Abstract
Scientific identification of the priorities and zoning of cultivated land consolidation can help to implement the policy of"two balances"of cultivated land,and achieve the purpose of guaranteeing national food security and optimizing the spatial pattern of territory.In this paper,using the improved MCR model,considering the expansion effect of different levels of cultivated land sources,we established comprehensive resistance surfaces from natural,ecological and socio-economic aspects to simulate the amount of resistance value in the process of cultivated land expansion.Then,according to the amount of resistance value,we divided the cultivated land consolidation time series of study area into four sub-zones,namely priority consolidation area,optimization consolidation area,restriction consolidation area and prohibited consolidation area.The results show that the priority consolidation area covers an area of 638.11 km2,accounting for 35.65%of the total area.The optimization consolidation areacoversanareaof 669.25km2,accountingfor37.39%ofthetotalarea.Therestrictionconsolidationareacoversanareaof 371.95km2,accounting for 20.78%of the total area.The prohibited consolidation area covers an area of 110.62 km2,accounting for 6.18%of the total area.The results can provide a new method and basis for the comprehensive land consolidation and the formulation of cultivated land in-and-out balance programs.关键词
