东北农区农业净碳汇时空分布及驱动因素
The spatiotemporal distribution and driving factors of agricultural net carbon sink in northeast agricultural areas
摘要
Abstract
Agriculture has dual roles as a carbon source and a carbon sink and is an important component of China's goal of achieving carbon peak and carbon neutrality.In terms of fairness in agricultural carbon emissions,it is of immense importance to comprehensively control agricultural carbon sources and sinks and clarify the driving factors of agricultural net carbon sinks to achieve low-carbon agricultural development in northeast agricultural areas.Based on social and economic data and agricultural production data from cities in Heilongjiang Province from 2000 to 2020,we explored the equity characteristics of regional agricultural carbon emissions and the driving factors of net carbon sinks using ecological carrying capacity models,economic efficiency models,and geographical detectors.The results showed that the total amount of agricultural net carbon sink in Heilongjiang Province demonstrated a fluctuating upward trend,from 1.21×107 t in 2000 to 4.02×107 t in 2020.Qiqihar,Suihua,and Harbin had the highest net carbon sequestration in agriculture,with the three cities accounting for over 51%of the carbon sequestration in Heilongjiang Province.In terms of agricultural carbon emission equity zoning,the dual high zone primarily concentrated toward Harbin,Heihe,and Suihua in the south and central regions,whereas the dual low zone gradually concentrated toward Jixi,Shuangyashan,and Hegang in the east.The dual low zone is gradually developing toward an economic high-value zone,ecological high-value zone,and dual high zone;however,the gap between different cities is still significant.The area of arable land area and the mechanization level are the main driving factors for the spatial differentiation of agricultural net carbon sinks.The results of interaction detection show that the interaction between arable land area and mechanization level has the strongest correlation with other factors.The net carbon sink is most affected by the interaction between the mechanization and urbanization levels.Heilongjiang Province must develop differentiated green agriculture control measures based on the specific situation of each region to promote sustainable agriculture development in northeast agricultural areas.关键词
