水资源是一种不可再生的资源。对水资源问题的关注不仅是我们一个区域、一个国家、一个省份,而是全世界共同关注的问题。因此城市节水早已成为我国的基本国策之一。由于城市化的发展.密集了人口和工业,使之本来水资源分配就已失衡的城市用水,显得更加严峻,所以我们对城市的节水问题更应着重考虑、分析,采用因地制宜的节水技术,来解决这个问题。 Water is a non-renewable resource. The concern over the issue of water resources is not only one of our region, one country, one province, but a common concern of the world. Therefore, urban water conservation has long been one of China’s basic national policies. Due to the development of urbanization, urban water consumption that has been imbalanced with population and industry has become even more severe, so we should give more consideration to and analyze the water-saving problems in cities and adopt the water-saving technologies that are adapted to local conditions , To solve this problem.
