摘要:
分析了我国近年来产业发展和产业结构的变迁过程，随着我国城市化的进一步发展，当前第三产业在国民经济中的贡献已跃居第一，其用水量也占到了城市总用水量的60%左右。通过对比分析我国与美、英、日等发达国家在万元GDP用水量，第二、三产业万元GDP增加值用水量以及用水效益等指标的差异，发现我国第三产业节水存在巨大空间，若不积极开展节水，到2035年第三产业用水量将增加至现状的2.7 倍，将是城市现状用水总量的1.6 倍，第三产业节水俨然已成为我国城市节水的主攻方向。通过分析我国第三产业节水发展不平衡、不充分等问题，提出了由文化、管理、科技三轮驱动的节水理念和节水模式；针对第三产业用水大户空调冷却循环水系统的节水问题，深入开展研究分析，并提出了相应的节水措施；对实现节水优先的治水方针、提升以水资源为刚性约束条件的城市承载力有着积极的意义，为进一步促进新时代我国城市节水向纵深和精细化发展提供了新思路。
Abstract:
This article analyzes the process of China’s industrial development and industrial structure changes in recent years. With the further development of China’s urbanization, the current tertiary industry’s contribution to the national economy has occupied the first place, and its water consumption has also accounted for about 60% of the total urban water consumption. Through a comparative analysis between China and developed countries such as the United States, Britain, and Japan, it shows the differences in water consumption per 10 000 yuan of GDP, water consumption per 10 000 yuan of value-added GDP in the secondary and tertiary industries, and water efficiency. It is found that there could be further progress for water saving in China’s tertiary industry. If we failed on water saving, the water consumption of the tertiary industry will increase to 2.7 times of the current valve by 2035, which will be 1.6 times of the current urban total water consumption. Therefore, water saving in the tertiary industry has become the main direction of water saving in Chinese cities. Through the analysis of the unbalanced and inadequate development of water saving in the tertiary industry in China, the water-saving concept and water-saving model driven by culture, management, and technology are proposed. Besides, this article has also conducted a deep investigation on the water saving of the air-conditioning cooling circulating water system, which is the major water users in the tertiary industry. Related water saving measures are suggested. This paper contributes to the development on the water-saving and support is as a priority governance policy, which could improve the urban carrying capacity limited by water resources rigid constraints, and also provide new ideas for further promoting the in?depth and refined development of urban water saving in China in the new era.
