目的地旅游道路间接能耗与碳排放分析

Analysis of Indirect Energy Consumption and Carbon Emission of Travel Roads in Heritage Site

旅游道路是影响旅游目的地节能减排与可持续发展的关键因素之一。选择武陵源风景名胜区作为案例区,运用生命周期理论与物质流理论,构建旅游道路间接能耗与碳排放测度模型,运用自下而上法测度与分析1979~2010年武陵源风景名胜区的旅游道路间接能耗与碳排放。结果表明：（1）我国不同等级公路的每功能单位年均间接能耗与碳排放量呈现明显等级差异,高速公路八车道最高（5751.04 GJ与693 t）,五级公路最低（38.34 GJ与4.62 t）。（2）武陵源旅游道路在1979~1989年间旅游道路间接消耗各类能源与排放的二氧化碳的年均增长率最高,分别均高于18.5%与18.63%,此后逐年下降,2005~2010年间呈现负增长率。（3）1979年武陵源风景名胜区旅游道路的年均间接能耗与年均间接碳排放分别为5827.70 GJ与702.24 t,2010年分别为68 414.46 GJ与8243.90 t。

Travel road is one of the key factors influencing the energy-saving and emission-reduction and sustainable development for tourism in destination.Wulingyuan Scenic Spot was chosen as the case research area and by applying lifecycle theory and substance circulation theory,model was constructed to measure indirect energy consumption of travel roads and carbon emission of the area from 1979 to 2010 by adopting bottom-up approach.The result shows that：（1） there are significant rank difference between Chinese roads of different grades concerning annual average indirect energy consumption and carbon emission per functional unit.Eight-lane expressway（5751.04 GJ and 693 t） ranks first while fivelane expressway（38.34 GJ and 4.62 t） ranks last.（2） The annual average growth rate of indirect energy consumption and carbon emission of Wulingyuan travel roads was highest during 1979-1989,above 18.5% and 18.63% respectively.Since 1989,it has decreased year by year and there was negative growth rate during 2005-2010.（3） The annual average indirect energy consumption of Wulingyuan travel roads and carbon emission was 5827.70 GJ and 702.24 t in 1979,68 414.46 GJ and 8243.90 t in 2010 respectively.
