随着世界经济发展和人口数量的增加,水资源危机已超出其它能源成为全球首要的资源危机,受到各国的广泛重视。我国目前人均水资源占有量只有2238.6立方米,仅为世界人均占有量的1/4,居世界第121位,分布不均,开发利用难度大。哈尔滨市是全国300个缺水城市之一,长期供水短缺问题,已成为急待解决的战略性问题。
With the development of the world economy and population increase, the crisis of water resources has surpassed other sources of energy and has become the most important resource crisis in the world, attracting the widespread attention of all countries. At present, the per capita water resources in our country occupy only 2238.6 cubic meters, only 1/4 of the world average, ranking the 121st in the world, with uneven distribution and difficult exploitation and utilization. Harbin, one of the 300 water-scarce cities in the country, has a long-term shortage of water supply and has become a strategic issue that needs to be resolved urgently.
