Abstract

The present study was designed to evaluate the trend and pattern of changes in urban growth in KARAJ CITY over the years 1989-2013 applying the LANDSCAPE SYNOPTIC ANALYSIS approach. Accordingly, LANDSCAPE maps of three frames of the satellite image of the TM sensor of Landsat taken in 1989, 2001 and 2013 were prepared using the post-classification comparison method. Then some composition and configuration-based metrics including number of patches, patch density, percentage of LANDSCAPE, largest patch index, LANDSCAPE shape index, edge density, contagion, and shannon’s diversity were calculated at two class and LANDSCAPE levels, and their changes were examined. The data collection methods were the use of library resources, satellite imagery, topographic maps, and field visits to the region. The results of SYNOPTIC ANALYSIS indicated that although the LANDSCAPE of the city during the first period (1989-2001) has experienced a different change trend compared with the second period (2001-2013), generally, the LANDSCAPE of the region under study has become more fragmented (the number of patches have increased from 1612 in 1989 to 2024 in 2013), more complex and irregular in shape, more disconnected in continuity of patches, and less diversified in terms of land use/land cover types at the end of the 24-year period. The results also revealed that the spread of man-made areas has caused an increase in fragmentation, irregularity and complexity of patches, and a decrease in the total area of agriculture class of the region; if this process continues to exist, it may result in a serious decrease in the uses and services of the ecosystems, especially in agricultural use.
