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。文章引用虚拟水理论,计算了2011年西安的水足迹状况,并对西安市的水资源相关指标进行分析。结果表明西安市2011年的水足迹为57.66×108m3,人均水足迹为677.28m3·a,水资源自给率为0.504,水资源压力指数为174.3%,说明西安市水资源严重短缺,高虚拟水进口依赖度会给西安的经济发展带来巨大的压力。
The fundamental reason why water resources issue has become a universal concern is that it not only affects and restricts the sustainable development of modern society, but also becomes the primary issue of the global resource and environment in this century and directly threatens the survival and development of mankind. The article quotes the theory of virtual water, calculates the water footprint in Xi’an in 2011, and analyzes the water resources related indicators in Xi’an. The results showed that the water footprint of Xi’an in 2011 was 57.66 × 108m3, the water footprint per capita was 677.28m3 · a, the self-sufficiency rate of water resources was 0.504, and the pressure index of water resources was 174.3%, indicating a serious shortage of water resources in Xi’an and a high virtual water import Dependence on the economic development in Xi’an will bring tremendous pressure.
