摘　　要：虚拟水是当今水科学的研究热点,被认为是解决粮食与水资源安全的重要策略。在测算中国各地区农畜产品虚拟水总量的基础上,利用伪基尼系数对虚拟水区域差异的成因进行因子分解,表明畜产品中的禽蛋、猪肉、牛肉和农产品中稻谷、小麦、玉米成为影响中国虚拟水空间差异的主要因子。同时,借助锡尔指数对1996—2006年的中国八大区域虚拟水—耕地资源空间差异进行分解,结果表明:虚拟水—耕地资源区域总体差异在不断缩小,影响区域总体差异形成的主导因素是八大区域间的差异。文章旨在揭示地均农畜产品虚拟水区域差异来源以及差异背后体现的农业集约化空间分异特征规律,为制定不同区域类型的农业发展决策提供相应的理论参考。Virtual water has become the enter issue of water sciences, and has been regarded as a main countermeasures to solve risks of food security and water security. On the base of calculating the total quantity of main crop-livestock product virtual water from 1996 to 2006, this paper utilized the causal analysis of Pseudo-Gini Coefficient to decompose the regional virtual water disparities in China. The result evidenced that the livestock such as eggs, pork, beef and the crops such as the paddy, wheat, maize are the primary factors to impact the spatial disparities of the virtual water in China. Meanwhile, based on the decomposition of Theil index sequence using wavelets by different spatial scales, the conclusion showed that the whole regional inequality tend to decrease from 1996 to 2006. By the decomposition of Theil index, it shows that the dominant sources of overall regional inequality is the between-region disparities of the eight regions in China. This paper aims at offering a new method for research of the virtual water per cultivated land size and assisting the formulation of agricultural policies at national and regional levels.
