Abstract
Studying eco-sustainability of tourism areas is part of sustainable development research. In tourism areas, the ecosystem comprises both the environment and the human system. The environmental system is basically physical, whereas the human system, consisting of both tourists and residents, is the dominant factor driving ecosystem change. If the combined influence of tourists and residents exceeds the carrying capacity of the environment, which is the ecological threshold of eco-sustainability in the tourism area, then the structure, function and stability of the environment will degenerate. Hence, eco-sustainability assessment of tourism areas should be based on analyses of the relationship between the influence of tourists and residents on the environment and the environmental carrying capacity. Using ecological footprint and tourism ecological footprint models, we developed and applied a synthetic assessment index system for eco-sustainability of tourism areas in Lijiang County, Yunnan Province, China, to conduct a quantitative spatial assessment for 2001. The eco-sustainability of Lijiang was high, with a harmonious relationship between regional socioeconomic development and the ecological environment. There were significant spatial differences in eco-sustainability among 24 towns in the region because of spatial heterogeneity in socioeconomic status, tourism development and environmental elements.
