| 摘 要： | 采用主成分分析法对咸阳市11年地下水动态观测资料进行分析,得到咸阳市地下水位动态变化规律。结果表明：地下水位动态变化的主要影响因子是地下水开采量和降水补给量,并采用灰色关联度分析方法（PCA）对咸阳市地下水影响因素的敏感性进行分析,其分析结果同主成分分析结果基本吻合。

| Abstract: | In order to determine the dynamic change regulation and main dynamic driving factors of underground water level in Xianyang City,the principal component analysis(PCA) method is used here for analysis.The conclusion is obtained that the main factors influencing the dynamic change of underground water level are the groundwater exploitation and precipitation recharge.At the same time,the grey relational analysis method is used to analyze the sensitivity of groundwater influencing factors in Xianyang City,the result from which is same as that from PCA method. |
