陕西省2003年水资源足迹测评与分析

水足迹由于考虑了社会经济系统中的虚拟水消费量,较完整刻画了人类对水资源的真实占用和消费情况,为水资源的科学管理提供了一个崭新的视角。利用水足迹模型计算2003年陕西省全省资源水足迹和人均水足迹,结果表明:陕西省2003年的水足迹为248.862亿m3、人均水足迹为671.656 m3,水资源集约利用度为9.638元/m3,2003年陕西水资源压力指数为331.4%。提出了降低水足迹以缓解水资源压力的几条途径,探讨了今后水足迹研究的方向。

Evaluation and analysis on water footprint of Shaanxi Province2003

Water footprint means the total quantity of water resource that maintains the consumption of certain crowd of one country(district) under certain living standard.Because of considering virtual water volume of consumption of social economic system,the footprint portrayed the mankind's true possession and consumption situation of water resource,and offered a brand-new visual angle for scientific management of water resource.The meaning of the virtual water contributes to improving people's warred consciousness to water resource,to the consumption mode that advocates being economized on water and gives the important strategic inspiration in water resource management.Using water footprint model,the total water footprints and per person water footprint of Shaanxi Province in 2003 have been calculated.The result showed that the water footprint of Shaanxi Province in 2003 was 24,886,200,000 m~3.The per person water footprint was 671.656 m~3.Several ways for reducing the water footprint have proposed in order to alleviate the water resource pressure.The future study direction of water footprint has been discussed.
