摘要
文章针对粮食年单产量是相依随机变量的特点,采取以规范化的各阶自相关系数为权重,以16年(1991-2006)的统计资料为实例,用加权的马尔柯夫链模型预测和分析了我国未来粮食生产的丰欠年景。
Annual grain yield per unit is of random variable characteristic depend on deeply, in view of which the standardized steps autocorrelation coefficient has been adopted as the weight, as well as 16- year -statistical data(1991-2006) as the example. This paper forecasts and analyzes whether the grain production of our country is abundant or not in the future with the weighting Maerkefu chain model.
