| 摘 要： | 以兰州市为例，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2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具有显著线性相关关系，线性回归模型为K2=-0.408＋0.917K1．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．

| Abstract: | Take Lanzhou City as an example,using principal component analysis,a mathematical model is set up to research the interrelation between urbanization process and the water for living.It is found the urbanization level and urbanite water in Lanzhou City have linear reaction,the linear regression model is K2=-0.408 0.917K1.The higher of the urbanization level makes the more urbanite water consumption and requires the higher supply water condition.On the contrary,the lower of the urbanization level makes the less urbanite water consumption and requires the lower supply water. |

| Keywords: | urbanite water consumption urbanization principal component analysis Lanzhou City |
