文摘

Serious spatial mismatch exists between grain production and farmland resources in China. Spatial mismatch has been aggravated by grain production barycenter’s shift to the north China. Build a measuring model of potential farmland based on Potential Crop Rotation data. Inefficient use and decreasing amount of available farmland have become the main causes of grain production decline. Policy suggestions provided to cope with the spatial mismatch and defuse China’s food security crisis.
