【Abstract】 This paper firstly investigated the current situation of grain production in Hubei province,then specifically analyzed the fluctuations of grain output from 1989 to 2009.According to the Hubei food output statistics and survey in the recent 20 years,the wave theory was applied to the changes in food production,also fluctuation coefficient,volatility cycle and other indicators were used to study the fluctuation circle and character.The impacting factors of grain output were analyzed and proposals were made to ensure food security incorporating with the population change in Hubei province.更多还原
