| Abstract |
A scientific evaluation indicator system is critical for assessing and predicting urban environmental vulnerability. This study establishes an indicator system of urban environmental vulnerability based on ecological sensitivity, resilience, and pressure and proposes a comprehensive screening method using the coefficient of variation and anti-image correlation matrix to improve the evaluation result of urban environmental vulnerability. The indi-cator screening method improves the reliability of the evaluation results. The proposed method is compared with Pearson correlation analysis to demonstrate the advantages of our method for calculating the information interpretation intensity and the cumulative contribution rate. The calculated results are compared with the threshold values to verify the suitability of the constructed index system. The results show that the information interpretation intensity of the selected indicators system is 1.061, and the cumulative information contribution rate is 89.78%. The selected indicators system accurately reflects urban environmental vulnerability. |
