襄垣县虚拟水消费及虚拟水战略研究

水资源短缺已成为制约社会经济发展的重要因素。分析了1978-2007年山西省襄垣县虚拟水消费量,结果表明,在城市化进程中,该县虚拟水消费量呈上升趋势,城镇增幅远大于农村;消费结构趋于多样化;各乡镇人均虚拟水消费量有较大差异,经济较发达地区的人均虚拟水消费量较低。发现采取积极的消费模式可以在不影响居民生活水平的前提下极大地节约用水,从而缓解水资源压力。最后结合襄垣县的实际情况,简要分析了在襄垣县实施虚拟水战略的基本思路。

Analysis on the spatial and temporal variety of virtual water consumption in Xiangyuan County

Virtual Water research is a hot issue in today＇s water research.In this paper,the spatial and temporal variation of virtual water consumption was analyzed from 1978 to 2007 in Xiangyuan County Shanxi Province.The results showed that the county had a upward trend in virtual water consumption,urban growth was much greater than rural areas in the process of urbanization;Virtual water consumption of food products had reduced,virtual water consumption of livestock and aquatic products had increased,and the consumption structure became diversification;There were greater differences in different townships,and economically more developed regions had lower per capita consumption of virtual water.In a word,without affecting the living standards of the residents,adopt a positive consumption patterns could greatly conserve water,and thus ease the pressure of water resources.
