Abstract: Global-climate-change problem poses new demands for tourism. Estimating carbon emissions from tourism is the basis for further research on low-carbon tourism, which is of great significance to the development of low-carbon tourism.Based on input-output method, this paper estimates the direct carbon emissions of tourism in Hunan province from 2008 to 2014, analyzes the evolution trend of carbon intensity and per-person carbon emission in tourism industry of Hunan Province, and uses GRA method to analyze the correlation of each tourism sectors impact of the total tourism carbon emission. The research shows: (1) The direct carbon emissions of Hunan tourism from 2008 to 2014 grew rapidly, from 2.9525 million tons to 7.8314 million tons; (2)Transport, catering, shopping and accommodation sector accounted for more than 90% of total tourism emissions from 2008 to 2014, those are main directions of carbon reduction. (3)The tourism carbon intensity and per-person carbon emission of Hunan Province show a downward evolution trend. (4)The correlation between sectors carbon emissions and total carbon emissions of Hunan tourism involves food, housing, transportation, sightseeing, shopping and entertainment is ranked as follows: Sightseeing(0.9296)>Tourism Catering(0.8456)>Tourism Transportation(0.8254)>Tourist Accommodation (0.8092)>Travel Shopping (0.7109)>Others (0.5732). (5)Changing traditional way of sightseeing is the breakthrough point for Energy conservation of tourism. Also, promoting low-carbon transportation concept and low-carbon transportation mode are Equally important.

摘要： 全球气候变化问题对旅游业提出了新的要求。测算旅游业碳排放是深入研究低碳旅游的基础，对低碳旅游发展具有重要意义。基于投入产出法较为准确的估算了2008—2014年湖南省旅游业的直接碳排放，分析了湖南省旅游业的碳强度与人均碳排放的演变趋势，运用GRA关联法分析了湖南省旅游业各部门对碳排放影响的关联度。研究表明：（1）2008—2014年，湖南省旅游业直接碳排放增长较快，从295.25万吨增长到783.14万吨；（2）湖南省交通、餐饮、购物和住宿部门的碳排放占到了旅游业总排放的90%以上，是旅游业减碳化的主攻方向；（3）湖南省旅游业碳强度与人均碳排放呈现波动下降的趋势；（4）湖南省旅游业吃、住、行、游、购、娱六部门的碳排放与总排放的关联度排序为：旅游游览（0.9296）＞旅游餐饮（0.8456）＞旅游交通（0.8254）＞旅游住宿（0.8092）＞旅游购物（0.7109）＞其他（0.5732）；（5）旅游业节能减排的突破点在于改变传统游览方式，重点在于促进交通理念和交通模式低碳化。
