Application Of Extreme Value Analysis To Extreme Drought Disaster Area In China

Recently, the natural balance and harmony of human society has been broken by the frequent occurrence of extreme drought. Extreme value theory is a statistical analysis tool of extreme events on the risk management which provides a good support of theoretical and methodological application. In this paper, we analyze the data of drought disaster losses area from 1949 to 2008 years in China, and establish a G model of extreme value distribution, and then verify the application of extreme value theory can significantly improve the fitting results.
