基于清单核算法的社区碳排放时空分布特征

Spatial and Temporal Distribution Characteristics of Community Carbon Emissions Based on Inventory Accounting Method

基于IPCC清单编制法,对四川雅安某社区2015~2017年的碳排放进行核算,并通过可视化表达,分析其时空分布特征,以期为促进社区节能减排,推进低碳发展提供建议。结果发现该社区2015~2017年碳排放总量分别为13 726 t、19 857 t以及25 353 t,呈现出显著上升趋势,但各贡献源的排放各有不同,电力使用贡献最大。不同功能建筑之间的碳排放强度也存在明显差异,高层住宅>商铺>低层住宅>企事业单位。

Based on the IPCC inventory compilation method,this paper calculated the carbon emissions of a community in Ya'an,Sichuan province from 2015 to 2017,and analyzed its spatial and temporal distribution characteristics through visual expression,in order to provide Suggestions for promoting community energy conservation and emission reduction and promoting low-carbon development.The results showed that the total carbon emissions of the community from 2015 to 2017 were 13726 t,19857 t and 25353 t,respectively,showing a significant upward trend.However,the emission of each contributing sources vary significantly,and electricity consumption contributed the most carbon emissions.There are also significant differences in carbon emission intensity between buildings with different functions.High-rise residential buildings>shops>low-rise residential buildings>enterprises and institutions.
