【摘要】：为探讨城市圈产业用水的驱动因素,以武汉城市圈为例,利用LMDI法将产业用水影响因素分为产业用水单耗、产业结构、经济规模和人口规模,分析不同因素对产业用水变化的效应。结果表明:从总体来看,经济增长和人口扩大促进产业用水增长,其中经济规模为主导促进因素;而产业用水单耗下降和产业结构调整对产业用水的增长起抑制效应。在区域分析中,武汉市、黄石市、孝感市和潜江市产业用水的因素效应与城市圈全域基本一致;鄂州市仅产业用水单耗下降对产业用水变化表现为抑制效应;黄冈市、潜江市、仙桃市和天门市仅经济增长对产业用水变化有促进作用。研究结果可为武汉城市圈产业用水规划与节水政策提供参考。
[Abstract]:In order to explore the driving factors of industrial water use in urban area, taking Wuhan city circle as an example, the influencing factors of industrial water use are divided into industrial water consumption unit consumption, industrial structure, economic scale and population scale by using LMDI method. The effects of different factors on industrial water use are analyzed. The results show that, as a whole, economic growth and population expansion promote industrial water use growth, in which the economic scale is the leading factor, while the decline of industrial water consumption and the adjustment of industrial structure inhibit the growth of industrial water use. In the regional analysis, the factor effect of industrial water use in Wuhan, Huangshi, Xiaogan and Qianjiang cities is basically consistent with the whole area of the urban area; in Ezhou City, only the decline of industrial water consumption is an inhibition effect on the change of industrial water use; Huanggang City, Qianjiang City, Xiantao City and Tianmen City only economic growth to promote changes in industrial water use. The results can provide reference for industrial water use planning and water saving policy in Wuhan City Circle.
