【摘要】：為探討城市圈產(chǎn)業(yè)用水的驅(qū)動因素,以武漢城市圈為例,利用LMDI法將產(chǎn)業(yè)用水影響因素分為產(chǎn)業(yè)用水單耗、產(chǎn)業(yè)結(jié)構(gòu)、經(jīng)濟(jì)規(guī)模和人口規(guī)模,分析不同因素對產(chǎn)業(yè)用水變化的效應(yīng)。結(jié)果表明:從總體來看,經(jīng)濟(jì)增長和人口擴(kuò)大促進(jìn)產(chǎn)業(yè)用水增長,其中經(jīng)濟(jì)規(guī)模為主導(dǎo)促進(jìn)因素;而產(chǎn)業(yè)用水單耗下降和產(chǎn)業(yè)結(jié)構(gòu)調(diào)整對產(chǎn)業(yè)用水的增長起抑制效應(yīng)。在區(qū)域分析中,武漢市、黃石市、孝感市和潛江市產(chǎn)業(yè)用水的因素效應(yīng)與城市圈全域基本一致;鄂州市僅產(chǎn)業(yè)用水單耗下降對產(chǎn)業(yè)用水變化表現(xiàn)為抑制效應(yīng);黃岡市、潛江市、仙桃市和天門市僅經(jīng)濟(jì)增長對產(chǎn)業(yè)用水變化有促進(jìn)作用。研究結(jié)果可為武漢城市圈產(chǎn)業(yè)用水規(guī)劃與節(jié)水政策提供參考。
[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.
