基于生态足迹的理论模型,提出“旅游生态足迹指数”作为测量区域旅游可持续发展水平的重要指标。将该方法应用于广西沿海地区,计算2015年钦州、北海和防城港三市的旅游生态足迹、当地居民生态足迹、区域总体生态承载力、生态盈余/赤字,以及旅游生态足迹指数。结果表明:北海市生态赤字为296 173.14 hm~2,旅游生态足迹指数为-40.9%,区域旅游发展处于不可持续的状态;钦州市生态足迹盈余为338 338.57 hm~2,旅游生态足迹指数为20.2%;防城港市旅游生态足迹盈余为183 534.04 hm~2,旅游生态足迹指数为24.3%,区域旅游发展处于弱可持续状态。 Based on the theoretical model of ecological footprint, “Tourism Ecological Footprint Index” is proposed as an important index to measure the sustainable development of tourism in the region. The method is applied to the coastal areas in Guangxi. The tourism ecological footprint, the ecological footprint of the local residents, the overall ecological carrying capacity, the ecological surplus / deficit, and the tourism ecological footprint index of the three cities of Qinzhou, Beihai and Fangchenggang in 2015 are calculated. The results showed that the ecological deficit in Beihai was 296 173.14 hm ~ 2, the index of tourism ecological footprint was -40.9%, and the development of regional tourism was unsustainable. The ecological footprint of Qinzhou was 338 338.57 hm ~ 2 and the index of tourism ecological footprint was 20.2 %. The surplus of tourism ecological footprint in Fangchenggang City was 183 534.04 hm ~ 2, and the tourism ecological footprint index was 24.3%. Regional tourism development was in a weak and sustainable state.
