摘要
建立了两个能拟合、预测可持续增长过程的曲线模型，讨论了曲线模型的若干性质，给出了模型参数估计的非线性规划方法，通过两个实例的验证说明了模型拟合效果好，预测精度高．
In this paper, two curve models are proposed to fit and forecast sustainable growth. Their propeties are also discussed and the related nolinear programming algorithms are developed for estimating the parameters. The two models are verified in fitting and forecasting the average per unit yield rice output in Fujian and the total food output in China as well.
