摘要
中国作为世界能源消费大国,同时也是农业大国,其生物质能源利用在农村能源消费构成中占据很大比重。文章采用排放因子法对2010年中国各省(市\区)农村生物质能源利用的CO2排放量进行了估算,利用ArcGIS对估算结果进行空间分析,运用空间统计方法,在Geoda平台上分析各地区碳排放量的空间自相关性。结果表明:秸秆和薪柴的利用对农村生物能源利用的CO2排放量有重要贡献,沼气所占比例较小。在空间分布特征上,生物质能源利用的CO2排放量呈现出中西高、东南偏低的分布特征。
As one of the biggest energy consumers of the world, China is also a large agricultural country, whose bioenergy occupies a larger proportion in rural energy system. Emission factor method is applied in thi＇s study to estimate CO2 emission by rural bioenergy utilization of each province （municipality/autonomous region） in 2010. Tool of Arc GIS is used to make spatial analy- sis of the estimation results. By the method of spatial statistics, researches on the spatial autocor- relations of regional carbon emission are conducted with application of Geoda software. It is con- cluded that CO2 emissions by bioenergy utilization are mainly contributed by straw and firewood, with a smaller proportion in biogas aspects. The total emissions show the distribution characteris- tic is high in the central and southwest area, and low in the southern and southeastern areas.
