【摘要】 为更好的探究聚类分析在地下水环境评价中的应用,结合重庆市藻渡水库工程,采用系统聚类法分析了水库枢纽和库区位置的地下水监测点与周围煤矿污染源之间的相互关系,运用灰色聚类法和改进的灰色聚类法对地下水监测点进行综合评价,并分析了两种方法的优缺点。最终将17个地下水监测点划分为未超标天然地下水和受煤矿开采污染的地下水两大类,分析了污染物来源并评价了污染程度,为藻渡水库工程的地下水污染防治提供了科学依据。更多还原

【Abstract】 To probe into the application of cluster analysis in groundwater environment assessment better,combining with the Zaodu reservoir project in the Chongqing Municipality,through hierarchical cluster method has analyzed relationship between groundwater monitoring points in reservoir hub and reservoir region,as well as peripheral coalmine pollution sources; through grey cluster method and improved grey cluster method carried out synthetic assessment for groundwater monitoring points and then analyzed advantages and disadvantages of the two methods. Finally,17 groundwater monitoring points have been classified into two categories: one is natural groundwater without overproof and another is polluted by coal mining. The paper also has analyzed pollutant sources and assessed pollution level,provided scientific basis for groundwater pollution control in Zaodu reservoir project.更多还原
