- 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.
