Monitoring of Vegetation Changes by Using NDVI Index Using Landsat during the Years 2000-2009: a Case Study

摘要

Evaluating vegetation changes in every area is very important because if the monitoring of vegetation changes over time in each area be examined, changes of human pressure and environment would characterize. Thus, proper planning can be done to preserve the life of a region. Today for the vegetation evaluating the remote sensing and different indicators are used; NDVI is one of the most important indices in this field. In order to assess the vegetation of Eskandari watershed area in Isfahan province the Land sat TM sensor images were used. The vegetation of this area was prepared by NDVI index for the years 2000 and 2009. The results of this study showed that the vegetation in this area has increased. The changes of the urban areas are also notable. It is necessary that experts pay attention to the area in order to prevent damage to the vegetation due to the suitable climatic conditions that prevailed in the region in recent years.
