第26个全国城市节约用水宣传周活动于5月14日~20日举办,今年的主题是“全面建设节水城市,修复城市水生态”。近年来,我国城市节水工作取得了明显成效,城市用水效率不断提高。但由于水质性、水量性、结构性和工程性等复杂缺水因素,我国近一半的城市都处于“缺水”和“严重缺水”的区间,水资源形势不容乐观。
The 26th National Urban Water Conservation Week was held on May 14-20, the theme of this year is “to build a water-saving city in an all-round way and restore urban water ecology.” In recent years, China’s urban water-saving work has achieved remarkable results, and urban water use efficiency has been continuously raised. However, due to the complicated water shortage factors such as water quality, water quality, structure and engineering, nearly half of China’s cities are in the range of “water shortage ” and “severe water shortage ”, and the water resources situation is not optimistic.
