以宝鸡市为例,构建了灰色GM(1,N)自记忆城市生活需水预测模型,采用灰色斜率关联度筛选城市生活需水量的最主要影响因素,并考虑到建模中。实例结果表明,模型拟合和预测精度均较高,可为城市规划提供参考。 Taking Baoji City as an example, this paper constructs a prediction model of gray GM (1, N) self-remembering urban living water and selects the most influential factors of urban living water demand by gray slope correlation degree, and takes into account the modeling. The results show that the model fitting and prediction accuracy are high, which can provide reference for urban planning.
