Abstract

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).
