Annual Spatial Distribution Data for Drought Monitoring in Mongolian Plateau (1981-2012)

The vegetation degradation, drought and other environmental issues in the Mongolian Plateau have been as the hot spot in the study of the climate change and the ecological environment changes in Northeast Asia. However, it is lack of study focused on building the stable drought monitoring model and their spatio-temporal differences between Mongolia and Inner Mongolia. Based on the NOAA AVHRR NDVI-PathFinder 10d remote sensing data of 1981-1999 and MODIS vegetation index and the surface temperature 16d data of 2000-2012, the knowledge service inverted Temperature and Drought Vegetation Index (TVDI) by the Ts-NDVI general space, their spatio-temporal distribution and changes were studied. The main conclusions are as follows: The inverted TVDI based on NOAA AVHRR NDVI-PathFinder and MODIS data, could explain the macro spatio-temporal distribution and changes of drought. The vegetation cover and drought in the Mongolian Plateau has obvious zonal distribution, and closely related with the Land Use/Land cover types. Drought is common in the Mongolian Plateau, and it is severe drought in some years. There were differences between the changes of TVDI in different regions of different Land Use/Land Cover.

  •   Wulanchabu , Inner Mongolia suffered from drought, and nearly 388,000 people had difficulty drinking water.
  •   Some parts of Inner Mongolia have been hit by severe drought and 1.02 million people are in need of living aid
