Investigation Of Vegetation Cover And Its Distribution Around Salt Lake Of Sirjan And Changes In Vegetation On Agricultural Lands
Using the characteristics of satellite data, monitoring, evaluating, and controlling actions that affect the environment in some way can be achieved and even predicted quickly and accurately. This study aimed to investigate the vegetation cover and its distribution around the Salt Lake of Sirjan and changes in vegetation on agricultural lands. The salt pan of Sirjan (salt pan of Khairabad) with an average height of 1688 meters above sea level in geographical position between 29°10'N to 29°41'N and 55°20'E to 55°31'E is located in the west of the Sirjan city. In this study, using remote sensing data, as well as using the NDVI plant index on two series of satellite data of 2002, 2008, and 2013, the type and amount of vegetation were studied and their changes and expansion. The research technique was to use correlational and comparative methods. This study sought to examine changes in vegetation for over 15 years. In this regard, ASTER satellite images were examined over 15 years at intervals of 5 years. The results showed that the density of vegetation and its distribution around the salt lake is changing, and there was no relationship between changes in agricultural lands and changes in the level of Salt Lake of Sirjan.
