Comprehensive Grain Potential Regionalization Study Based on the Farmland Grading Results

To find out the spatial pattern of comprehensive grain potential, we chose α, Ri, Yi 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 the 12 counties into 4 regions :ⅠHigh 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.
