Correlation Model-Based Principal Component Analysis on the Application on Water Body Eutrophication Evaluation
In this paper, based on the correlation analysis and by combining the principal component analysis, a correlation evaluation model-based principal component analysis is established. In the process of the water body evaluation eutrophication, a correlation analysis is conducted between the sample matrix and the standard matrix of the water body eutrophication evaluation. The sequence which has the closest relationship is the grade for evaluation. The example has shown that the correlation evaluation model based on the principal component analysis avoids the subjective factor of the weight, and the calculation is simple and clear. This method provides a new approach to evaluate the water body eutrophication.
