引水量的预测对于水利调度至关重要,基于时间序列法的原理,建立了线性预测模型和二次曲线预测模型,对依干其水库的引水量进行预测,预测结果与实际值大致相当,证明了预测模型的可用性。通过所建立的预测模型,采用考虑近期数据和历史数据两种方法对依干其水库2017年的引水量进行预测,得到了两种不同视角的预测结果,最终通过取平均值的方法,确定了依干其水库2017引水量的预测值。 Prediction of water diversion is very important for water conservancy regulation. Based on the principle of time series method, a linear prediction model and a quadratic curve prediction model are established to predict the water diversion of the reservoir. The prediction results are approximately the same as the actual values, Predictive model availability. Through predicting the water diversion in 2017 according to the forecasting model and adopting both recent data and historical data, the forecast results of two different perspectives are obtained. Finally, by means of averaging, According to dry its reservoir in 2017 forecast the value of water.
