| 摘 要： | 为全面评估农业生产的碳收支状况,并为农业碳减排提出切实可行的对策建议,采用1978─2009年的中国各种农作物产量和农业投入等统计数据,运用碳源/汇估算模型对我国农业生产碳收支进行了初步的核算和分析。结果发现,中国农业活动的碳吸收明显大于碳排放,这说明总体而言我国是农业"碳汇"区,但各省区碳收支空间差异明显,部分沿海发达地区碳排放量大,净碳汇表现为负值,这表明发达地区有较高的农业投入。因此,应重点从促进土壤固碳、改变耕作方式和施肥方式、加强土地节约集约利用等方面促进农业碳减排。 |

| Abstract: | In order to systematically assess the carbon budget of agricultural production, and to provide advices and countermeasures for carbon emission reduction in agricultural sector, using statistic data of crop yield and agricultural consumption of China from 1978─2009, this paper estimated the carbon budget of agricultural activities. The results showed that the total carbon sink, carbon emission and net carbon sink increased since 1978, and the carbon sink was obviously higher than carbon emission, which meaned that China was an agricultural "carbon sink" area. It was quite different on carbon budget among different regions. In general, the costal developed region had higher carbon emission, and the net carbon sink was negative, which indicated that the developed region had high agricultural inputs. Therefore, agricultural carbon emission reduction should be promoted through soil carbon sequestration, changing cultivated mode and fertilizing mode and saving and intensive land use. |
