Abstract: After the Paris Agreement, low-carbon development has become an inevitable choice for countries around the world to cope with climate change. At present, most county economies in China are still in the middle stage of industrialization, and the potential of low-carbon development is huge and the demand is urgent. Therefore, compared with existing studies on low-carbon spatial planning at home and abroad, which mainly focus on urban areas, it is of more practical significance to carry out measurement analysis of carbon income and expenditure at the county level to promote national low-carbon development.The paper took Huantai County, an economically developed region, as the research object, on the basis of integrating multiple data sources, constructed a carbon balance zoning method, and calculated the energy consumption and emission, indirect carbon emission of household consumption and total carbon sink in 2016. The main conclusions are as follows:1) In 2016, the total carbon emission of Huantai County was 5.159 million tons, and the spatial pattern of carbon emission showed a dual center structure with Suo town, Guoli town and Tangshan town as the main center and Maqiao town as the sub center. 2) In 2016, the total amount of carbon sink in Huantai County was 234900 tons, and the spatial pattern of carbon sink showed the characteristics of "high in the northeast and low in the southwest" dominated by Jingjia town and Qifeng town. 3) Taking villages and towns as the basic spatial unit, Huantai County is divided into four types of carbon balance zones:carbon intensity control zone, low-carbon optimization zone, carbon balance zone and carbon sink function zone. On this basis, the paper put forward the county low-carbon spatial planning guidance countermeasures based on the optimization of carbon balance zoning, and explored the effective ways and methods for the county low-carbon development from the perspective of spatial layout.
