摘要
提出虚拟水战略优势度的概念并对其概念内涵及影响因素进行分析,从4个方面构建包含12个具体指标的综合定量评价指标体系;运用数学方法对中国31个省级行政区虚拟水战略优势度进行定量评价。发现中国虚拟水战略优势度存在显著的地域差异,区域优势度等级存在"两头多,中间少"的结构特点和"东部高、西部低","南部和北部高、中间低"带状空间分布规律。其中北方4省市和东南8省区优势度最大,是全球虚拟水战略背景对其影响最深远的区域,也是中国虚拟水研究及虚拟水战略实践的关键区域。
Advantage Value of Regional Virtual Water Strategy（AVRVWS） of implementing virtual water strategy and the regional economic, social and under virtual water strategy background all over the world. The connotation is defined to estimate the feasibility ecological effects to different regions and impact factors of AVRVWS are analyzed afterwards, then an assessment index system including 12 indices is established, which consists of four aspects ： supply of water resources, demand of non-agricultural water resources, water resources management and development of agriculture. And the grades of AVRVWS of 31 provinces in China are calculated. The assessment resuhs demonstrate that the grades of AVRVWS in China have notable regional discrepancy. Most of the provinces have the medium grades of AVRVWS, the grades in east China are higher than those the west region, and the grades in the south and north are higher than those of the central region. The grades of AVRVWS in Inner Mongolia, Shanxi, Beijing, Tianjin in North China and Hainan, Guangdong, Guangxi, Zhejiang, Fujian, Hunan, Jiangxi, Shanghai in the south eastern China is the highest in China, so they are the key regions of the virtual strategy research and practice in China.
