In the developing countries, habitat loss and fragmentation severely affect protected area, due to the rapid expansion of anthropogenic activities that has occurred in the last decades. Landscape metrics are commonly used to define landscape patterns and to evaluate fragmentation processes. In this study, remote sensing data and landscape metrics are used to investigate the changes in land use and landscape pattern in Sorkhe Hesar national park, Iran over a study period from 1986-2010. Landsat Thematic Mapper (TM) images are processed using ENVI and landscape metrics are calculated at landscape and class levels using FRAGSTATS. Landscape metrics analysis shows that land use patterns in Sorkhe Hesar have been undergoing rapid changes over the past 25 years. Changes were mostly due to the conversion of poor range and orchard to urban built up area which in 2010 had increased by more than 18.9 times in 1986. An evaluation of landscape pattern based on landscape metrics analysis indicates rapid urbanization from 1986-2010. Due to rapid economic development and urbanization, the landscape became more fragmented from 1986-2010. The study demonstrates that landscape metrics can be a useful indicator in land use change analysis and are vital for integrated landscape evaluation.
