Climate change has brought challenges to the construction of human settlements. Cities are not only the gathering place for development, but also the key to mitigating carbon emissions. The current urban planning thinking mode has begun to shift to low-carbon ecologicalization. Low-carbon urban planning theory and construction practice have become the focus of attention of the international community in many urban issues. Its core idea is to transform the traditional way of urban development, develop a low-carbon economy and build a low-carbon life through the low-carbon transformation planning layout of urban space and the low-carbon industrial system. As the largest carbon source and the region with the greatest emission reduction potential, cities urgently need to transform their production and lifestyles into renewable energy and circular economy in an all-round way. As a city planning that has a strong guiding and controlling role in urban development, it also plays an important role in the transformation process. Based on the analysis of the low-carbon city planning and construction of Xi'an, Shaanxi Province, Xi'an has the following characteristics: As a northwestern industrial base, the main industrial pillar of Xi'an is the secondary industry, and the industry will continue to be occupied in the development of Xi'an. Since Xi'an's main pillar industries are petrochemicals, automobile manufacturing, metallurgy (mainly steel), and electricity, carbon dioxide emissions have seriously exceeded the standard. As a city along the river, Xi'an has abundant water resources and long and cold winters. This paper analyzes the data of Xi'an for ten years, analyzes and predicts the carbon dioxide emissions of Xi'an, and puts forward feasible low-carbon city planning and construction policies and recommendations. We summarize and analyze the existing theories, examples and research status of low-carbon city planning, and extract analysis methods and planning research theories from them. We establish urban low-carbon models and evaluation indicators to analyze and forecast Xi'an's carbon dioxide emissions from the aspects of low-carbon energy and economy, low-carbon space and layout, low-carbon transportation and transportation, low-carbon communities and buildings, low-carbon emissions and treatment, and low-carbon policies and management. |
