湖南低碳农业发展的生态效应及对策研究

Ecological Effects and Countermeasures of Low Carbon Agriculture Development in Hunan Province

摘要: 应对气候变暖、确保能源安全、保护资源环境的必然选择是逐步降低经济增长过程中的碳排放。文章将农业碳汇视为期望产出引入到低碳农业经济学分析框架，以2007~2017年中部六省低碳农业指标的面板数据为样本，运用碳计量模型评估湖南低碳农业发展绩效，实证结果表明，湖南在农业生产过程中保持了良好的净碳汇效应，低碳农业发展的生态效应良好；净碳汇虽存在波动状态，但整体呈增长趋势，实现了低碳农业发展绩效的提升；低碳农业发展意识逐步被接受与认可，相关低碳政策落实比较到位；但是区域个体差异显著，河南净碳汇量最大，增幅最低，湖南净碳汇量第三，年增长率6.9%，位于中下游。

Abstract: The inevitable choice to deal with climate warming, ensure energy security and protect resources and environment is to gradually reduce carbon emissions in the process of economic growth. This paper takes agricultural carbon sink as expected output and introduces it into the low-carbon agri-cultural economic analysis framework. Taking the panel data of low-carbon agriculture indicators of six provinces in Central China from 2007 to 2017 as samples, this paper uses carbon econometric model to evaluate the development performance of low-carbon agriculture in Hunan Province. The empirical results show that Hunan maintains a good net carbon sink effect in the process of agri-cultural production, and the ecological effect of low-carbon agricultural development is good; alt-hough the net carbon sink fluctuated, it showed an increasing trend as a whole, which improved the development performance of low-carbon agriculture; the awareness of low-carbon agricultural de-velopment was gradually accepted and recognized, and the implementation of relevant low-carbon policies was in place; however, there were significant differences among regions, with Henan prov-ince having the largest net carbon sink and the lowest growth rate, and Hunan Province with an annual growth rate of 6.9%.
