水利部日前发布《中国节约用水报告2025》，公布2025年全国用水总量为5944.5亿立方米[1]。其中，农业用水3683.8亿立方米，占比62.0%；工业用水953.7亿立方米，占比16.0%；生活用水936.6亿立方米，占比15.8%；人工生态环境补水370.4亿立方米，占比6.2%[1]。非常规水利用量达256.6亿立方米，约占用水总量的4.3%，其中再生水使用量为213.4亿立方米[1]。
用水效率指标显著改善。万元国内生产总值用水量为42.4立方米，较2024年下降4.5%；万元工业增加值用水量为22.9立方米，较2024年下降7.2%[1]。农田灌溉水有效利用系数提升至0.583，相比2024年提高0.003[1]。规模以上工业企业重复用水率达94.7%[1]。人均综合用水量为423立方米，人均生活用水量为182升/天[1]。
节水管理和产业发展取得显著进展。全国新增实施合同节水管理项目914项，预期年节水量约2.7亿立方米[1]。节水产业产值规模超过8000亿元，全国"节水贷"余额达3635亿元[1]。
The Ministry of Water Resources released the China Water Conservation Report 2025, revealing that total national water consumption reached 594.45 billion cubic meters in 2025.[1] Agricultural water accounted for the largest share at 62.0% of total consumption, followed by industrial water at 16.0%, domestic water at 15.8%, and ecological and environmental supplementary water at 6.2%.[1]
Water efficiency continued to improve across the country, with water consumption per unit of GDP declining by 4.5% compared to 2024, while water consumption per unit of industrial added value decreased by 7.2%.[1] The agricultural sector demonstrated enhanced irrigation efficiency, with the effective irrigation water utilization coefficient reaching 0.583, up 0.003 from the previous year.[1] Large-scale industrial enterprises achieved a water recirculation rate of 94.7%.[1]
Non-conventional water utilization totaled 25.66 billion cubic meters, representing 4.3% of total consumption, with recycled water comprising 21.34 billion cubic meters of this amount.[1] To further promote water conservation, China implemented 914 new contract water management projects nationwide, projected to conserve approximately 270 million cubic meters of water annually.[1] The water conservation industry has grown to exceed 800 billion yuan in output value, while outstanding water conservation loans nationwide reached 363.5 billion yuan.[1]
