摘　　要：测算中国主要农产品隐含的虚拟土流入和流出以及节约潜力,对于改善中国土地资源环境具有重要的理论和现实意义。在虚拟土贸易研究的基础上,结合虚拟土核算方法、贸易结构系数、虚拟土节约潜力计算方法,实证分析1996~2016年中国主要农产品进出口贸易节土问题。结果表明:中国主要农产品中棉花和油料平均虚拟土含量较高;虚拟土流出量较大的是油料和蔬菜;虚拟土流入量较大的是谷物、棉花、油料;中国主要农产品贸易中隐含的虚拟土一直处于净流入状态,虚拟土出口贸易结构系数大于1,虚拟土进口贸易结构系数总体小于1,有利于国内土地资源的节约;2016年虚拟土节约潜力达到10416.97万公顷,蕴藏节土潜力巨大。It is of great theoretical and practical significance for the improvement of the environment of China＇s land resources to measure the inflow and outflow of virtual soil and their saving potentials of the main agricultural products. On the basis of the research of virtual soil trade, this paper makes an empirical analysis of the problems of the import and export trade of China＇s main agricultural products from 1996 to 2016, by applying the method of virtual soil accounting, the coefficient of trade structure and the calculation method of the potential saving of the virtual soil. The results are as the followings： the average virtual soil content of cotton and oil is higher than others in China; the larger virtual soil outflow are oil and vegetables, the larger inflow of virtual soil are grain, cotton and oil. The virtual soil in the trade of the main agricultural products in China is always in the net flow, and the structural coefficient of virtual soil export trade is more than 1, the import trade structure coefficient of virtual soil is less than 1, which is beneficial to the conservation of domestic land resources. In 2016, the potential of virtual soil saving is 104 million 169 thousand and 700 hectares.
