| 中文摘要: |
| 以广州市为对象，构建了城市土地利用碳源/碳汇的研究框架，测算了土地利用的碳排放量和碳吸收量，深入剖析了土地利用变化的碳排放效应。结果表明，1996—2008 年广州市土地利用的净碳排放量呈上升趋势，各区县净碳排放量的空间差异大，另外，建设用地的碳排放效应为0.03614*10^4 t/hm2。GM预测结果显示，2020 年净碳排放量明显增加，并提出了土地利用的增汇减排建议。 |
| 英文摘要: |
| The paper selected Guangzhou as research object, built the research framework of carbon source and carbon sink of land
use, and also calculated the carbon emissions and carbon uptakes of land use, analyzed the effects of land use on carbon emission indepth.The results showed that the net carbon emissions presented the rising trend from 1996 to 2008 in Guangzhou, the net carbon emissions change of each districts and countries had the features as otherness. In addition, the effect of construction land was 0.03614*10^4 tons per hectare, and the predicted results showed the net carbon emissions increased significantly in 2020. In the end, the paper put forward some suggestions which could increase the carbon uptake but reduce the carbon emission from the angle of land use optimization. |
