Parks are the main source of urban carbon emissions in China. To clarify the composition of park- level carbon emission sources or sinks is the key to carrying out research on lowcarbon pathways for parks. At present, there are no park-level carbon emission calculation-related norms or guidelines at home and abroad. Most of the research that has been carried out is to calculate and analyze the carbon emissions of a specific type of stock park, without fully considering the data availability of new parks or the adaptability of the calculation system to different types of parks. Therefore, a park-level carbon emission calculation method considering the characteristics of various types of parks is proposed. The calculation system is constructed from five dimensions,including energy activities (covering agriculture, industry, construction, transportation, tourism facilities, power infrastructure, etc.),agricultural production, industrial production, waste treatment,green plant carbon sinks. The calculation formulas for both complete data scenario and missing data scenario are respectively proposed as well. Case study shows that the proposed method is applicable to the calculation of total carbon emissions and structural analysis of various types of parks such as agricultural parks, industrial manufacturing parks, business parks, and tourism parks.
