The " Red Line of Farmland Area" cannot completely solve the grain security problems in China. We still need to seek new breakthroughs in the quality and yield of farmland. The construction of high standard capital farmland is the important premise to guarantee national grain security. On this basis,this paper has summarized the difficulties we are facing in the construction of high standard capital farmland,and has proposed the methods and measures to construct high standard capital farmland and lay a solid foundation for grain security in China.展开更多

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.展开更多

文摘In the context that global grain security is still in very severe situation,the grain security situation in China is not optimistic as well. The " Red Line of Farmland Area" cannot completely solve the grain security problems in China. We still need to seek new breakthroughs in the quality and yield of farmland. The construction of high standard capital farmland is the important premise to guarantee national grain security. On this basis,this paper has summarized the difficulties we are facing in the construction of high standard capital farmland,and has proposed the methods and measures to construct high standard capital farmland and lay a solid foundation for grain security in China.
文摘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.
