摘要
随着我国经济的发展,城市化进程不断加快,城市水资源的供应和需求之间的矛盾不断加深。本文依据成都市供水量季度数据序列,根据刻画时间序列的自相关和偏自相关函数来最终确定ARIMA模型的具体形式,建立合适的模型来对成都市供水量做出预测。结果表明:拟合的模型参数是合适的,而且ARIMA模型对短期预测相当有效。
The conflict between urban water supply and demand is deepening with China's economic development and the urbanization process accelerating.Based on the water supply quarterly data series of Chengdu,according to characterization time series autocorrelation and partial autocorrelation function to determine the ARIMA final concrete form,this paper established the appropriate models to forecast water supply in Chengdu.The results show that the model parameter of fitting is appropriate and ARIMA model is quite effective in short-term forecast.
