基于虚拟水的济南市水资源可持续利用研究

水资源问题已成为世界普遍关注的问题,其根本原因就在于它不仅影响、制约现代社会的可持续发展,而且成为本世纪全球资源环境的首要问题,直接威胁人类的生存和发展,水资源可持续利用是当前世界上研究的热门课题之一。济南市是北方严重缺水城市之一,近几年来,随着社会经济的发展,严重影响着城市的发展和人民生活质量的提高。文章将国际上前沿的水资源足迹的计算方法引入到济南市的水资源系统中,利用CROPWAT软件定量测度了济南市主要农贸产品的虚拟水含量。通过济南市水足迹的计算及分析,得出济南市为虚拟水净出口地区,直接危及济南市的水资源安全,建议在济南市水资源有限的情况下,必须在节约用水,提高水资源利用的基础上创新水资源管理思路,实施虚拟水战略,充分利用虚拟水贸易解决水资源短缺问题。

Water Resource Sustainable Utilization Based on Virtual Water of Jinan City

Water resources has become common concern,the fundamental reason is that it does not only affect and restricts the sustainable development of modern society,but also becomes the most important issue of the world’s resources and environment in this century,which is a direct threat to human survival and development.Water resources sustainable utilization is a hot topic in the world currently.Jinan City is a serious water shortage in northern China.In recent years,with the society and economy development,it seriously affects the city’s development and people’s life quality.In this article the forefront of the international water footprint calculation method are introduced to water systems in Jinan City,virtual water content of the main trade products were quantitative measured with CROPWAT software.By the calculation and analysis of Jinan water footprint,the Jinan City is a net exporter of virtual water,which directly endanger the safety of water resources.in the case of limited water resources in Jinan City,in the precondition that water resource must be saved,and the use must be improved,innovative water management ideas should be taken,and implement the virtual water strategy.Water shortage problems will be solved completely by virtual water trade.
