The vegetation degradation, drought and other environmental issues
in the Mongolian Plateau have been as the hot spot under the background
of climate and ecological environment changes in Northeast Asia. The
Disaster Risk Reduction Knowledge Service System developed the application
of Annual Spatial Distribution Data Service for Drought Monitoring in
Mongolian Plateau (1981-2012).
The Mongolian Plateau (88°43 ' E - 126°04' E, 37°24 'N - 53°23' N)
is an important geomorphic tectonic unit of Eurasian hinterland. The
Mongolian high pressure has an impact on the climate of East Asia, makes
the ecological environment fragile and sensitive.
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 the extraction information of vegetation
cover changes, building the stable drought monitoring model and their
spatio-temporal differences between Mongolia and Inner Mongolia.
Researchers utilize NOAA AVHRR NDVI-Path Finder 10d remote sensing data
of 1981-1999, and MODIS vegetation index and the surface temperature 16d
data of 2000-2012, based on Ts-NDVI a stable drought monitoring model is
constructed in the general feature space, based on the temperature
vegetation drought index, visualized the spatial and temporal distribution
characteristics of drought in the Mongolian Plateau; On this basis, it is
convenient for researchers to analyze the spatial and temporal differences
of the drought evolution in the Mongolia Plateau.
Therefore, the Disaster Risk Reduction Knowledge Service System developed
the application of annual spatial distribution data service for drought
monitoring in Mongolia Plateau (1981-2012).
