Abstract:
Based on the risk theory, drought hazard, drought exposure and drought vulnerability were evaluated by precipitation, water consumption and water supply, respectively. A model of drought risk assessment method was thus proposed and it is finally applied in China. The results showed that the drought hazard index in the eastern monsoon region was higher, the drought exposure index in the Yangtze River Economic Belt, north China Plain, Heilongjiang Province, Inner Mongolia Autonomous Region and Xinjiang Autonomous Region was higher, the drought vulnerability in the southern region is higher. The middle and lower reaches of the Yangtze River, north China Plain, southwest China, Heilongjiang province in northeast China and Xinjiang Autonomous Region in northwest China are at high risk of drought.
