考虑碳排放约束的耕地利用生态效率时空差异与影响因素分析
Spatial-temporal differences and influencing factors of eco-efficiency of cultivated land use considering carbon emission constraints
摘要
Abstract
To provide reference for ensuring food security,promoting low-carbon agricultural development,promoting green and high-quality agricultural development and regional coordinated development in the black soil region of Northeast China.Using carbon emissions from farming process as the constraint of non-expected output,this paper used the ultra-efficiency EBM model to effectively measure the ecological efficiency of cultivated land use in the Northeast black soil region from 2007 to 2021.Further,this paper used Malmquist index model and Tobit regression model to explore the spatial-temporal differences and influencing factors of ecological effi-ciency of cultivated land use in Northeast black soil region considering carbon emission constraints.The results showed that:①Consider-ing carbon emission constraints,the ecological efficiency of cultivated land use in Northeast black soil region showed an overall"N"pattern of first increasing,then decreasing and then increasing.Among the four provinces in Northeast black soil region,Heilongjiang Province was the only relatively effective province,and 72.4％of the 29 prefecture-level cities did not reach the effective state.②The ecological efficiency loss of cultivated land use under carbon emission constraints was caused by input,redundancy of undesired output and insufficiency of expected output.Meanwhile,technological progress had a more significant impact on productivity.③The ecological efficiency of cultivated land use in Northeast black soil region was significantly affected by resource endowment,environmental regula-tion level and government support.On the above,in order to improve the ecological efficiency of cultivated land utilization in black soil area,the natural,production and ecological characteristics of black land should be considered,the input structure should be optimized,the agricultural modernization level should be improved,and the development plan of sustainable cultivated land utilization and green carbon reduction should be formulated.关键词
