工业园区作为重要的地下水污染源，以园区为研究对象开展地下水污染风险评价对推进地下水污染防治工作具有重要意义，以四川省西南某工业园区为例，采用迭置指数法对园区地下水污染风险进行评价，并利用地下水硝酸盐浓度与地下水污染风险等级之间的Spearman等级相关系数，对评价结果进行验证。研究结果表明:研究区地下水污染风险整体较低，大部分区域为中、低风险区，高风险区域占比3。24％，在研究区中部、北部零星分布。Spearman等级相关系数p=0。81，相关性显著，表明迭置指数法可应用于工业园区地下水污染评价之中。研究结果为降低工业园区地下水污染风险和园区地下水污染防治工作提供了科学依据。
Application of Overlayand Index Method for Assessment of Groundwater Contamination Risk in Industrial Park
An industrial park is a key groundwater pollution source.Therefore,it is of great significance to carry out groundwater pollution risk assessment on an industrial park to promote the prevention and control of groundwater pollution.This paper took an industrial park in southwest Sichuan province as an example,assessed itsgroundwater contamination risk by the overlay and index method,and verified the assessment results by using the Spearman's coefficient between the nitrate concentration in the groundwater and the groundwater contamination risk.The assessed results indicated:the studied industrial park as a whole was at low risk of groundwater contamination;most areas were at low and medium risk;and the high-risk area accounted for 3.24％,scattered in the central and northern part.The Spearman's coefficient is p=0.81,indicating the correlation was significant,therefore,the overlay and index method is suitable to assess the groundwater contamination risk of industrial park.The research results provide a scientific basis for reducing the risk of groundwater pollution in industrial parks and the prevention and control of groundwater pollution in industrial parks.
