摘要
本文简要介绍了当前较为流行的一种新的预测方法—组合预测方法及最优权数的计算。并利用此方法对预测土壤水分含量的两个单一预测模型进行综合处理，得到了土壤水分含量的组合预测模型，从统计分析和回归检验中可以看出，组合预测模型较原两个单一预测模型的预测精度有较大的提高。
In the paper , the new forecasting method --the combination forecasting and optimum weight number were introduced, and the new method was applaced toforecasting soil moisture , and established the combination forecasting model of soil moisture Statistical analysis and backword test showed: the forecasting precision of the combination forecasting model was better in other two models
