| 摘 要： | 采用BP神经网络建立了东北地区某水库水的浊度预测模型，同时针对该水库的地域特点，重点研究了冰封期对水源水水质预测的影响。结果表明，以浊度为预测对象，将水库的水质数据按照是否进入冰封期进行划分后建模，预测效果比划分之前有较明显的提高。

| Abstract: | Turbidity prediction model for the reservoir water in Northeast China with BP neural network was set up,at the same time the effect of ice-covered season on water quality prediction of water source was studied based on the characteristics of this area.The result showed that the efficiency of prediction was improved significantly after water quality data were divided according to ice-covered season and the establishment of the model. |

| Keywords: | BP neural network water quality prediction ice-covered season turbidity |
