北京市旅游餐饮生态足迹实证分析

研究北京旅游生态环境保护和建设的有效途径对北京的旅游业可持续发展及整个北京生态环境的治理与管理具有重要意义。基于旅游生态足迹模型和来京旅游者的生物、能源消费及结构特征，文章通过计算分析2004-2006年北京市外来旅游者旅游餐饮生态足迹认为：北京市外来旅游者人均餐饮生态足迹特别是对能源的需求呈增加趋势，平均增长率为4.41%；北京的生物资源及能源供给大部分来自外部，生态负担转嫁范围大，旅游生态环境处在不可持续状态。建议北京市提高能源利用率，高效利用现有旅游设施，大力发展生态旅游等旅游模式，减少旅游带来的环境冲击，促进旅游业可持续发展。

CASE STUDY ON ECOLOGICAL FOOTPRINT IN BEIJING'S TOURISM FOOD INDUSTRY

Approaches to environmental protection and construction are important for the sustainable development of tourism industry in Beijing, and as well as the ecological environment maintenance and management. This paper, based on tourism ecological footprint models and tourist's biological and energy consumption and its structure, analyzes the ecological footprint in Beijing's tourism food industry from external tourists during 2004 to 2006, indicates a rising energy demand in per capital food ecological footprint, up by 4.41% on average. The biological resources and energy are most supplied from out of Beijing, which is difficult in transferring the biological burden, implying a non-sustainable development of tourism ecological environment. This paper suggests increasing energy utilization efficiency, making a full use of existing tourism facilitates, developing ecological tourism, decreasing the impact of tourism on environment and promoting the sustainable development of tourism industry.
