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。
The basic reason why water resources have become a common concern in the world is that it not only affects and restricts the sustainable development of modern society, but also becomes the primary issue of global resources and environment in this century. It directly threatens the survival and development of mankind. Water resources can be Continuous use is one of the hot topics in the world at present. Jinan is one of the cities with severe water shortages in the north. In recent years, with the development of economy and society, Jinan has seriously affected the development of cities and the improvement of people’s living standards. In this paper, the international forefront of the calculation of water footprint into Jinan City, water resources system, the use of CROPWAT software quantitative measure of the main agricultural products in Jinan City, the virtual water content. Through the calculation and analysis of water footprint in Ji’nan City, it is concluded that Jinan City is a net export area of virtual water and directly endangers the water resources security in Jinan City. It is suggested that in Jinan City, water resources must be limited and water conservation and water resource utilization must be improved Based on the innovative water resources management ideas, the implementation of virtual water strategy, make full use of virtual water trade to solve the problem of water shortage.
