本文应用灰色系统理论,对阜平县历年大枣产量进行灰色预测分析,建立了阜平县大枣产量的拓扑预测模型,并对1986～2000年的大枣产量作了预测,初步找到了其产量的未来变化趋势。通过与1986、1987年实际产量相比较,证明此模型是可信的。总之,作为一种分析方法,灰色预测在林业生产预测中的确是可行的。 In this paper, the gray system theory was applied to forecast the jujube yield in Fuping County over the years. The topological prediction model of the jujube yield in Fuping County was established. The yield of jujube in 1986 ~ 2000 was predicted. Future trends in output. By comparing with the actual output in 1986 and 1987, this model is proved to be credible. In short, as a method of analysis, gray prediction is indeed feasible in forestry production forecasting.
