中文摘要：

旅游者的实践参与是发展低碳旅游的关键。以苏南古镇周庄、锦溪、千灯为研究案例地，分析2006--2015年古镇旅游者二氧化碳排放量现状，发现碳排放量总体呈现逐年增加趋势，其中2015年周庄、锦溪、千灯古镇旅游者总碳排放量分别达到67310．68kg、19259．23kg、18995．67kg。调查古镇旅游者低碳旅游行为，发现古镇旅游者在自带旅游生活用品、植树造绿、低碳餐饮、低碳住宿、减少棉织品洗涤、低碳交通等方面做得还不够。在分析研究的基础上，有针对性地提出古镇旅游者低碳旅游行为优化对策：倡导自带生活物品，减少游览中一次性用品消耗；设置旅游纪念林，引导旅游者参与古镇植树活动；提倡绿色食品，避免奢侈浪费；发展古镇特色民宿，做到低碳住宿；赠送低碳旅游纪念品，减少旅游者棉织品洗涤次数；发展公共交通，鼓励旅游者低碳出行；发展低碳智慧旅游，科学引导旅游者低碳旅游行为。

Tourist＇s participation is crucial to the development of low carbon tourism. According to the cases of the three ancient towns （Zhouzhuang, Jinxi and Qiandeng）, this paper analyzed the carbon dioxide emissions of ancient town tourists from 2006 to 2015, to find that carbon emissions showed a trend of increase year by year. The total carbon emissions of tourists in Zhouzhuang, Jinxi, Qiandeng in 2015 was 67 310.68 kg, 19 259.23 kg, 18 995.67 kg respectively. For the low carbon travel behavior of ancient town tourists, it is proved that bringing tourist supplies, planting trees, low carbon accommodation, reducing cotton washes, low- carbon transportation need to be improved. On the basis of the analysis, the research put forward the optimization countermeasures of low carbon travel behavior of ancient town tourists： To advocate carry-life products and reduce the waste of disposable goods during the tour. To set up a tourist memorial forest and guide the tourists to participate in the activities of planting trees. To promote consumption of green food and avoid food waste. To develop home-stay specialties in the ancient town and advocate low carbon hotel. To present the low carbon tourist souvenirs and reduce the cotton washes of tourists.
