is to evaluate the time variation and spatial distribution of the Piranshahr land plots with the help of remote sensing and land surveying in a ten-year time horizon, which is important for current and future planning of land use for sustainable development. Landsat satellite images were used to prepare land use map. In order to investigate land use changes during this time interval, Fragstats software was used to measure the Number of Patches, Patch density, percentage of Lands, Largest Patch Index metrics in the class level, and the number of patches, patch density, Shannon,s diversity and contagion metrics in landscape level. The results of the research using the metrics at two levels indicate that, in general, the shape of the fragmented landscape is more complex, irregular, and in terms of the integrity of the structural elements, the more discontinuous (from 39.01 to 33.06%) and in terms of type The use of coverage in a more diverse area (from 1.04 to 1.15) has been used.
