| Abstract: |
| Monitoring and evaluation of vegetation drought stress is an important component of risk management and crisis management in drought conditions. In this research, vegetation condition index (VCI) was used to evaluate the vegetation cover of Qazvin basin. First, using the MOD13Q1 from Modis satellite, NDVI was extracted from 2001 to 2017 for the months of April to July. The vegetation cover of the plant is in its best condition in this plain in these months. Then, the monthly average of NDVI was taken for each year. Using the monthly average of NDVI the VCI Index was calculated for each year. Finally, the mean and standard deviation of this index were evaluated in different land uses. The results showed that vegetation has the worst condition in 2001 and 2015 with the lowest average of VCI, and in 2012 and 2016, vegetation has the best condition with the highest average of VCI. The use of garden lands is the most stable land uses, with the highest average and one of the least standard deviations of the VCI. In bare land, dry land and poor rangelands, there are the most unsuitable conditions for vegetation, with the lowest mean and maximum standard deviation of the VCI. |
