碳中和目标下淮河生态经济带土地利用碳排放效率评价及影响因素
Evaluation of carbon emission efficiency of land use and influencing factors in the Huaihe River Ecologi-cal Economic Belt under carbon neutrality target
摘要
Abstract
The purpose of this study is to explore the influencing factors of carbon emission efficiency of land use in the Huaihe Eco-economic Belt and provide theoretical reference and empirical evidence for accelerating the green transformation of land use in the Huaihe Eco-economic Belt and helping achieve the goal of carbon neutrality.The methods of literature research,Super effi-cient SBM-GML model and standard deviation ellipse were employed.The research findings show that:the carbon sink in the Huaihe Eco-economic Belt is relatively stable,while the net carbon emissions are on the rise,with the construction land being the main source of carbon emissions;the overall level of carbon emission efficiency from land use is relatively low,showing a trend of first decreasing and then increasing,spatially dispersed in southeast-northwest direction and concentrated in northeast-southwest direction,and the direction has increased,the GML index showed a"rise-fall-rise"trend,and the decomposition showed that technological efficiency is the main reason for the increase in GML index;Environmental regulations,economic development,population density,and green technological progress have a significant impact on improving the carbon emission efficiency of land use,while urbanization and industrial structure have a significant negative impact.关键词
