%X Forecasting and evaluation water quality is a complicated problem due to its nonlinearity and uncertainty. Least square support vector machine(LSSVM) has been successfully employed to solve regression and time series problem. This paper proposed a novel IGALSSVM model.The model based on a new genetic algorithm, intelligent genetic algorithm to optimize the parameters of LSSVM. In addition, applied the model to classify and forecast water quality of Changjiang River. Experimental results show that IGALSSVM model performs better than neural networks ,implying that IGALSSVM is very practical.
