Climate change, greenhouse gas emissions, is the common responsibility of mankind to promote the development ,Promote urban development is the inhibition of carbon dioxide emissions of an important means of uncontrolled governments around the world has already reached a consensus. Currently, the increasingly wide range of low carbon development, covering areas such as low-carbon economy, low carbon transport, low-carbon industries, low-carbon technologies, low carbon buildings, etc. City of resources, energy consumption, carbon emissions concentration region, Low-carbon city development is to be concerned about. As a developing country, In recent years, urban development Accelerated, Therefore, Therefore, the study of Low-carbon city development, Not only theoretical value and practical significance.The proposed low-carbon city development reflects the changing pattern of human social development and optimization. In the article, first of all, the construction of low-carbon urban basic research conducted, Pointed out that the traditional process of urbanization and the relationship between global climate change, Proposed to accelerate the transformation of the mode of economic development, Promote the transformation of low- carbon city development,And affirmed the possibility of achieving low-carbon city. That "carbon reduction" is not carbon transfer between the various areas of, Is the absolute total carbon emissions reduction, Construction of low-carbon city is the city’s fundamental approach to achieve sustainable development. In recent years, Home and abroad for the construction of low-carbon urban theory and practice are different levels of exploration, Theoretical research focuses on carbon emissions city structure,urban system design and carbon emissions, urban planning and carbon emissions, low carbon construction urban development model, the key areas to reduce carbon emissions, etc. Practice in low-carbon city, Copenhagen, Berkeley, Freiburg, Tokyo, china baoding set up a typical. Explore different low-carbon city development model Successfully.In the article, analysis of the city the main factors of carbon emissions, Including urban industrial carbon sources, urban mobile carbon source, carbon source urban architecture, urban households carbon, carbon sequestration and other urban greening, Different types of city characteristics should be carried out against their respective areas of focus emission reduction activities. For example, the Industrial Cities and Resource-based cities should be particular emphasis on resource-based low-carbon industries to create, promote the use of low-carbon technologies, optimization of industrial structure; low-carbon transport should be particular emphasis on Integrated urban, low-carbon buildings to build, promote green travel, reduce the energy consumption of urban buildings; Tourist city should focus on the protection of urban natural ecological landscape, increase the green carbon sinks, the establishment of urban green space system, reduce urban heat island effect.Comprehensive Construction of basic theoretical research on low-carbon city, low-carbon urban practices research, analysis of urban carbon emissions and carbon factors in key areas of urban construction, Article that, Low-carbon development path planning of urban construction from two angles and Countermeasures, Top-down, public opinion first, people to participate, Build a low carbon city development support and security system. By strengthening the capacity of cities to address climate change, the establishment of low-carbon city index system of evaluation and assessment, improve the urban management system and operational mechanism, optimize the structure of urban spatial planning ways to support low-carbon city development, the formation of government guidance, market-driven, public participate in the pattern.Urban development of low carbon path and Countermeasures made of, the article under the urban area of xiacheng Hangzhou, an empirical study.xiacheng is National Sustainable Development Experimental Zone, Well-developed tertiary industry and services, After preliminary calculations, the following areas of urban transportation and building more carbon emissions, the region accounted for 71.86% of total carbon emissions, industrial,and each household carbon emissions by 8.6% and 15.15%. Feature for the xiacheng, combined with the construction of low-carbon city by the path and measures, the paper proposes a low-carbon city under the city’s method of creating an empirical analysis for the low-carbon urban theory provides support for construction of low-carbon city in China and provide a realistic basis.
