Abstract:

Based on the calculation of the total quantity of virtual land of main crops ,the authors computed the Gini coefficient of crops virtual land versus six resourcesenvironmenteconomy factors,i.e.,population,cultivated land,water resources,consumption of chemical fertilizer,management of soilwater erosion and GDP.In addition,the temporal distribution of differences in crops virtual land versus the six factors during the period 1999 to 2009 in China was examined in detail.Results indicated that:the Gini coefficients of crops virtual land versus resourcesenvironmenteconomy factors showing a low matching degree,in relativity,The Gini coefficients of crops virtual land versus population and land resource were high,showing a lower matching degree for crops virtual land versus soilwater erosion,and the Gini coefficients of crops virtual land versus water resources,consumption of chemical fertilizer was the lowest .Regarding spatial distribution characteristics,the authors divided China into eight studied regions,and calculated the imbalance index of crops virtual water versus the six resourcesenvironmenteconomy factors for the partitioned regions.The spatial matching characteristics of crops virtual land versus the six resourcesenvironmenteconomy factors in year 2009 were analyzed,indicating that the main regions affected the outer parts.The outside fairness of the virtual land system for Chinese agricultural products is found to be relatively low,the HuangHuai region is the unfairness of the largest outside Asia，the South of China and Northwest and Northeast is following
