Study on Tourism Ecological Security Evaluation and Optimization of Coastal Cities in Beibu Gulf
Based on the DPSIR model,a tourism ecological security evaluation index system for coastal cities in the Beibu Gulf was constructed,consisting of 5-criteria layer indicators and 22 basic indicators.The Analytic Hi-erarchy Process and Fuzzy Comprehensive Evaluation Model were comprehensively used to quantitatively evalu-ate the tourism ecological security of coastal cities in the Beibu Gulf in 2019.The research results show that the tourism ecological security index of the seven coastal cities in the Beibu Gulf is between 0.6 and 0.8,belonging to the"relatively safe"level.Among them,Yangjiang and Qinzhou have relatively high levels of tourism ecological security,followed closely by Haikou,Maoming,and Beihai,while Fangchenggang and Zhanjiang have relatively low levels;The five subsystems of tourism ecological security all belong to the level of"safety"or above,with relatively better performance in the impact and pressure subsystems,moderate performance in the driving force and state subsystems,and relatively poor performance in the response subsystems.There are significant scores a-mong the five subsystems of each city.Finally,based on the evaluation results,optimization strategies for tourism ecological securityare proposed for seven coastal tourism cities in the Beibu Gulf region.
