Prices of agricultural products are influenced by many factors including the climate, the level of household consumption, consumption structure, the structure of supply and demand of domestic and international stock and futures markets and the circulation system of agricultural products, have a nonlinear dynamic system characteristics and the evolution law, suitable for the application of chaotic time sequence to study the law of price fluctuations and price forecasts. In this paper, we mainly use the chaotic time series theory and methods to study the law of the price fluctuations of agricultural products in China, in theory it can explore new ways for fluctuation research in prices of agricultural products and in practice it can provide a scientific basis for the planning of agricultural production.
