摘要
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.
