用水效率去年全国第一，特大城市北京如何做好节水文章？

Core Viewpoint - Beijing, facing severe water scarcity with a per capita water resource of only 150 cubic meters, has achieved the highest water efficiency in the country, with water consumption of 8.45 cubic meters per 10,000 GDP in 2024, showcasing effective water conservation strategies [1][8]. Group 1: Water Efficiency Achievements - In 2024, the water consumption per 10,000 GDP in Beijing is projected to be 8.45 cubic meters, leading the nation [1]. - The China World Trade Center (CWTC) has reduced its water consumption to 2.95 cubic meters per 10,000 GDP, significantly lower than the average of 5.06 in Chaoyang District [4]. - From 2012 to 2024, the water consumption per unit area in CWTC decreased from 1.63 tons/㎡ to 1.18 tons/㎡, a reduction of 27% [4]. Group 2: Water Management Initiatives - Chaoyang District has established a four-level management system for water conservation, ensuring dynamic data sharing among water departments, supply companies, and users [5]. - The district's GDP is expected to exceed 900 billion yuan in 2024, with a water consumption of 4.17 cubic meters per 10,000 GDP, indicating efficient water use [4]. Group 3: Legislative and Institutional Framework - Beijing has implemented comprehensive water-saving legislation, including the "Beijing Water Saving Regulations" and the "14th Five-Year Plan for Water Saving," which incorporates water consumption control into government performance assessments [8]. - Between 2014 and 2024, the water consumption per 10,000 GDP in Beijing decreased by 33.7%, while the industrial value-added water consumption dropped by 61.3% [8]. Group 4: Technological Innovations - Beijing University of Technology has developed water-saving devices and implemented rainwater collection and recycling systems, significantly reducing water consumption on campus [9][10]. - The university has invested over 4 million yuan in water-saving projects during the 14th Five-Year Plan, achieving a total water savings of 7.2 million tons since 2006 [10].
