| Abstract: | The shortcomings and the modeling conditions of BP networks were discussed, and the essential principles and modeling steps were thus put forward in this paper. As to water quality assessment, a new approach producing training set data, verification set data, testing set data and critical value set data randomly distributed between the critical values was established. The water quality assessment model was set up. |
