| 为研究农业技术水平和自然禀赋对农业碳排放和碳汇的影响，通过修正后的农业碳补偿测算方法，计算得到2007—2016年长江经济带各省（市）的农业碳补偿额并进行对比分析。结果表明：江西和湖南的农业碳排放冗余量均为零值，农业技术水平较高，浙江和云南的农业碳排放冗余量较高，均值分别达到237.18万t和175.13万t，农业技术水平落后；浙江、江西、四川和云南的年均调整系数小于1，农业自然资源禀赋高于长江经济带的整体水平；修正后浙江和云南的碳补偿额由正数变为负数，表明这两个省从碳受偿地区变为碳支付地区，上海、江苏、安徽、湖北、湖南、重庆、贵州农业碳补偿额比修正前有所增加，江西和四川农业碳补偿额则比修正前减少。长江经济带各省域应加强农业自然禀赋的建设，提高生态背景值，增强其农业生态系统的碳汇功能，加快实现长江经济带生态补偿公平价值，并提升生态资源利用的地区公平性。 |

| In order to consider the impact of agricultural technology levels and natural endowment on agricultural carbon emissions and carbon sinks, this paper revised the method for calculating agricultural carbon compensation, obtaining the agricultural carbon compensation of each province(cities) in the Yangtze River economic belt from 2007 to 2016 and conducted a comparative analysis. The results showed:both Jiangxi and Hunan's agricultural carbon emission redundancy were zero, and their agricultural technology level was relatively high, while Zhejiang and Yunnan had high agricultural carbon emission redundancy, with average values reaching 2.371 8 and 1.751 3 million tons respectively, and their levels of agricultural technology were low. The average annual adjustment coefficient of Zhejiang, Jiangxi, Sichuan and Yunnan was less than 1; the endowment of agricultural natural resources in these areas was higher than the overall level in the Yangtze River economic belt. After revision, the carbon offsets of Zhejiang and Yunnan changed from positive to negative, indicating that these two provinces had changed from carbon compensation areas to carbon payment areas. The amount of agricultural carbon compensation in Shanghai, Jiangsu, Anhui, Hubei, Hunan, Chongqing and Guizhou increased compared with that before revision, while the amount of agricultural carbon compensation in Jiangxi and Sichuan decreased compared with that before revision. The provinces of the Yangtze River economic belt should strengthen the construction of agricultural natural endowment, strengthen the value of the ecological background, enhance the carbon sink function of agricultural ecosystems, and improve the fairness of agricultural carbon compensation standards. |
