The results showed that the maize yield in Jilin Province increased in unstable fluctuation, with high-frequency fluctuation cycle and irregular length.The amplitude of fluctuation is severe. From four aspects, namely natural disaster, agricultural policy, maize market,science and technology, the factors of fluctuation of maize yield in Jilin Province was analyzed. Measures of preventing and arresting super-long fluctuation of maize yield were put forward.
