摘要
以2005—2014年的10年间我国农业灌溉用水资料为依据,应用灰色理论构建等维递补动态GM(1,1)模型对我国农业灌溉用水进行预测.统计检验和误差分析结果表明,该模型预测精度高,结果符合实际,可靠性强,为制定农业灌溉用水标准和水价提供了科学依据.
From 2005 to 2014 10 years of agricultural irrigation water in China based on the application of grey theory to build dynamic equal dimension GM (1,1) model to predict the agricultural irrigation water in China. The results of statistical tests and error analysis show that the model has high prediction accuracy, and the results are consistent with the actual situation, and the reliability is very strong.
