| Abstract: | This article logarithmically transforms the original data serial to slow down changes in trend. In this article the model is carried out by Matlab in order to simplify the calculating. We apply the improved modle to the water quality forecasting of Qian Wan sea area of Jiao Zhou Bay. The results indicate that the forecasting precision of the improved model is better for monotonically increasing data serial, and the forecasting results fit well with measured values. |
