Relationship between tourism number and air quality by carbon footprint measurement: a case study of Jiuzhaigou Scenic Area

Both the environmental and the ecological protection are key issues in the sustainable development of tourism. As a well-known world natural and cultural heritage, intensive study about the environment of Jiuzhaigou scenic spot has been launched since China's natural landscape protection. The field of low-carbon tourism is starting to be explored in China, and this article uses the life cycle assessment theory to evaluate the footprint of Jiuzhaigou. We find that the air quality is closely related to the number of tourists. Therefore, to maintain the environment of Jiuzhaigou, the number of tourists is proposed to restrict. The contribution of this paper is to provide pricing theory for attracting potential tourists and to give a theoretical basis for controlling the number of tourists in Jiuzhaigou Scenic Area.
