中文摘要：

利用生态足迹的理论与方法，基于GIS技术，在实地问卷调查的基础上，结合入境游客行为，完善了旅游生态足迹的概念。分析了旅游生态足迹的基本构成，提出了旅游生态足迹计量模型。以西安市2002年入境游客为例。对入境游客的旅游生态足迹作了初步探讨。结果表明，西安市入境游客人均生态足迹为0．01569hm^2，约占该市现有城镇居民年人均生态足迹的1．17％。可以看出，在旅游热点城市旅游生态足迹对区域生态足迹有着不可忽视的影响，是区域生态赤字扩大的因素之一。进一步分析表明，旅游生态足迹结构组成中，餐饮的旅游生态足迹居绝对主导地位。约占54．09％。西安市旅游生态足迹效率很高，该市应大力发展入境旅游以提高旅游收入。最后指出了旅游生态足迹计算中存在的问题以及其在旅游可持续发展研究中的应用前景。

英文摘要：

Based on GIS and investigation on the spot and combining the research on the inbound tourist＇s behavior and the theory and method of the ecological footprint, the article perfects the concept of the ecological footprint of travel and analyses the basic composition and proposes measure-model of it. Take inbound tourist in 2002 in Xi＇an as an example, the article studies the ecological footprint of travel of inbound tourists. The result indicates that every person＇ s per capita ecological footprint of inbound tourist in Xi＇an is 0. 015 69 hm^2, which accounts for 1.17% of the annual per capita ecological footprint of existing urban residents in Xi＇an. So, the conclusion is that the ecological footprint of travel has a noticeable influence to the ecological footprint in tourist hot spot, at the same time it is one of important attributes that the ecological deficit of area expands. To analyse further, ecological footprint of food and beverage occupies absolutely dominant position and accounts for 54.09 %. But, the ecological footprint of doing shopping is most effective in touristic ecological footprint structure. The touristic ecological footprint in Xi＇an is very efficient, we should develop inbound tour and enhance the traveling income. Finally, the article points out some problems existed in calculation of touristic ecological footprint as well as the prospects in travel sustainable development.
