Abstract:

Ecotourism is a new-style tour which has been developed with the adaptation to people’s desire for returning to the nature and protecting environment during the 20th century. As a green tour, ecotourism has drawn world’s attention since its beginning. Currently it is becoming one of the main trends in tourism development in the 21st century. In this thesis, the ecological impacts of ecotourism on environments were studied in both theory and practice. The author tried to put forward the China-special ecotourism, and then study its ecological impacts through quantitative ecological methods. At last, several suitable suggestions for tour developers and managers were raised. Vegetation landscapes were not only important scenic resources, but also levers of harmonizing their ecological balance. So it was important to study the relationship between tourism and vegetation environment in the nature reserve. The relationship between landscape characteristics of tourist vegetation and geographical factors was analyzed in this paper. By this study, we can compare the impact of physical geographical factors with that of human geographical factors on vegetation landscape characteristics, and realized the rule of tourism on vegetation landscape. The result showed that elevation was only correlated evidently to landscape characteristics. The width of tourist road was correlated evidently to landscape important value, tourism influencing index, vegetation layer cover. Physical environment had little effect on tourist vegetation landscape compared to human geographical factor. In addition, the correlation between proportions in community structure, proportion of species companying with human being and geographical factor showed that it can not reflect ecological environment as a good evaluation standard.
