Research on Island Tourism Ecological Security Evaluation Model Based on the Ecological Footprints

Based on the analysis of the domestic and foreign researches, the paper puts forward three key elements to evaluate the island tourism ecological security by the method of ecological footprint, which are the rigid background ecological footprint of the tourist destination islands, the rigid tourism ecological footprint and the ecosystem carrying capacity, and based on the island characteristics, a mathematical model involving the three key elements is established, on the foundation of which a two ecological security indices——ecological security index and ecological efficiency index——is designed to evaluate island tourism ecological security, and the critical value of the two indices under different conditions is also worked out. Thereby, accurate measurement of the island’s tourism ecological security and the sustainable development degree is made possible from the two dimensions.
