Logical Approach,Historical Transition and Path Exploration of Competition between Urban Spatial Expansion and Agricultural Land Utilization in Beijing
Urban growth limits are reflected in the inevitable constraints imposed by resources and the environment on the urban scale during unrestricted expansion driven by strong demand,one manifestation of which is the conflict between urban expansion and agricultural land utilization.Regarding the understanding of this issue,both theoretical and practical"dual"dilemmas coexist,manifested as divergences over whether"urban expansion and agricultural land use are completely opposed"and controversies over whether"there is a limit to the size of megacities"and"whether farmland should be preserved".In response to the challenges of complex implementation of urban construction space,structural mismatch,mismatch of farmland protection function and disconnection between construction and protection management in Beijing,this article proposes that innovative and regional farmland conversion regulation strategies should be studied based on correct judgment and comprehensive analysis of urban construction needs and the overall situation of farmland resources,to guide urban governments to proactively address the crisis of farmland loss in dealing with the dilemma of"two difficulties"and"multiple difficulties".
