Population urbanization is closely related to carbon emission control, but the relationship between them is uncertain. Population urbanization makes carbon emit more greatly, which is the main cause of carbon emission increase. Therefore, population urbanization can also be the “key” to control carbon emission effectively. This article constructs the analysis framework of carbon emission control mechanism in the aspect of population urbanization, and identifies it preliminarily: the development of population urbanization will increase the number and scale of cities; the spatial distribution, the life and the production activities of the urbanized population con-stitute the three city depa rtments-life, traffic and production, which are also the three sources of carbon emission. It is the increase of number and scale of cities, different flow of migration to cities and the changes of the spatial distribution, the life and the production activities of the urbanized population that leads to different carbon emis-sion. This is not only the carbon emission mechanism of population urbanization, but also the clue to the scientific way to promote the low carbon of population urbanization.  相似文献

Firstly, the trend of development from Digital City to Smart City is introduced. The concept of smart city and its key supporting technologies are described as well. Then, we discuss the intrinsic meaning of Smart City: based on the basic framework established by Digital City, efficient integration of the real world and digital world through the Internet of Things and massive and complex calculations by cloud computing center provide more intelligent services for city management and public services. Furthermore, major characteristics of Smart City are summarized and several related applications are put into practice. All of those applications prove that Smart City could provide more intelligent services and securer technical support. Meanwhile, we analyze the disorganized information, security, sharing and property rights issues that still exist in the Smart City. In addition, this paper provides effective countermeasures from aspects of standards, laws, technology and applications, and makes reliable and efficient exploration for the construction of the Smart City. Finally, a prospect of promising future of Smart City is presented.  相似文献

Cities are socio-ecological systems that can, as a result of rapid social, economic or environmental changes, disasters or conflicts, slip into a state of chaos. Long-term urban sustainability is challenged by a number of worldwide trends, such as rising food and fuel prices, climate change and increasing scarcity of water. Urban resilience generally refers to the ability of a city or urban system to withstand a wide array of shocks and stresses. Enhancement of resilience is widely cited as a key goal for both adaptation and mitigation efforts in cities and ur-ban regions. Resilience is seen as a desirable property of natural and human systems in the face of a range of po-tential stresses, including weather-related hazards. The study on resilient city is almost in foreign countries, which idea is widely applied in Urban Plan and Architectural Design, but it seldom appeared in our country. The research about resilient city is most concentrated on three dimensions: environmental resilience, economical resilience and social resilience, and the social resilience get the minimum attention. Urban Agriculture is important to build re-silient city because of its multifunction. Based on this idea, this paper attempts to define the role of UA in building resilient city. In addition, this paper also devotes to analyze how UA make our city become more resilient to an-swer the potential crisis in emergency or sudden events and normal circumstance, such as climate change and oil peak.  相似文献

In the process of urban-rural integration, rural areas near big cities are facing or experiencing unprecedented evolvement and transformation, which lead to the gradual upgrading of agriculture from traditional agriculture to urban agriculture. Moreover, urban agriculture appears as a new industry to merge into urban economic and modern life. There is strong interaction between urban agriculture and village construction, which could promote urban-rural integration and becomes the inevitable choice of agricultural development trend in urban areas. This paper firstly redefines urban agricultural concept and views the unban agriculture with dynamic perspective and puts it under the overall urban-rural system instead of the original structure (studying city only under the background of the city, while studying country only within the background of the country). Secondly, the paper discusses the relationship between urban agriculture and village construction and the necessity of developing urban agriculture. Thirdly, it summarizes urban agricultural development pattern and path in the process of ur-ban-rural integration. At last, the practice of urban agriculture development in Beijing, Shanghai and Chengdu is introduced to provide some experience and advice in this field.  相似文献

Based on the data of China Statistical Yearbook, this thesis analyzes and compares the economic situation and developmental dynamics of provincial administrative regions. On the basis of the available data, this paper unfolds the national economic situation by the total retail sales of social consuming goods and saving deposits. As the economic situation is largely depends on productivity, the paper further observes the productivity of different regions through local total output value, industrial output value and grain yield. It also observes the production environment from the perspectives of new fixed assets investment on infrastructure, energy consumption, gross import and export commodities, land transportation volume, water transportation volume and passenger cycle. For the convenience of regional comparison, the indicator is acquired by local per capita dividing national per capita. In order to observe the evolution dynamics, all these indicators make use of the data from any available year so as to show the rich information of the systematic regional pattern of the nation’s economy. The above 11 indicators form an eleventh dimensional space, which observes the differences in the degree of development between different regions. It also observes the different structures of different economic entities, which shows the main features of China’s economy in geographical distribution: Southern agriculture region and northern mining region provide the basic resources and cheap labor forces to support the running of coastal industry; while the products of the coastal industrial zone are exported through coastal port cities.  相似文献

Based on the analysis of carbon emission sources in steel manufacturing process, the status quo and the characteristics of GHG emission in the steel industry are analyzed. It is concluded that CO2 is the major greenhouse gas that contributes to greenhouse effect and it is mainly caused by energy consumption. As there are many CO2 emission calculation methods for the steel industry or plants, involving aspects such as direct emission, indirect emission, and credits, it should be noted that it makes little sense to compare CO2 emission indexes from different sources. Based on the estimation of direct CO2 emissions in the steel industry in China from 1991 to 2008, it is indicated that the specific direct CO2 emission per ton steel is de-creased from 3.29t in 1991 to 1.92t in 2008, which shows that energy-saving and emission reduction in the Chinese steel industry has made significant progress. Besides, this paper introduces international develop-ments in low carbon technologies, such as ULCOS, COURSE 50, etc.. Meanwhile, the low-carbon technolo-gies, mainly the secondary energy utilization technologies, and CO2 emission reduction potential during the “Twelfth Five-year Plan” in China are analyzed. This paper predicts that, compared with the specific CO2 emission per ton steel in 2005, the figure in 2015 will be reduced by 104.01kg. Finally, GHG emission re-duction measures and roadmap in Chinese steel industry are put forward, and some policies are suggested.  相似文献
