摘    要:需水量是城市水资源的一个重要方面,预测城市居民需水量成为指导水资源合理配置的最重要的一项科技指标。本文以吉林省白城市2004~2013年的居民需水量数据为研究对象,比较不同维数的灰色GM(1,1)预测模型的误差,选择最优模型对白城市今后五年需水量进行预测分析,可以为水利部门分配水资源提供科学依据。

关 键 词:需水量  灰色预测  数学模型

Abstract:Water requirement is an important aspect of urban water resources, predicting urban water demand as the guidance of the rational allocation of water resources one of the most important technology index. Taking Baicheng city of Jilin province in 2004-2013 data as the research object, the water requirement to compare different dimension of gray GM(1, 1) prediction model error, select the optimal model of urban water demand forecast in the next five years dialogue analysis, can provide a scientific basis for allocation of water resources for water conservancy department.
Keywords:water demand  grey prediction  mathematical model
