Abstract:: On the base of GIS support, with the calculation method of Renault, etc, the spatial difference of agricultural virtual water in water source area of southern Shaanxi Province in 2010 was analyzed. The results have shown that the gross volumes of virtual water among the three cities are quite different(5.2×10⁹ m³ in Hanzhong, 3.7×10⁹ m³ in Ankang, and 2.3×10⁹ m³ in Shangluo); both Hanzhong and Ankang have similar virtual water structure, such as pork(19%, 22%), oil (21%, 22%), and rice (25%, 14%), while Shangluo is very unlike the former, e.g., pork(21%,), wheat(17%), maize(20%). On county scale, the gross volume of virtual water, and all kinds of agricultural virtual water have shown the characteristics of higher volume along the valley area from which descend to mountainous area, and higher volume in the Daba mountain than that in the Qinling Mountain. The differences were mainly due to traditional customs, geographical conditions, agricultural structure adjustment. This paper put forward an agricultural space optimization scheme from the point of providing more water.
