 Evaluation method of ecological vulnerability of scenic spots based on entropy weight TOPSIS modelJiong Li International Journal of Environmental Technology and Management, 2023, vol. 26, issue 1/2, 14-26 Abstract: In order to solve the problem of poor accuracy of traditional ecological vulnerability assessment methods, an ecological vulnerability assessment method of scenic spots based on entropy weight TOPSIS model is proposed. Firstly, it analyses the natural environment and conditions of the scenic spot, determines the ecological vulnerability evaluation index of the scenic spot, and constructs the evaluation index system through spatial principal component analysis. Then, the evaluation indexes are standardised and graded according to the ecological vulnerability index of scenic spots. Finally, the weight of ecological vulnerability index is calculated by using entropy weight TOPSIS model, and the ecological vulnerability index is determined. After building the ecological vulnerability assessment model of scenic spots, input the ecological vulnerability indicators into the model and output the assessment results. The results show that the accuracy of this method is as high as 0.98. Keywords: evaluation factor; entropy weight TOPSIS model; ecological vulnerability; evaluation method.
