摘要
采用仿真技术和时间序列分析方法,建立了粮食产量参数化预报模型,并对模型的精度进行了检验,经4年的应用,预报的粮食产量的平均准确率为96.6%.
In this paper,the parameterized prediction models of grain output were established by using imitation technique and time series analysis,and their precisions were tested.Through four years'application,the degree of accuracy of the predictor is about 96.6%.
