Abstract

Under the background of global warming, drought is one of the main meteorological disasters in China. The risk assessment of drought disaster is the premise of risk early warning and actual disaster evaluation, and it is the basis of disaster prevention and reduction. In this paper,meteorological data, remote sensing data, soil moisture data and basic geographic information data were used to extract the environmental sensitivity assessment factors of the grassland drought disaster. According to the analytic hierarchy process and the expert evaluation method, the weight of each index was determined. The linear weighted comprehensive method and the system clustering method were used to analyzeand zone the spatiotemporal characteristics of environmental sensitivity of drought disaster in Xilingol Grassland.
