Calculation and analysis of greenhouse gas emissions in plain rural areas of Hebei Province based on survey data
In this paper,rural greenhouse gas(GHG)emission pathways are divided into 4 categories:agricultural production,animal husbandry,waste treatment,and energy consumption.The GHG emission calculation methods of each pathway were proposed based on the Guidelines for Provincial GHG Emission Inventories and the IPCC carbon emission inventory compilation method.Accounting was conducted for 316 villages in the plain area of Hebei Province.Utilizing the K-means clustering algorithm,all villages were divided into three categories according to the CO2 equivalent emissions from each pathway,and the GHG emission characteristics of each type were analyzed.The results indicate that in the investigated rural areas,CO2 emissions mainly came from energy consumption,accounting for 70.9%to 75.5%;CH4 emissions mainly came from animal husbandry and waste treatment,totaling 73.2%to 94.7%;N2O emissions predominantly arise from agricultural production,accounting for 52.3%to 84.7%.Energy consumption was the main source of CO2 equivalent emissions,followed by agricultural production and animal husbandry.Energy conservation remains an effective approach for reducing carbon emissions in rural areas.At the same time,attention should also be paid to the management of farmland and livestock,and improving the collection and standardized treatment of garbage and sewage.
