能源安全、粮食安全、水安全已成为人类生存和可持续发展的三大突出问题。这三者相互关联，直接相互影响;也就是说，能源、粮食和水之间存在着联系。科学认识和正确应对这一问题，对于实现自然资源的可持续发展具有重要意义。本文采用定量分析的方法，估算了2001 - 2016年华中地区能源-粮食生产水足迹和虚拟贸易水流量。提出了与虚拟水流出量相关联的修正水压力指数（MWSI），并结合贸易对当地水资源系统的影响，评价了虚拟水流出对当地水资源系统的压力，沿着。结果表明，能源和粮食生产WF和虚拟贸易水流量呈上升趋势，造成当地和出口地区的水资源紧张。从调整产业结构、优化生产技术、合理划分生态区划等方面提出了保障该地区未来水资源可持续发展的综合政策建议。
Energy security, food security, and water security have become the three most prominent problems in human survival and sustainable development. The three are interrelated and directly affect each other; that is, there exists a nexus between, energy, food, and water (EFW). A scientific understanding and correct response to this is important for achieving the sustainable development of natural resources. This study uses quantitative analysis to estimate the Central China region's energy-food production water footprint (WF) and virtual trade water flow from 2001 to 2016. It proposes a Modified Water Stress Index (MWSI) associated with virtual water outflows and evaluates the pressure exerted by virtual water flowing out, along with the effect of trade on local water re-sources systems. The results indicate that the energy and food production WF and virtual trade water flow are on the rise, causing water stress in local and export areas. Based on the adjustment of industrial structure, optimization of production technology, and rational regionalization of ecological divisions, the paper makes comprehensive policy recommendations to ensure the region's sustainable development of water resources for the future.Y
