| 摘 要： | 基于年需水量原始时间序列具有非线性随机变化的特点，而一次累加法具有削弱时间序列随机性、增加时间序列规律性、便于回归函数拟合的特点，该文提出了一次累加回归分析法在城市年需水量预测中的应用。实例表明，一次累加建模方法具有精度高，预测结果可靠，可用于城市年需水量预测。

| Abstract: | Because of the city's annual water consumption forecasting time-series has the characteristics of randomness,and one-accumulate methods has the characteristics of smoothing time-series randomness,improving rule ness and it's easy for regressing.Basis on this,this paper puts forward one-accumulate forecasting methods applies in the forecasting of city gas load.Practical example indicated that this method has the higher accuracy and steady,and it can used for this city's annual water consumption forecast. |

| Keywords: | one-accumulate city's annual water consumption forecast variety polynomial |
