- Abstract:
- With the climate warming, drought is becoming more and more common. The study on the drought has been a hotspot for decades worldwide. The temperature and vegetation dryness index was calculated using the MODIS products to evaluate the temporal and spatial characteristics of drought in the Xilingol grassland from 2002 to 2016. The results showed that the Xilingol grassland was in drought at all phases, but mainly in light drought and moderate drought with less severe drought; temporally, the large-scale of moderate drought was prone to occur in June, August and September; the light drought occurred widely in July and the first half of October; spatially, the light drought mainly occurred in the western area, while large scale of moderate drought and regional severe drought were found in the middle of east and southern part of the study area. Different levels of drought were also occurred in the central and northern Xilingol, where severe drought was frequent.
