Exploring the Spatial Patterns and Driving Mechanisms of Farmland Spatial Transition in the Yangtze River Economic Belt
The purposes of this study are to clarify the connotations of farmland spatial transition,to identify its spatial patterns in the Yangtze River Economic Belt,to reveal the driving mechanisms,and to provide the references for the rational farmland use.The research methods include entropy,spatial autocorrelation analysis,spatiotemporal geographic weighted regression model and mediating effect model.The research results show that:1)the overall level of farmland spatial transition in the Yangtze River Economic Belt exhibits a spatial pattern characterized as"strong in the east and west,weak in the center."Over time,the condition shows an improving trend.2)Population and economic factors are the decisive factors influencing farmland spatial transition.3)The majority of the effects of the driving factors on the farmland spatial transition are direct,whereas the effects of agricultural yields and population urbanization rates are indirect.4)During the process of farmland spatial transition,the mediating effects predominantly manifest as null or negative,primarily constrained by inadequate advancements in production technology,upgrading of production models,and improvements in infrastructure.The underdeveloped industrial structure emerges as a critical bottleneck hindering farmland spatial transition.In conclusion,the future efforts should concentrate on the synergistic enhancement of population quality,acceleration of agricultural economic development,and deepening of industrial structural upgrades.These measures are crucial for effectively propelling farmland spatial transition within the Yangtze River Economic Belt,thereby underpinning the advancement towards agricultural modernization.
