Quantitative Evaluation of the Impact of Sustainable Eco-Tourism Policy on Tourism Environmental Capacity in Dali City

The sustainable eco-tourism policies of Dali City represent a pivotal foundation for fostering the harmonious integration of local ecology and tourism. To appraise the effectiveness of these policies, this study formulates an evaluation framework utilizing the PMC index model. The analysis encompasses 16 sustainable ecotourism policies and their associated environmental indicators in Dali City, subsequently constructing an evaluation system that integrates the PMC index with tourism environmental capacity. Evaluation proceeds via the PMC index and its surface map representation. The results reveal a commendable average PMC index of 6.176 for the 16 policies, indicating a generally high level of performance. This underscores Dali City's substantial commitment to the conjoined development of ecology and tourism, as evidenced by the preliminary establishment of a comprehensive policy system and operational network spanning the entire city. Incorporating the tourism environmental capacity model, the policies pertaining to facilities and ecological environment indicators score 5.440 and 5.638 respectively, falling below the average benchmark for similar-level assessments. These findings suggest that while the overarching design of Dali City's sustainable ecotourism policies is sound, there is scope for enhancement in focusing policy efforts on ecological and facility environment capacity. Future policy formulations should prioritize advancements in policy timeliness, scope, incentives, and constraints, fostering interdepartmental collaboration for coordinated governance. Furthermore, enhancing the comprehensiveness and efficacy of policies will contribute to fostering eco-tourism in Dali City and fostering a mutually beneficial relationship between ecological preservation and economic prosperity.
