本文根据气候演变规律、采用综合距平相关法、统计分辨法和分级多元回归方法建立了甜菜产量的长中短期预测模式.含糖率预测,则直接建立长中短期多元回归预测模式、长中短期预测模式可以互为补充订正,有效地克服了运用单一模式常因气候突变而出现预测失误的不足。其预测精度较高。 In this paper, based on the law of climate evolution, a comprehensive long-term and short-term forecasting model of sugarbeet yield is established by using the method of integrated anomaly correlation, statistical resolution and stepwise multiple regression.With the prediction of sugar content, the long- Short-term forecasting models can complement each other and effectively overcome the shortcomings of forecasting mistakes often caused by sudden changes in climate using a single model. Its prediction accuracy is high.
