Research on the path of low-carbon city system construction mode based on energy consumption per unit output value method

In recent years, low-carbon research has become a research hotspot in urban system construction. Cities consume a large amount of carbon-based energy and are an important research object in low-carbon research. This paper first quantitatively analyzes the correlation between the three major industrial structures and the industrial energy consumption structure. At the same time, it studies the substitution of multiple energy sources, and obtains the mechanism of action of the low-carbon city system. Through the collection and analysis of data, the necessity of improving energy efficiency for the development of low-carbon cities has been proven. On the basis of this data analysis, this paper uses the method of energy consumption per unit output value to build a scenario analysis model of urban carbon emissions, puts forward four models of low-carbon urban system construction in terms of material flow, and gives the path planning and selection of low-carbon urban system construction.
