摘要
选取中国北方某一典型岩溶潜水水源地为例,利用DRWM模型和DRWMLPE模型分别对其地下水本质脆弱性和地下水污染风险进行了评价.评价结果表明,研究区内地下水异常现象的发生与地下水本质脆弱性没有明显的相关性,而与地下水污染风险性具有较好的相关性,进而阐明了地下水本质脆弱性、污染负荷与污染风险之间的复杂关系.单参数敏感性分析结果验证了DRWMLPE评价模型的合理性并获知包气带介质是水源地地下水污染风险评价中最敏感的因素.DRWMLPE评价模型可推广到其他岩溶地下水污染风险评价,为地下水资源的可持续合理开发利用提供科学依据.
Typical karst-phreatic water source in northern China was taken as an example, to assess intrinsic vulnerability of groundwater and risk assessment of groundwater pollution each based on the DRWM and DRWMLPE models respectively. It was found that groundwater anomalies were related to risk of groundwater pollution rather than intrinsic vulnerability of groundwater, illustrating a complicated relationship among intrinsic vulnerability of groundwater, sources of pollution and risk of groundwater pollution. Unsaturated zone media was found to be the most sensitive factor in risk assessment of groundwater pollution by using single-parameter sensitivity method, validating rationality of DRWMLPE model. The DRWMLPE model could be widely used in other karst-phreatic through improvements, providing scientific evidences for sustainable utilization of groundwater resources.
