从省级和8个二级区域尺度上分析我国2007年粮食生产和消费中的虚拟水含量的空间分布规律以及粮食生产和消费中的虚拟水平衡规律,得出如下结论:首先,粮食生产虚拟水量北方比南方地区多31 975.2×10~7 m~3,人均粮食生产虚拟水量北方地区为530m~3/人,远高于全国平均水平的460m~3/人,而南方地区则只有410m~3/人. 说明我国当前粮食生产存在较为典型的虚拟水资源"北水南调"现象;其次,全国粮食虚拟水消费量南方比北方地区多4 855.3亿m~3,恰好与粮食生产的虚拟水空间分布规律相反. 南北方粮食消费水平的差异加剧了我国粮食生产虚拟水资源"北水南调"现象的发生;再次,从粮食生产和消费的虚拟水平衡空间分布...

Virtual water spatial distribution law of foodstuff production,foodstuff consumption and their equilibrium in 2007were analyzed after calculated the virtual water contained in foodstuff production and consumption in each province and sub-region in China.Conclusions were as follows：①The northern area had produced 31 975.2×107 m^3 foodstuff virtual water more than the south.Per capita virtual water of the north was 530m^3,which was much larger than the national average of 460m^3,and the Per capita virtual water of the south was 410m^3.This sho...
