【摘要】：西北地區(qū)在我國水資源短缺問題中表現(xiàn)最為突出，無論是先天的水資源供給量不足，還是不均衡發(fā)展引起尖銳的水資源供需矛盾，都嚴(yán)重制約了西北地區(qū)社會經(jīng)濟(jì)的可持續(xù)發(fā)展。然而，西北地區(qū)繼續(xù)開發(fā)水資源的潛力已不大，跨區(qū)調(diào)水須在國家統(tǒng)籌計劃下以大規(guī)模工程來考慮，相對而言，污水資源化及產(chǎn)業(yè)用水結(jié)構(gòu)調(diào)整是解決西北地區(qū)水資源不足問題和提高水資源承載力的有效途徑，同時符合未來西部大開發(fā)、區(qū)域社會經(jīng)濟(jì)可持續(xù)發(fā)展的目標(biāo)。 通過追蹤大量的國內(nèi)外有關(guān)污水資源化及產(chǎn)業(yè)用水結(jié)構(gòu)調(diào)整對水資源承載力影響研究的文獻(xiàn)，發(fā)現(xiàn)系統(tǒng)動力學(xué)方法在水資源承載力評價中運(yùn)用成熟；關(guān)于污水資源化對水資源承載力影響的研究缺少定量分析；產(chǎn)業(yè)用水結(jié)構(gòu)調(diào)整對水資源承載力影響的研究側(cè)重水資源約束下產(chǎn)業(yè)結(jié)構(gòu)調(diào)整的選擇；將兩者結(jié)合起來分析對水資源承載力影響的研究更是不多。因此，本文利用污水資源化及產(chǎn)業(yè)用水結(jié)構(gòu)調(diào)整兩個關(guān)鍵因素，通過系統(tǒng)動力學(xué)方法定量分析對西北地區(qū)水資源承載力的影響程度，為西北地區(qū)有效提高水資源承載力提供相應(yīng)對策和建議。 (1)利用系統(tǒng)動力學(xué)原理進(jìn)行污水資源化對水資源承載力影響的三個反饋回路分析，模擬評價污水資源化對西北地區(qū)水資源承載力的影響程度。結(jié)果顯示污水資源化能力不變時，水資源未來可承載人口及經(jīng)濟(jì)規(guī)模的能力是很弱的；當(dāng)污水資源化能力相關(guān)參數(shù)提高10%時，水資源未來可承載的人口及經(jīng)濟(jì)規(guī)�？商岣�20%；同時說明污水資源化能力適度提高對水資源承載力提高作用顯著。 (2)通過西北地區(qū)三大產(chǎn)業(yè)萬元GDP用水量的趨勢分析，得出西北地區(qū)第一、二、三產(chǎn)業(yè)最佳用水比例為0.779:0.195:0.266。結(jié)果顯示采用此用水比例，水資源不僅可以承載目前的經(jīng)濟(jì)規(guī)模，而且可達(dá)到最大節(jié)水量191.361×108m3；但采用其它產(chǎn)業(yè)用水比例不是水資源承載經(jīng)濟(jì)規(guī)模的能力下降，就是節(jié)水效果達(dá)不到最佳。 (3)將污水資源化能力提高10%同時采用三大產(chǎn)業(yè)最佳用水比例0.779:0.195:0.266，通過相關(guān)變量和參數(shù)的選擇、基本約束條件的設(shè)計，運(yùn)用系統(tǒng)動力學(xué)模擬分析兩個因素同時作用對水資源承載力的影響情況。結(jié)果顯示2020年水資源可承載的人口及經(jīng)濟(jì)規(guī)模比現(xiàn)狀水平下提高近30%，，各指標(biāo)值接近規(guī)劃目標(biāo)值，而且工業(yè)增加值的提高幅度最大；同時反映出污水資源化能力提高對水資源承載力的影響程度相對大于產(chǎn)業(yè)用水結(jié)構(gòu)調(diào)整對水資源承載力的影響程度。
[Abstract]:In the northwest area , the problems of water resources shortage in China are the most prominent , whether the supply amount of water resources in the first day is insufficient or the uneven development causes acute water resources supply and demand contradiction , which seriously restricts the sustainable development of the social economy in the northwest area . However , the development of water resources in the northwest area has not been large . However , the adjustment of water resources and industrial water use in the northwest area is an effective way to solve the problem of water resources shortage in the northwest area and to improve the water resources carrying capacity , and meet the goal of sustainable development of the western region in the future and the sustainable development of the regional socio - economic development . It is found that the system dynamics method is mature in the evaluation of water resources carrying capacity by tracing a large number of domestic and foreign literatures about the influence of wastewater reclamation and industrial water structure adjustment on water resources carrying capacity . ( 1 ) Based on the analysis of three feedback loops of the effect of wastewater reclamation on the water resources carrying capacity , the influence degree of wastewater reclamation on the water resources carrying capacity in the Northwest China is simulated . The results show that the capacity of water resources to carry the population and economic scale is very weak when the resource capacity of the wastewater is unchanged ; when the related parameters of the wastewater reclamation capacity are increased by 10 % , the population and economic scale of the water resources in the future can be increased by 20 % ; meanwhile , the improvement of the water resource capacity is obvious . ( 2 ) According to the trend analysis of the water consumption of the three industries in the Northwest China , the optimum water consumption ratio of the first , second and third industries in the Northwest China is 0.779 : 0.195 : 0.266 . The results show that the water resources can not only carry the present economic scale , but also can reach the maximum water saving capacity of 191.361 脳 108m3 , but the water saving effect is not the best . ( 3 ) The capacity of wastewater reclamation is increased by 10 % , and the optimum water consumption ratio of three industries is 0.779 : 0.195 : 0.266 . The influence of two factors on the water resources carrying capacity is analyzed by the selection of relevant variables and parameters . The results show that the population and economic scale of the water resources can be increased by nearly 30 % compared with the current situation level .
