Abstract

In this paper, Correlation analysis is used to analyze Fractal dimension to valuation of eutrophication. The results are showed that correlation dimension of five index with the corresponding index are the same direction. In the fact, correlation dimension of four indexes with the corresponding index are the same direction and correlation dimension of one index with the corresponding index is the different direction. The diversification of the different direction will cause an adverse change in the evaluation results and is the opposite of the same direction. So we provide a method for pre-processing of data that is normalization method and conducted a correlation analysis and verification of accuracy. The results are showed that correlation dimension of five indexes with the corresponding index are the same direction, and that the correlation between correlation dimension and the corresponding index is very high, and that the accuracy of evaluation results is very high.
