我国是一个水资源不足的国家, 人均水资源占有量不足世界平均值的四分之一。北京缺水更为严重,人均水资源占有量不足300立方米,是世界均值的三十分之一,不及世界上以水资源匮乏著称的以色列。目前北京市的地表水开发程度已经很高,地下水由于不合理开采,造成全市地下水量的严重亏损,随着工农业生产的发展和人民生活水平的提高,各业用水量不断增长,北京市水资源的供需矛盾更加尖锐。
Our country is a water-scarce country with a per-capita share of less than a quarter of the world average. Beijing is suffering from more water shortages, with less than 300 cubic meters of water per capita, making it one-thirtieth of the world’s averages less than the world-renowned Israel, which is poorly water-scarce. At present, the development level of surface water in Beijing is already very high. Due to the unreasonable exploitation of groundwater, the groundwater loss in the city is seriously devastated. With the development of industry and agriculture and the improvement of people’s living standard, the water consumption of various industries is increasing. The contradiction between supply and demand is more acute.
