近年来最严格水资源管理制度在促进水资源管理方面的作用越来越显著,万元工业增加值用水量为用水效率控制红线的重要指标,体现了工业用水效率的高低。研究最严格水资源管理制度对万元工业增加值用水量的影响,对推动各地落实最严格水资源管理制度、支撑水资源管理工作具有重要的意义。以浙江省为典型案例,通过MK-P检验法分析2005—2017年万元工业增加值用水量的变化规律,并建立指标评价体系,利用改进层次分析法定量化地描述各指标的重要性,根据案例的实际情况对评价模型进行多目标决策评价。结果表明:最严格水资源管理制度实施后,指标下降明显,建立的评价体系合理,相关工作的影响权重达到了71%,工业用水效率提高,成效影响显著。

In recent years, the most stringent water resource management system has played an increasingly significant role in promoting water resource management. Water consumption per 10,000 yuan of industrial added value, which reflects the efficiency of industrial water use, is an important indicator of the control red line for water use efficiency. Studying the impact of the most stringent water resources management system on the water consumption per 10 000 yuan of industrial added value is of great significance to promoting the implementation of the most stringent water resources management system and supporting water resources management. With Zhejiang Province as a typical case, the change rule of water consumption per 10 000 yuan of industrial added value from 2005 to 2017 is analyzed via the MK-P test method. An indicator evaluation system is established, and the importance of each indicator is depicted quantitatively using improved analytical hierarchy process (AHP). According to the actual situation of the case, the evaluation model was evaluated by multi-objective decision-making. Results show that, after the implementation of the most stringent water resource management system, the index have dropped significantly. The evaluation system is reasonable, and the influence weight of relevant work reached 71%. The most stringent water resource management system has significant influence on improving the industrial water use efficiency.
