中国区域粮食生产与消费中的虚拟耕地平衡研究

从不同尺度分析了我国2008年粮食生产、消费中的虚拟耕地含量及虚拟耕地平衡空间分布规律.主要结论为:①2008年粮食生产虚拟耕地北方比南方多32396.8×107m2,人均粮食生产虚拟耕地量北方远远高于全国平均水平和南方,因粮食生产形成较为典型的虚拟耕地“北土南调”现象.②2008年粮食消费虚拟耕地北方比南方多6851.62×107m2.③从粮食生产与消费的虚拟耕地平衡空间分布规律来看,2008年虚拟耕地调出区全部位于我国北方地区,集中分布在两大地带:一是由黑龙江、吉林、内蒙古、新疆、宁夏5省(区)组成的我国北方边境沿线地带,二是由河南、安徽组成的中部区;调入区则集中在由东部沿海地区、中部省份和西部内陆省份组成的环状地带.

Regional Grain Production and Consumption of Farmland Balance of Virtual in China

From 2008 grain production and consumption cultivated content of virtual space distribution and dynamic variation and balance,the main conclusions were as follows: ①2008 grain production in north to south of virtual cultivated land was more than 32396.8 million square meter,per capita grain production area of virtual cultivated land in north was far higher than the national average for food production,and the formation of the typical virtual farmland was "Soil in North Moving from the South".②The 2008 grain consumption cultivated in north was more than south of virtual 6851.62 million square meter.③From food production and consumption of farmland balance of virtual spatial distribution,2008 in virtual farmland in north China region,all concentrated distribution in the two areas: One was by Heilongjiang,Jilin,Inner Mongolia,Xinjiang,Ningxia five provinces(areas) in north China border area,the other was composed by Henan,Anhui Province in central area,the area was transferred by the eastern coastal areas in west and central provinces,consisting of the circular area inland provinces.
