Evaluation of Ecological Vulnerability in a Tourist Attraction

Eco-environment provides the material basis for people to survive and develop. The eco-environment in a tourist destination determines the developing prospect of its economy and society. Based on identified influencing factors and evaluation index selection principle of ecological vulnerability in a tourist attraction, the paper established a corresponding evaluation index system. In combination with years of related environmental monitoring data, an analytic hierarchy model was used to compute weight coefficients of all evaluation indices. The ecological vulnerability in a tourist attraction was accordingly divided into four levels: I low vulnerability, II intermediate vulnerability, III high vulnerability, and IV ultrahigh vulnerability. They were graded, with local data records of previous year as the reference. Then, membership function was employed to establish a fuzzy comprehensive evaluation matrix, on whose basis an evaluation model for ecological vulnerability in a tourist attraction was built up as well. Finally, the paper undertook simulation calculation on relevant data in Weifang city, Shandong province, and the simulation result is congruent with local situations. The scientific, professional and rational method proposed in the paper provides theoretical basis for evaluation of ecological vulnerability in a tourist attraction.
