| 摘 要： | 将区域产业节水的综合效应分解为产业结构调整、产业用水效率变化及两者的交互作用,产业节水具有层次性和时段尺度性特点。通过对浙江省近10年来的产业节水效应进行分析,在不同的时段尺度上,产业用水效率变化产生的节水效应高于产业结构调整,而交互节水效应的时段性表现更为明显。在三次产业层面上,第三产业节水效应不明显;第一、二产业用水效率的提高及第一产业结构比重的降低成为节水效应的主导方面。在各产业内部节水效应上,第一产业的农业部门和第二产业的工业部门用水效率的提高起主导作用。综合分析表明产业用水效率的提高成为浙江省近10年来节水的最主要驱动力。 |

| Abstract: | Water-saving synthetic effect of regional industry is decomposed as industrial restructuring and industrial water use efficiency change and their interaction.The effect has both hierarchy and time interval characteristics in itself.Through an analysis of recent 10 years’ statistic data concerned in Zhejiang Province,water-saving effect caused by the industrial water use efficiency change exceeds the industrial restructuring while their interaction more obvious in different time scale.As for the water-saving effect of regional industry the third industry is not obvious,while water use efficiency improvement of primary industry and secondary industry with added value proportion decrease in the primary industry become dominant among three industries.Water use quota decreases in agricultural and industrial department become the main effects in their industry interior structure.The research results show that water use efficiency improvement becomes the main driving force to water-saving effect of regional industry in the 10 years in Zhejiang Province. |
