摘要

To find out the spatial pattern of comprehensive grain potential,we chose α,R i,Y i from the research output of farmland grading and took them as the basic data; using the Aggregated Advantage Indices and hierarchical cluster analysis methods,finally regionalized all the12 counties into 4 regions: I High potential-regions easy to be mined in the short term,II High potential-regions that can be mined in the long term,III Low potential-regions easy to be mined in the short term,IV Low potential-regions difficult to be mined in the long term. From the study results,we also find out that the Scale Advantage Indices of farmland( SAI) has a strong positive effect on the Aggregated Advantage Indices of grain potential( AAI),so we conclude that it is necessary to maintain and increase a certain amount of farmland area to ensure the regional grain production capacity.
