Evaluation method of environmental carrying capacity of tourist attraction to be developed based on marginal utility analysis

In order to achieve a reliable analysis of environmental carrying capacity, the paper proposes an evaluation method of environmental carrying capacity of tourist attraction to be developed based on marginal utility analysis. Firstly, establish an evaluation index system for environmental carrying capacity and use the Simpson distribution function to calculate the importance of the evaluation indicators. Then, Cobb-Douglas marginal production function model is used to simulate the utilisation and consumption process of tourist attraction to be developed. Finally, based on the demand and supply of the scenic area environment, the entropy method is used to calculate the environmental carrying capacity evaluation coefficient. Experiment shows that the recognition accuracy of the method for indicator weights remains above 94.0%, and the fit between the evaluation results and the actual results is between 92.43%-95.48%, indicating that the evaluation results of this method are more effective.
