| description | [Objective] Optimizing the carbon budget measurement and efficiency of farmland production based on the “natural-anthropogenic” dual structure, and exploring its spatial and temporal evolution characteristics and related influencing factors can provide theoretical and practical bases for the realization of carbon sink increase and emission reduction in farmland. [Methods] This study comprehensively calculated the farmland carbon budget of 30 provinces of China from 2005 to 2021 from the aspects of natural ecosystem carbon budget and anthropogenic carbon emissions. The farmland carbon efficiency was evaluated by using the super-efficiency SBM-GML model considering the input of natural factors, and the influencing factors of carbon efficiency change were analyzed through the spatial lag model. [Results] The research showed that: (1) China's farmland ecosystem carbon absorption continued to grow. Anthropogenic carbon emissions increased first and then decreased with 2017 as the turning point. The carbon emissions and absorption in the Northeast Plain, the middle and lower reaches of the Yangtze River, the Huang-Huai-Hai Plain, and the northern arid and semiarid areas were both high. (2) In 2021, the national farmland carbon efficiency value was 0.835, and the efficiency values of 16 provinces were greater than 1. The overall efficiency level of the Northeast Plain, Huang-Huai-Hai Plain, South China, and Qinghai Plateau was high, and the overall efficiency level of the Loess Plateau was low. (3) The difference in technical efficiency was the main reason for the difference in carbon efficiency. The improvement of carbon efficiency in Huang-Huai-Hai Plain, Yunnan-Guizhou Plateau, South China and Qinghai Plateau was due to the dual contribution of technical efficiency improvement and technological progress. (4) Industrial agglomeration and natural hazard-related disasters had a negative impact on technical efficiency improvement, and technological progress, and then on carbon efficiency. Agricultural investment and labor culture could promote technical efficiency and technological progress, thus promoting carbon efficiency. Financial support for agriculture inhibited technological progress and then carbon efficiency improvement. [Conclusion] Under the “natural-anthropogenic” dual structure, the carbon absorption capacity and carbon efficiency of China's farmland production have been steadily improved, while the inter-regional carbon efficiency differences were still significant. We should pay attention to and standardize the management of natural resources, narrow the differences in carbon efficiency among regions, and help achieve the goal of carbon neutrality. |
