| 摘 要： | 通过分析影响下辽河平原地区地下水特殊脆弱性的因子，建立基于GIS平台的预测因子图层数据库，利用Arc-Wofe系统进行证据权重法模拟预测，对下辽河平原区地下水硝酸盐氮特殊脆弱性进行研究，得到硝酸盐氮浓度后验概率分布图。从预测结果看，后验概率高或较高的地区正是硝酸盐氮浓度已经比较高的地区或预测的硝酸盐氮浓度高值区；并通过多种途径检验了研究结果的客观合理性。

| Abstract: | The prediction factor database was constructed by GIS flat according to the analysis of factors which influence the groundwater intrinsic vulnerability in the lower reach of Liaohe River, and then the weight of evidence method was applied to simulate the groundwater intrinsic vulnerability on the Arc-Wofe system, the posteriori probability distribution map of nitrate concentration was obtained. The prediction result showed that the region with high posteriori probability usually was corresponding to a high nitrate concentation, and several methods were applied to testify the rationality of result. |
