摘要
通过对1994～2004年辽宁省农机总动力历史数据的统计分析,建立了农机总动力发展的组合预测模型,并对农机总动力进行了预测。预测结果表明,组合预测模型优于单一预测模型,使预测精度有了一定的提高,用其对辽宁省农机总动力进行预测更具有合理性。分析预测结果对辽宁省农机发展规划有着重要意义。
Based on statistical analysis of historical date of total power of agricultural machinery from 1994 to 2004 in Liaoning Province, a combination prediction model for predicting total power of agricultural machinery was developed. The result of prediction showed that the combination prediction model was superior to a single prediction model with higher predicting accuracy. The results of the study had significant impact on development planning of agricultural machinery in Liaoning province.
