弹性系数法是一种广泛使用的需水量预测方法,其建立模型的关键步骤是提取合理的需水量影响因素.为了有效地提取需水量的主要影响因素,采用灰色关联法,分析了弹性系数模型变量之间的关系.提出了自然对数预处理方法,并以郑州市生活需水量预测为例,进行方法的比较分析.结果表明该方法是合理和有效的.进一步丰富了灰色关联分析法的应用.需水量预测结果也比较符合实际情况,可为郑州市水资源规划提供参考依据.

The elastic coefficient method is a widely used water demand prediction method, and the key step of modeling is to extract reasonable water demand influencing factors. In order to effectively extract the main influencing factors of water demand, the grey correlation method was used to analyze the relationship between elastic coefficient model variables. A natural logarithmic pretreatment method is proposed, and the forecast of domestic water demand in Zhengzhou City is taken as an example to compare and analyze the methods. The results show that the method is reasonable and effective. The application of grey correlation analysis is further enriched. The water demand prediction results are also in line with the actual situation, which can provide a reference basis for Zhengzhou water resources planning.
