Abstract：Aiming at the problem of long-term evolution law of the time series with the seasonal frequency characteristic, this paper adopted the grading method based on contour analysis and clustering analysis, divided the factor contour similarity sequence into spring drought wet year, spring pianku flat water years, winter drought dry years, winter pianku level annual, and summer pianku partial harvest year 6 states, and established the annual rainfall state transfer model based on Markov chain and transition probability matrix theory. The period of each state was estimated by the stationary distribution. The experimental results show that the region in spring pianku flat water years and winter pianku water level of probability is relatively large.
