Abstract: Issues persist in the evaluation of environmental pollution at tourist sites, characterised by inadequate indicator grading and membership degrees, along with significant average absolute error values in evaluations. Consequently, this paper introduces a classification evaluation approach for environmental pollution at tourist sites, utilising a fuzzy hierarchical evaluation technique. Initially, the analytic hierarchy process (AHP) is employed to develop a hierarchical structure model and establish an evaluation index system. Subsequently, indicator data is standardised, and the relationship between indicator levels is determined based on the average random consistency ratio. Ultimately, fuzzy and weight judgement matrices are constructed for both single-level and multi-level fuzzy evaluation. Experimental outcomes indicate that this methodology significantly enhances the precision of evaluation and the appropriateness of indicator grading.

Keywords: fuzzy analytic hierarchy process; tourist attractions; ecological environment; pollution classification; standardisation; evaluation criteria.
