| 摘 要： | 运用逐步线性回归的理论方法，分析研究区的地下水水质指标间的相关性，研究区属砷元素富集地区，对研究区建立砷含量与其他指标之间的线性回归模型，确定砷含量与HPO4-2、Fe、I-，Br-的含量相关性较显著。此模型可以用于研究区的地下水环境的规划、评价、研究工作中。

| Abstract: | The paper tries to analyze the relationship between groundwater quality indexes in the studied area with Step- wise Linear Regression theory. As the studied area is with high level of arsenic, the paper builds a LRM （ Linear Regression Model） on the basis of the relationship between arsenic and other quality indexes. The model shows that content of arsenic has close relationship with the content of HPO4 -2, Fe, I- and Br-. The model can be applied to groundwater environment plan- ning, assessment and research. |
