Investigating the effect of climatic changes and human activities on vegetation cover in Zayandeh Rood Basin

Water crisis and scarcity, have been one of the most important issues in the Zayandehrud basin in recent years. In the past decade, by changing the management of the basin from integrated management of the basin to provincial management, the drainage crisis and the destruction of resources have become more intense in changing the use of agricultural land in the west of the basin. Therefore, this study has been conducted to determine the trend and type of land use and to study the effects of climate change and human intervention in this basin.
In this research, satellite mapsfrom Lansat 8 and 5 have been used for this purpose. Atmospheric and radiometric correction were done. Using the NDVI vegetation index, the distribution of land types during the period from 1993 to 2015 is set to for 4 classes.
The results of the study of land cover and natural ecosystems in Zayandeh Rood basin during the past 23 years have shown that in the period of ten years after the implementation of provincial management, agricultural lands and natural ecosystems with trend An increase is going to be destroyed because of developing of agricultural lands and roads in this area.
The results of this research will make it possible to make basic decisions in developing management policies for planners and managers in the Zayandehrud basin for sustainability and assessment of natural resources.
