| Abstract: | The time series of the ice-conditions information in Inner Mongolia Reach of the Yellow River were analyzed by the cross-correlation method in mathematical statistics,so the predicted factors were shifted out to build the adaptive neural network predicting model.The results show that the predicted effects of flowing-ice date,frozen date and breakup date are better,best and qualified. |
| Keywords: | adaptive neural network ice-conditions prediction Inner Mongolia Reach Yellow River |
