Abstract: The relationship between vegetation and tourism industry in the Tianlong Mountains was analyzed in this paper. Five standards─sensitive level, community landscape importance value, information index of species diversity, tourist impact index and proportion of plants accompanied with mankind was used. The results show that sensitive level has inverse relation to landscape importance value and information index; tourist impact index is positively related to the rate of plants accompanied with mankind. These facts indicate the regularity of tourist has an impact on vegetation objectively. It is practical to use these above methods to appraise tourist impacts on vegetation.
