摘　　要：本论文以西南岩溶山区某石化类场地为例,以污染场地风险评价导则作为指导,结合国内外地下水污染风险评价方法,在完成场地地下水污染风险识别以及源项分析的基础上,建立了符合场区实际水文地质条件的地下水水流及溶质运移数值模型,对不同情形下污染物泄露对场区浅层孔隙-溶蚀裂隙地下水的影响进行预测,结合预测结果建立了场区地下水污染风险的综合评价体系,运用该体系确定了场区建设对周边地下水造成的污染风险等级,并对场区地下水污染的风险管理提出了科学合理的建议,对于最大限度地降低场区地下水污染风险、地下水环境的保护具有指导性的实际意义。This paper takes a petrochemical site as an example in in Southwest karst-mountains, and take the risk evaluation guideline of contaminated sites as a guide, on the basis of risk identification and sources analysis, established the numerical model of groundwater flow and solute transport, which is accord with the actual hydrogeological condition of the area, make predictions for the influence of leaks in the shallow pore-karst fissure groundwater, established the comprehensive evaluation system of groundwater pollution risk combined with the predicted results, using the system to determine the pollution risk level of the surrounding groundwater caused by field construction, put forward scientific and reasonable suggestions for the risk management of groundwater pollution, and have guiding significance for the reduction of groundwater pollution risk and the protection of field groundwater environment.
