中文摘要:

      以2005—2014年10年间我国居民生活用水资料为依据，应用灰色理论构建等维递补动态GM(1,1)模型，对我国居民生活用水进行预测。统计检验和误差分析结果表明，该模型预测精度高，可靠性强，结果符合实际，为制定城市居民生活用水标准和水价提供了科学依据。

英文摘要:

      Based on the data of our country domestic water consumption in 2005-2014 years, forecast of our country domestic water consumption was done by the equidimensional filling vacancies dynamic GM(1,1) model with the grey theory. Statistical test and error analysis results showed that the model prediction accuracy was high, the result accorded with actual, reliability, and scientific basis was provided to make the standard of the urban residents domestic water and water price.
