Abstract: With the development of the tourism and the improvement of common people's consumption level, the catering industry has become one of important industrial categories in tourist city. The quantitative analysis of catering food consumption and its resources and environmental cost will be helpful to the optimization of food supply model and the sustainable development of catering industry in tourist cities. Based on the field survey data, this paper calculated the total amount of catering food consumption in Lhasa City, a typical highland tourist city. Further, from the perspective of life cycle, the resources and environment cost of catering food consumption in Lhasa was calculated through constructing ecological footprint model. The main conclusions were as follows: 1) In 2011 and 2012, the food consumption per capita was 923.7 g in Lhasa, and the food eaten by people was 780.3 g per capita. There was significant difference between the food consumptions of tourists and local residents. 2) The total amount of catering food consumption in Lhasa increased from 19 498 t in 2006 to 41 506 t in 2013, with 112.9% of increment. Among the total amount of catering food consumption in 2013, local consumers consumed 27 983 t, and tourists consumed 13 523 t. By categories, the food consumption included 9 712 t of meat, 2 843 t of aquatic, 15 696 t of vegetables, 6 034 t of staple food, 4 885 t of fruits and 1 931 t of drinks and wine. 3) In 2013, biological and ecological footprint of catering food consumption in Lhasa was 226 681 hm2, equivalent to 6.3 times of the total cultivated land area of the entire Lhasa. The ecological footprint of catering food waste was 653 hm2 in 2013. Most of the ecological footprint catering food consumption consumed in Lhasa came from outside of the Tibet Autonomous Region, while internal supply of ecological footprint accounted for only 15% of the total ecological footprint. External provinces with a larger share of the supply included neighboring provinces such as Gansu, Ningxia, Qinghai, and some eastern provinces.
