当今社会一切经济活动、社会活动都极大地依赖着水资源的供应质量和数量。 随着中国人口增长和城市系统的不断扩大,华北、西北水资源的供需矛盾正日趋尖锐。 水——人类社会发展和一切生命不可缺少的最宝贵资源之一。可是,造物主对中国人似乎并不那么偏爱。 In today’s society, all economic activities and social activities rely heavily on the quality and quantity of water supplied. With the population growth in China and the continuous expansion of urban systems, the contradiction between supply and demand of water resources in North and Northwest China is becoming increasingly acute.
