鉴于当前我国虚拟水经济影响研究方面尚较少触及的现实,该研究用虚拟水战略的视角,通过构建定量评价指标体系的办法来探究我国当前农业生产布局的优化问题.首先,用人均农村人口主要农畜产品虚拟水含量指标定量表征我国农业生产空间布局现状,发现我国农业生产空间布局存在明显的"北方多、南方少"特点,其中,高值区由展布在北方地区的黑龙江、吉林、宁夏、新疆等10个省区组成;而主低值区则分布在我国东南和西南沿海一带.然后,为探究虚拟水战略背景下我国农业生产的理想布局模式,提出区域农业生产优势度的概念,分析其影响因素,运用定量评价模型计算各省级区域的农业生产优势度.发现区域农业生产优势...

Spatial distribution status of agricultural production in China was analyzed using the index of per capita virtual water of main agricultural and animal production.It is found that agricultural and animal production in north China＇s is higher than that in south China.The high-value areas are built up by the provinces of surround Bohai Sea,Heilongjiang,Jilin,Ningxia,Xinjiang.The principal low-value area is distributed in the coastal provinces of south-east and south-west China.The minor low-value area is assembled by many provinces of the centr...
