Abstract:

Virtual water spatial distribution law of foodstuff production,foodstuff consumption and their equilibrium in 2007 were 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2×107m3 foodstuff virtual water more than the south.Per capita virtual water of the north was 530 m3,which was much larger than the national average of 460 m3,and the Per capita virtual water of the south was 410 m3.This showed the typical phenomenon of foodstuff virtual water NorthSouth Water Diversion currently in China.②The foodstuff virtual water consumption emerged the opposite law.The southern area had consumed 4 8553×108 m3 foodstuff virtual water more than the north in 2007.The differences of foodstuff consumption between the south and the north had intensified the phenomenon of foodstuff virtual water NorthSouth Water Diversion in China.③From the virtual water equilibrium spatial distribution of view,there were two typical regions of virtual water export: one was the northern border zone which was mainly composed by Heilongjiang,Jilin,Neimenggu,Xinjiang and Ningxia;the other was the annular region of centraleastern China,which mainly included Jiangxi,Hunan,Chongqing,Hubei,Henan,Anhui,Jiangsu,Shandong and Shanxi.There were also two regions of virtual water input:one was the around Bohai Sea region which was composed by Beijing,Tianjin,Liaoning and Hebei;the other was a ring zone which include 13 provinces in northwest,southwest and South China.④Some suggestions for exploitation and application of water resource management about the virtual water equilibrium of foodstuff production and consumption were shortly analyzed in the end.
