摘要
摘要:食物-能源-水（food-energy-water, FEW）是人类赖以生存的基础资源，且三者之间存在密切的关联关系．2011年世界经济论坛首次将“FEW风险群”列为未来10年影响全球格局的3类重要风险集合．本文基于物质流和能量流的分析方法，识别出3种代谢网络中具有关联的节点和路径．基于识别出的关联节点和路径，分析了FEW间的关联及相关指标．结果表明：2017年广州市食物生产相关的用水总量为12.19×10⁸ m³，能源相关的用水量为22.91×10⁸ m³，食物生产有关的能源消耗为11.36×10⁴ tce，与水有关的能源消耗为21.27×10⁴ tce；广州市资源消耗水平逐渐增加，资源指数迅速恶化，资源自给率水平逐渐降低，对环境影响也呈加强趋势，各子系统间的依存度和关联逐渐加强．

Abstract:The food-energy-water (FEW) nexus is fundamental for human survival．The 2011 World Economic Forum (WEF) listed “FEW risk clusters” for the first time as a set of three important risks that will affect global landscape in the next decade．Here an analytical method based on material and energy flows was used to identify nodes and paths in the three metabolic networks．Association between FEWs and related indicators were analyzed according to identified nodes and pathways．Total water consumption related to food production in Guangzhou in 2017 was found to be 12.19×10⁸ m3, energy-related water consumption was 22.91×10⁸ m3, energy consumption related to food production was 11.36×10⁴ tce, and energy consumption related to water was 21.27×10⁴ tce．It was found that resource consumption in Guangzhou gradually increased, resource index rapidly deteriorated, the level of resource self-sufficiency gradually decreased, impact on the environment showed a strengthening trend, the dependence and nexus between subsystems gradually strengthened．
