Taking colleges, the large users of public domestic water, as an example, the research quantifies the impact of water management on students’ water consumption patterns, builds a water conservation potential model for colleges and simulates the water consumption scenarios, water conservation effects and costs of college students under single and mixed strategies, through a nationwide questionnaire survey and analysis. The research results reveal that the average water consumption of college students in China is 122.7 L/d, and northern colleges are more concerned with real-time transparency of water management, with a 16% higher usage rate of IC cards for charging than that in the southern colleges. Under the current management, the average water consumption per student in the north is 36% less than that of students in the south. The research further established a chain of functions: “faucet-level appliance water conservation→influences habits management→water conservation awareness enhancement→ end- use of water quality recycling”, and the simulation of multiple strategies indicates that the water conservation potential of college students is about 17% to 24%. This study provides data support and scientific evidence for college water management and efficient use of water resources in Chinese universities.

以公共生活用水大户高校为例, 通过全国范围的问卷调查分析, 量化用水管理因素对学生用水方式的影响, 构建高校用水节水潜力模型, 并模拟单一和混合策略作用下高校学生用水情景、节水效果和节水成本。研究结果表明, 我国高校学生人均生活用水量为122.7 L/d, 北方高校更注重用水管理的实时性和透明化, 计费IC卡使用率比南方高16%; 在现有管理方式下, 北方学生人均用水量比南方学生少36%。进一步建立“器具源头节水–管理影响习惯–节水意识提升–末端分质回用”的作用链条, 多元策略模拟结果显示高校学生生活节水潜力为17%~24%。研究结果可为我国高校用水管理和水资源高效利用提供数据支撑和科学依据。
