摘　　要：旅游目的地系统碳源、碳汇的计算与分析,不仅是旅游业节能减排政策制定的重要依据,也是旅游与环境相互关系研究的一个新的科学命题。以庐山风景区为例,计算并分析了2010年的碳源及碳汇。结果表明:(1)2010年庐山风景区包括本地居民和旅游者的总碳排放为108 697 t。其中,本地居民占碳排放总量的19.52%,旅游者占碳排放总量的80.48%。在旅游者碳排放中,旅游交通碳排放占50.24%,旅游住宿碳排放占38.04%,旅游食物消费碳排放占10.65%,旅游活动碳排放仅占1.07%;(2)2010年庐山风景区内陆地生态系统碳吸收为9 447 t;(3)从碳源、碳汇均衡角度看,庐山陆地生态系统的固碳量吸收了区内碳排放的23.47%。但由于旅游者的区际流动和旅游业的产业关联性强,陆地生态系统的碳吸收仅占区内和区外碳排放总量的8.69%,旅游业使庐山成为一个显著的碳源。Climate change is the single most important global environmental issue facing the world today.The tourism industry plays a role in the global anthropogenic impact of carbon dioxide（CO2） emissions.Climate change and its associated implications are beginning to emerge as a major topic of discussion and research within tourism studies.The tourism sector uses an extensive range of transport energy.This includes moving visitors to,from and within tourist destinations,along with travel to accommodation facilities and tourism activities.Tourist destinations cover land areas that include forests,lakes and farms.These features can absorb carbon dioxide through photosynthesis and sediment accumulation.The calculation and analysis of carbon sources and storage sinks,within tourist destinations,is important for emission reduction policy and to encourage the tourism sector to save energy.Further,it is also the basis of a new research field examining the relationship between tourism and the environment.Using the Lushan Scenic Area in Jiangxi province,China,as a case study,we calculate and analyze the carbon emissions and associated absorption in this region in 2010. The results show total carbon emissions in the Lushan Scenic Area were 108,697t in 2010.Local residents contributed to 19.52% of emissions while tourists accounted for 80.48%.Of the total carbon discharged by locals,food consumption accounted for 82.89%,energy use 11.79%,and traffic emissions 5.31%.Of the total carbon discharged by tourists,traffic emissions accounted for 50.24%,lodging 38.04%,food consumption 10.65%,and tourist activities 1.07%.Mitigation of carbon emissions can be achieved using the principles of elimination,reduction,substitution and offsetting.Practical measures employing these principles include reducing energy use,becoming more energy efficient,using sustainable energy sources and the compensation of unavoidable emissions through offsetting schemes.The control of transport induced carbon emissions is crucial,particularly in the tourism se
