Using energy consumption and land use data of each region of China in 2007, this paper established carbon emission and carbon footprint model based on energy consumption,and estimated the carbon emission amount of fossil energy and rural biomass energy of dif-ferent regions of China in 2007. Through matching the energy consumption items with indus-industrial-commercial space, transportation industrial space, fishery and water conservancy space, and other industrial space. Then the author analyzed the carbon emission intensity and carbon footprint of each industrial space. Finally, advices of decreasing industrial carbon footprint and optimizing industrial space pattern were put forward. The main conclusions are as following: (1) Total amount of carbon emission from energy consumption of China in 2007 was about 1.65 GtC, in which the proportion of carbon emission from fossil energy was 89%.(2) Carbon emission intensity of industrial space of China in 2007 was 1.98 t/hm<,2>, in which,dustrial space was 55.16 t/hm<,2> and 49.65 t/hm<,2> respectively, they were high-carbon-emission industrial spaces among others. (3) Carbon footprint caused by industrial activities of China in 2007 was 522.34x10<'>6 hm<,2>, which brought about ecological deficit of 28.69x10<'6> hm<,2>, which means that the productive lands were not sufficient to compensate for carbon footprint of industrial activities, and the compensating rate was 94.5%. As to the regional carbon footprint,several regions have ecological profit while others have not. In general, the present ecologi-cal deficit caused by industrial activities was small in 2007. (4) Per unit area carbon footprint trial-commercial space was the highest (17.5 hm<'2>/hm<'2>). The per unit area carbon footprint of different industrial spaces all presented a declining trend from east to west of China. 相似文献

城市功能的充分实现与城市建设用地规模及城市用地结构配置的合理性密切相关,日益增长的对美好生活的需要离不开对于更加完善的建设用地需求格局、结构等影响特征的关注。人类发展指数能够从经济发展、生命健康和社会进步多个维度较为全面地衡量国家和地区发展水平。从2015年全球151个国家的人类发展指数和城市人均建设用地数据来看,人类发展指数的提高与城市建设用地的增长具有正相关关系,中国的城市建设用地仍具有一定的增长潜力。结合发达地区的城市治理政策以及城市规划理念和模式,认为中国目前需要调整用地结构、增加民生用地供给,在促进城市经济发展的同时体现更多的宜居性,从而促进社会经济整体水平的提升。 相似文献
