Preliminary Study on Gray Theory in Forecasting Great Drought in Shaoyang District

By using occurrence years of great drought in Shaoyang district in recent 20 years,the time sequence was established,and by gray disaster prediction theory,the possible great drought years in future in Shaoyang district were predicted. The results showed that one quasi-periodic of great drought occurrence in Shaoyang district is 2 years,the next great drought years are 2010,2012 and 2015. Gray prediction drought theory will provide scientific basis for drought resistance work in Shaoyang district.
