In this study, the Marquardt method (Yuan and Sun, 1997) which can solve known nonlinear function estimation problem effectively is applied and a predictive analysis is built based on the analysis of the nonlinear relationship cases between China's grain production statistical data of population, production and consumption from 1978 to 2010 and through the example to show that the method is practical and feasible with high curve fitting degree.
