"双碳"目标下河北省农业生态效率时空演进特征及影响因素
Characteristics of spatial and temporal evolution of agriculture eco-efficiency and the influencing factors in Hebei Province under the goal of"carbon peaking and carbon neutrality"
摘要
Abstract
Under the strategy of"carbon peaking and carbon neutrality",the agricultural sector will undergo extensive and profound systemic changes.Agricultural development in Hebei Province has long been in a situation of tight ecological environment and natural resources,and studying the spatial differences in agriculture eco-efficiency and analysis of the influencing factors in this region can be a reference for other regions.An evaluation index system was constructed based on the panel data of 11 city from 2002 to 2021,and the global super-efficiency SBM model with non-expected output was used to measure the level of agriculture eco-efficiency in Hebei Province.Visual presentation of the spatio-temporal distribution pattern and the analysis of the evolution trend were carried out using Arc GIS,and the parametric optimal geodetector was used to identify the main factors affecting the spatial differentiation of agriculture eco-efficiency and the main influencing factors as well as the interactions among the factors.From 2002 to 2021,the agriculture eco-efficiency of Hebei Province has shown a rising trend of fluctuation in stages,with the efficiency value increasing from 0.63 in 2002 to 0.94 in 2021.There were significant differences in the evolution of the efficiency curves of cities,and the spatial patterns were markedly different,with the differences between the eastern and western regions gradually narrowing and those between the"high in the north and low in the south"being very prominent.Farmers income level,agricultural labor productivity,agricultural machinery density,crop cultivation structure,and urbanization rate were the dominant factors affecting the spatial differentiation,and the explanatory power of each factor and their interactions showed fluctuating and changing trends over time.In the future,there is a need to explore the priorities for agricultural development in different regions in light of local conditions,and to resolve the imbalance in development between the"high north and low south".At the same time,we are accelerating the development of new productive forces in the agricultural sector,finding an effective match with the key factors affecting agriculture eco-efficiency and improving it.关键词
