title: [Uncertainty analysis of groundwater protection and control zoning in Beijing plain].
abstract: Groundwater pollution prevention mapping has important meaning to groundwater protection, pollution prevention and effective management. A mapping method was built through combining groundwater pollution risk assessment, groundwater value and wellhead protection area zoning. To make the method more accurate, two series of uncertainty analysis were performed and discussed. One was performed by changing the weights of the toxicity, mobility and degradation of pollutants, and the other was by changing the weights of groundwater pollution risk, groundwater value and wellhead protection area zoning. The results showed that the weights of groundwater pollution risk, groundwater value and wellhead protection area zoning were more sensitive than the weights of toxicity, mobility and degradation of pollutants.
