虚拟耕地是指隐含在农产品贸易中,生产这些农产品过程中所必需占用的土地资源,有意识的在国际农产品贸易中实施虚拟耕地战略,对于平衡国内耕地赤字、保障粮食安全,发挥我国农产品在国际市场上的竞争优势具有重要的理论指导意义。首先介绍了虚拟耕地的定义及其量化方法,接着分析计算了我国谷物、油籽、棉花等几类主要农产品单位重量的虚拟耕地含量,在此基础上,对当前农产品进出口贸易中虚拟耕地的交易现状及未来发展趋势作了分析和预测。结果显示:近10 a来虚拟耕地净进口量出现持续增长,2006年,通过农产品国际贸易净进口虚拟耕地16 602 903.1 hm2,约占当年全国耕地总面积的12.77%。同时,虚拟耕地净进口量在今后若干年仍将保持增长态势。
Virtual cultivated land refers to land resources implicit in the trade of agricultural products and necessary for the production of these agricultural products. Consciously implementing the virtual cultivated land strategy in international agricultural products trade is of great significance for balancing the deficit of domestic cultivated land, ensuring food security, The competitive advantage in the market has important theoretical guidance. Firstly, the definition of virtual cultivated land and its quantification method are introduced. Then the virtual cultivated land per unit weight of several main agricultural products such as grain, oilseed and cotton in China is analyzed and calculated. Based on this, the virtual farmland in the import and export trade of agricultural products Transaction status and future trends made analysis and forecast. The results showed that the net import of virtual cultivated land continued to grow in the past 10 years. In 2006, the net import of virtual farmland was 16,602,903.1 hm2 in international trade in agricultural products, accounting for 12.77% of the total cultivated land area in China. At the same time, net imports of virtual cultivated land will continue to grow in the coming years.
