@ARTICLE{Maleki, author = {Mir, M. and Maleki, S. and Rahdari, V. and }, title = {Application of Landscape Ecology in Spatio-Temporal Change Detection of Arid Regions, Case Study: Sistan Plain}, volume = {10}, number = {2}, abstract ={Population growth followed by increasing human needs has caused widespread environmental changes in various ecosystems. Change detection is necessary to properly manage the ecosystem and protect the structure and functions of ecosystems. Landscape ecology provides concepts, theories, and methods for assessing and managing lands. In the current study landscape metrics were used to assess spatio-temporal changes in the Sistan Plain. Landscape metrics were created at class and landscape levels. These indices were calculated, using land use/cover maps of 1977, 2000, 2015, and 2021. Results showed that at the class level, the highest number of patches and fragmentation of the vegetation cover was occured in 2000 and the lowest number of vegetation patches was in 1977. With the inflow of water from Helmand and Farahrood rivers in 2015 and 2021, the vegetation cover, comprising a variety of Tamarix sp, Aeluropus sp, and Phragmites sp, has increased. Due to the inundation of Hamoun and Farah rood rivers, the water and vegetation cover has fewer patches with more connectivity. The highest number of patches in the water body class was in 2015, due to the limited inflow from the Hamoun wetland and the lowest number of water body patches was observed in 1977. This study shows that landscape metrics can determine changes in arid ecosystems. Also, these metrics can quantify the changes in ecosystems and be used in ecosystem management of arid lands. }, URL = {http://ijae.iut.ac.ir/article-1-1050-en.html}, eprint = {http://ijae.iut.ac.ir/article-1-1050-en.pdf}, journal = {Iranian Journal of Applied Ecology}, doi = {10.47176/ijae.10.2.13271}, year = {2021} }
