摘要
以兰州市为例,通过一系列的实证资料,运用主成分分析法,建立城市化与城市居民用水的数学模型,对两者的相互关系进行了研究,发现兰州市城市化水平与城市居民用水之间有线性相关关系,线性回归模型为Y=229.659+1.093X。城市化水平越高,城市居民用水量越多,供水条件要求越高;反之,城市居民用水量越少,供水条件要求越低。
Taking Lanzhou city as an example, through a series of real example materials, using principal component analysis, mathematics model is set up to carry on research to the inter reaction between urbanization process and the water consumption. It is found the urbanization level and urbanite water in Lanzhou have linear relation, the linear regression model is Y = 229. 659 + 1. 093X:the higher the urbanization level is the higher the urbanite water is consumpted and the supply water condition is required. On the contrary, the lower the urbanization level is the lower the urbanite water consumoted and the supply water is reauires.
