文档介绍：11 “低碳生态城市”——全球气候变化影响下未来城市转型发展的战略选择 Low-carbon Eco-city —— The Strategic Choice Of Future Cities For Transformational Development Under The Influence Of Global Climate Change 中国城市科学研究会李迅、刘琰 Chinese Society for Urban Studies Li xun \Liuyan 20 10 -03- 25 2 、碳排放与城市化关系 relationship between global climate change, carbon emissions and urbanization 3. 中国向低碳生态城市转型发展的愿景设计 4. 中国低碳生态城市发展的行动路线图设计 2 、碳排放与城市化关系 The relationship between global climate change, carbon emissions and urbanization 3 ?(1)气候变化是 21 世纪人类面临的最复杂挑战之一? Climate change is one of the plex challenges in the 21st century . ?(2)如何应对气候变化成为全球关注的焦点? How to deal with climate change has e the focus of global concern. ?(3)形势分析——从科学共识到全球行动? Situation analysis —— from scientific consensus to global action. ?(4)碳排放是影响气候变化的重要因素? Carbon emissions is an important factor that impact on climate change. ?(5)碳排放与城市化过程相互交织、相互影响? Carbon emissions and urbanization intertwine and affect each other. 4 气候变暖与温室气体排放关系密切 Climate warming and greenhouse gas emissions are closely related. ?1970 年至 2004 年,全球温室气体排放量增加了 70% 。?2006 年,中国的二氧化碳排放量达 5800 百万吨,超过美国 8% ,代替美国成为世界最大的温室气体排放国。?温室气体的排放与工业化、城镇化进程密切相关,与城镇化的模式密切相关。 5 ?城市既是能源资源消耗的主体? Cities are the main consumption of energy resource. ?2006 年,我国 287 个地级以上城市市区的能源消费量占全国总能耗的 % ,二氧化碳排放量占全国总排放量的 % 。?城市也是节能减排的重点? Cities are the focus of energy-saving and emission reduction. ?中国处于城镇化快速发展时期,未来 20 年城镇化水平年均提高 ~1个百分点左右。中国城乡人口规模与城镇化率 6 各国能源消耗比较?我国人均能耗较少,但人口基数大,增长快,已引起全球关注。? China's per capita energy consumption is relatively less, but large population, fast growth has attracted global attention. ?由于工业化过程和转移排放,我国将较长时间成为 CO2 排放的世界第一国。? As the process of industrialization and the transfer of emissions, China will be the first country of carbon dioxide emissions in a long time. 7 、碳排放与城市化关系 trend of urban transformational development under the influence of climate change 3. 中国向低碳生态城市转型发展的愿景设计
