摘　　要：以东北黑土区土地利用碳排放为研究对象,基于2000~2020年土地利用和能源消耗数据,分析不同土地利用类型碳排放量的变化情况并预测区域碳排放。结果表明,2000~2020年东北黑土区土地利用碳排放量持续增加,从2000年152.44×10^(4)t到2020年253.22×10^(4)t,年变化趋势明显。碳排放方面,耕地与土地利用碳排放的关联度最高是最主要的碳源,占总碳源的90%左右;碳吸收方面,林地对碳汇的贡献率最大,占总碳汇的96%以上。东北黑土区的用地类型与碳排放间的关联度依次为耕地>林地>建设用地>未利用地>草地>水域。预计2030年净碳排放量将达到300.62×10^(4)t。This study focused on the carbon emissions from land use in the black soil area of Northeast China.Based on land use and energy consumption data from 2000 to 2020,it analyzed the changes in carbon emissions from different land use types and predicted regional carbon emissions.The results showed that:from 2000 to 2020,the carbon emissions from land use in the black soil area of Northeast China continued to increase,from 152.44×10^(4) t in 2000 to 253.22×10^(4) t in 2020,with a clear annual trend of change.In terms of carbon emissions,the correlation between arable land and land use carbon emissions was the highest,making it the main carbon source,accounting for about 90%of the total carbon source in terms of carbon absorption,forest land had the highest contribution rate to carbon sink,accounting for over 96%of the total carbon sink.The correlation between land use types and carbon emissions in the black soil area of Northeast China was in the order of cultivated land>forest land>construction land>unused land>grassland>water area.It expected that the net carbon emissions would reach 300.62×10^(4) t by 2030.
