| 以贵州省2010 年土地覆被类型数据为基础，采用碳排放模型分析不同土地利用方式下的碳排放量，并估算生态补偿效益。研究结果显示：（1）与2005--2007 年平均水平比较，2010年贵州碳排放总量和碳排放强度分别提高了34.7%和34.5%。（2）贵州省碳汇总量远高于碳排放总量，生态补偿值为-1 390.11*108元，固碳作用明显。（3）省内各地区间碳排放水平不均匀，碳排放总量最大的为贵阳市，碳排放强度最高的为六盘水市，通过分析可以看出，碳排放量和强度与产业结构紧密相关，尤其是工业所占比重。在今后的发展过程中，贵州省应进一步优化产业结构，降低能源消耗，充分发挥其生态固碳的作用，其他碳源省份应对贵州予以一定的生态补偿。 |

| This paper applied carbon emission models to analyze the carbon emissions under different land This paper applied carbon emission models to analyze the carbon emissions under different land use types and estimate ecological compensation based on the land use data of Guizhou province in 2010. The results showed that: (1) Compared with the average level between 2005 and 2007, the overall carbon emission and carbon emission intensity of Guizhou in 2010 increased by 34.7% and 34.5% respectively. (2)The total carbon sink exceeded the overall carbon emission, and the compensation price was -1 390.11*108 yuan. Therefore, the carbon fixation was obvious. (3)The carbon emission level was uneven in all the prefectures. Guiyang had the maximum overall carbon emission and Liupanshui had the highest carbon emission intensity. By analysis, it could be seen that total carbon emission
and carbon emission intensity were closely related with industrial structure, especially the percentage of industry. In future development,Guizhou should optimize industrial structure, reduce energy consumption and play the role of carbon fixation. Other carbon resource provinces should offer some ecological compensation to Guizhou. |
