摘要
随着绿色低碳发展要求的不断提高,推进符合中国具体国情的低碳农业迫在眉睫。鉴于这种紧迫性,中国农业系统的非二氧化碳温室气体(GHG)排放核算仍处于不断研究和完善的过程中。因此,本文基于碳排放系数法,对 1995 至 2021 年中国西南地区农业非二氧化碳温室气体排放量进行了核算。此外,我们还利用人口、富裕程度和技术回归随机影响模型(STIRPAT)和 Tapio 模型,探讨了驱动因素的影响程度以及与经济发展的关系。我们观察到西南地区农业产生的非二氧化碳温室气体排放量总体呈先增后减的趋势,中部较高,东部和西部较低。经济、人口、结构和技术水平对不同省份的影响程度不同,有利于各地区制定有针对性的农业规划政策。在研究期间的大部分时间里,经济增长与温室气体排放之间存在或弱或强的脱钩现象。最后,提出了促进西南地区低碳农业发展的建议,为明确农业系统的温室气体贡献提供了数据库和政策支持。
Driving Factors and Decoupling Effects of Non-CO2 Greenhouse Gas Emissions from Agriculture in Southwest China
In light of the growing demand for green and low-carbon development, the advancement of low-carbon agriculture in alignment with China’s specific national circumstances is imminent. Given this urgency, the accounting of non-CO2 greenhouse gas (GHG) emissions in China’s agricultural system is still in the process of continuous research and improvement. Therefore, in this paper, we present an account of agricultural non-CO2 GHG emissions in Southwest China from 1995 to 2021, based on the carbon emission coefficient method. Furthermore, we explore the extent of the influence of the drivers and the relationship with economic development, utilizing the Stochastic Impact of Regression of Population, Affluence, and Technology (STIRPAT) model and the Tapio model. We observe a general trend of increasing and then decreasing non-CO2 GHG emissions from agriculture in the Southwest region, with a pattern of higher in the center and lower in the east and west. Economic, demographic, structural, and technological levels show different degrees of impact in different provinces, favoring the development of targeted agricultural planning policies in each region. For the majority of the study period, there was a weak or strong decoupling between economic growth and GHG emissions. Finally, recommendations are made to promote low-carbon agricultural development in Southwest China, providing a database and policy support to clarify the GHG contribution of the agricultural system.
