Through the analysis on applicability and characteristic of different prediction model of the trends method prediction of industrial water demand quota for ten thousand Yuan GDP,and based on the theory of combination forecast a combination optimal forecasting model of industrial water demand quota for ten thousand Yuan GDP was put forward ,using the MATLAB mathematical calculation software optimization algorithm was optimized and the problems in application of the trends method model were solved to some extent. The results show that the combination prediction model has higher precision and is more reliable than that of the single prediction model.
