The consumption of local blue-green physical water (blue-green PW) is linked to imported virtual water (imported VW) within economic production. The quantitative analysis of interactions between blue-green PW and imported VW is important for integrated management of water resources in inland arid areas. This study used the North Tianshan Mountains (NTM) as a case study to demonstrate the construction of a framework to account for local blue-green PW and imported VW in regional economic production using an input-output model. The results showed that the consumption and transfer of blue-green PW in the agricultural sector constitute the most important part of the water cycle in the NTM. Production consumed relatively less imported VW, 51.3% of which was by the secondary and tertiary industries. VW consumed by the primary industry in the NTM was closely correlated with that by the secondary and tertiary industries, whereas low consumption by the primary industry in the NTM and high demand for primary industry products from outside regions resulted in the direct outflow of large amount of blue-green VW. The current structure of trade in VW also contributed to increasing water shortages in the NTM. This study proposed that the enhancement of the cyclic strength of the primary industry in the local economic system is an effective measure to reduce water loss and improve water utilization efficiency. In addition, by considering the results of industrial linkage analysis of economic sectors, this study proposed that the government should promote the development of industries with large water storage potential, such as construction, manufacturing and forestry, and that adjustment of the structure of local industries should be accelerated so as to reduce the loss of VW during local economic production and trade flows of the primary industry.

将内陆干旱地区的局部用水与进口虚拟水联系起来:方法,应用和执行因素

在经济生产中,当地蓝绿色的物理水(蓝绿色的PW)的消耗与进口的虚拟水(进口的大众汽车)相关。蓝绿色PW和进口VW之间相互作用的定量分析对于内陆干旱地区水资源的综合管理非常重要。本研究以北天山山脉(NTM)为例,通过投入产出模型,说明了在区域经济生产中考虑当地蓝绿色PW和进口VW的框架的构建。结果表明,农业部门蓝绿色PW的消耗和转移构成了NTM中水循环的最重要部分。生产消耗的进口大众汽车相对较少,其中51.3%来自第二产业和第三产业。NTM的第一产业消费的大众汽车与第二产业和第三产业的大众汽车紧密相关,而NTM的第一产业的低消费和外部地区对第一产业产品的高需求导致大量的汽车直接流出。蓝绿色的大众。大众的当前贸易结构也加剧了NTM的水资源短缺。这项研究提出,增强第一产业在当地经济体系中的循环强度是减少水损失和提高水利用效率的有效措施。此外,考虑到经济部门的产业联系分析结果,该研究建议政府应促进具有巨大蓄水潜力的产业的发展,例如建筑业,
