应用灰色理论建立了GM(1,1)模型,对合肥市年用水量进行了预测.对所建模型进行了残差检验、关联度检验、均方差检验和小误差概率检验,精度均满足要求,可以用来预测城市用水量.结合可利用水资源现状,分析了合肥市水资源量的保证程度.结果表明:在未来26年左右,合肥市的用水量将超出水资源供给能力,可能会出现严重的水危机,如果不加以控制,人们的生活生产将会受到影响.提出了城市化过程中水资源合理利用的有益思路.
應用灰色理論建立瞭GM(1,1)模型,對閤肥市年用水量進行瞭預測.對所建模型進行瞭殘差檢驗、關聯度檢驗、均方差檢驗和小誤差概率檢驗,精度均滿足要求,可以用來預測城市用水量.結閤可利用水資源現狀,分析瞭閤肥市水資源量的保證程度.結果錶明:在未來26年左右,閤肥市的用水量將超齣水資源供給能力,可能會齣現嚴重的水危機,如果不加以控製,人們的生活生產將會受到影響.提齣瞭城市化過程中水資源閤理利用的有益思路.

Based on the theory of grey system, this paper establishes GM (1, 1) model for forecasting the water consumption of Hefei. The check-up model residual error text, relational coefficient text, variance text,little probability of error text and the precision of the model are well enough to meet the requirement and prove the feasibility and adaptable of the method. So it can be used to predict urban water demand. Availability of water resources in the status,and the assurance level of water resources in Hefei are analyzed. The result shows that the total water consumption in Hefei will grow unceasingly. Combined with the water supply capability of the city in recent years, the water consumption calculated is more than its supply in the next 26 years. Suggestion is presented for the protection and reasonable using of water resources during the urbanization.
