RESEARCH ON THE PRIMARY CROP-LIVESTOCK PRODUCT VIRTUAL WATER REGIONAL DISPARITIES IN CHINA
计算1996-2006年中国主要种养产品虚拟水量，用伪基尼系数和泰尔指数分解区域差异，发现畜禽和稻麦玉米是主要影响因素，区域间差异是总体不平等的主要来源。
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.
