abstract

today, human development and greater mastery over the environment has caused environmental changes occur faster and wider

than before. thus having information about these changes is essential for management and restoration of ecosystem`s sustainable

normal order. landscape metrics are quantitative tools of landscape situation. these metrics can give us a lot of information about

the structure and changes of landscape components. this study has been performed to investigate the landscape changes in

golpayegan city located in isfahan province in central iran. in order to preparation of land cover maps and change analysis, satellite

imagery 1972 (tm) and 2010 (etm +) and class area, patch density, number of patches, mean patch size, edge density and mean

shape index metrics were used. for analysis of landscape fragmentation, various metrics of landscape pattern in class level were

calculated using the fragstats software. landscape metrics analysis shows that medium ranges have been replaced by agricultural

lands, poor ranges, residential lands and bare lands. according to the results, increasing in the number of patches and decreasing

in the area average are important indicators of decomposition that indicate the destruction and fragmentation of the landscape. the

results of this study can be used in land evaluation, environmental studies and planning and integrated management for rational

utilization of natural resources and reducing of resource degradation.

key words: environment; fragstats software; indicators; kappa coefficient; patches; satellite imagery.
