| Abstract: | The appraisal and forecast problem of water quality of Yangtze River are discussed. The main statistical data of the past decade was analyzed. The exponential method, optimal model, two order linear difference equation model were utilized, and the appraisal and forecast to the water quality of Yangtze River were carried out. Some feasible proposal and opinions about the water pollution problem Yangtze River were put forward. Finally the error analysis of the forecast results , some appraisals and promotion of the model were carried on. |
