| Abstract: | The basic theory and calculating process of BP neural network is introduced in the paper. Then, BP neural network model is applied to the groundwater quality evaluation for the downstream of Yitong River with 6-11-5 three-layer network structure. The comparison of the evaluated result with Nemero Index, Fuzzy comprehensive method and Matter-element Analysis shows that BP neural network is simple in calculation, objective and exact in evaluation results and also well reflects the whole condition of groundwater quality. |
