| 总结目前对于水足迹测评的常用方法, 并简要介绍了虚拟水的核算原则。通过对2000年中国各省人均水足迹与人均用水量的比较, 借助于统计分析软件SPSS对各省区人均水足迹进行了系统聚类, 在GIS软件的支持下, 将中国31个省区的人均水足迹划分为5类, 其中人均水足迹在480 m3/a以下的仅有广西, 480550 m3/a的有四川、贵州、江西、浙江, 700850 m3/a的有新疆、甘肃、宁夏、山西、北京、上海、天津、黑龙江、辽宁, 850950 m3/a的有内蒙古和青海, 其余省份介于550700 m3/a, 制作了中国2000年各省人均水足迹空间分布图。 |

| The article summarized the common methods of measuring water footprint currently, and analyzed synoptically the usual principle of calculating virtual water.The relationship of consumption of water footprint per capita and water use in provinces of China in 2000 is analyzed.With the help of statistical analytical software SPSS, a cluser analysis is made of consumption of water footprint per capita in provinces of China.In the end, based on GIS (Geographical Information System) , a spatial distribution map is made and the consumption of water footprint per capita in 31 provinces of China are divided into five types.The result is that: only Guangxi's consumption of water footprint per capita is below 480 m3/a;Sichuang, Guizhou, Jiangxi and Zhejiang are between 480～550 m3/a;The consumption of water footprint per capita in the provinces of Xinjiang, Gansu, Ningxia, Shanxi, Beijing, Shanghai, Tianjin, Heilongjiang, Liaoning is categorized between 700～850 m3/a;The provinces of Inner Mongolia and Qinghai have a high consumption of 850～950 m3/a;Other provinces lie in 550～700 m3/a. |
