Abstract: In view of the problem that the rationality of the evaluation index is not good and the reliability of the evaluation results is low, a comprehensive evaluation method of environmental pollution based on the improved principal component analysis is proposed. First collect air, water and soil pollution data of tourist attractions. Then, the original pollution data are cleaned, and the data clustering method is used to classify the pollution data. After that, the comprehensive evaluation index system of environmental pollution in tourist attractions is established. Finally, the entropy method is used to calculate the evaluation values of various indicators, and the comprehensive evaluation results of pollution in tourist attractions are obtained. The experimental results show that the correlation of the evaluation index is always controlled above 0.90, the convergence rate of the method is fast, the optimal solution can be approached within 150 iterations, and the application effect is good.

Keywords: tourist attractions; comprehensive evaluation of pollution; principal component analysis; weighted assignment; evaluation index; entropy method.
