兰州市2004年旅游生态足迹计算及其对生态影响的分析

The Calculation and Analysis of Tourism Ecological Footprint of Lanzhou City in 2004

基于生态足迹模型,结合旅游者的生态消费及结构特征,将旅游生态足迹引入区域旅游生态影响评估,以兰州市为研究对象,计算分析了2004年兰州市旅游生态足迹。结果表明,2004年兰州市的人均本底生态足迹为1.97965hm2,生态承载力为0.28677hm2,人均本底生态赤字为1.69288hm2,叠加旅游生态足迹0.1062189hm2,生态赤字达1.7991hm2,其中旅游生态足迹的生态赤字"贡献"为5.904%,对兰州市生态赤字的"贡献"不大。但是,旅游者的跨区域流动引起旅游生态足迹的区际转移与交换,使兰州市游客的旅游生态足迹中有一部分转移至区外。

Taking Lanzhou city for example,it calculated and analyzed the tourism ecological footprint in 2004 based on the ecological footprint model.The results showed that the per capita of the background ecological footprint was 1.97965hm2,the ecological deficit per capita was 1.69288 hm2,the superposition tourism ecological footprint was 0.1062189 hm2 and the ecological deficit was 1.7991 hm2,about the 5.904% of it that comes from tourism ecological deficit and there is a little contribution to Lanzhou ecological deficit.However,the shift of TEF among regions resulted in transfer and exchange ecological footprint among regions,a part of the ecological footprint of Lanzhou city was transferred to other regions.
