摘要:

水资源、能源、粮食安全是实现可持续发展的重要支撑,与可持续发展各目标存在紧密联系。论文基于水—能源—粮食纽带关系(WEF nexus)系统相关的理论、方法与应用等最新研究成果,根据研究对象的时空尺度,考虑系统物质、能量、信息交换,重新解析了WEF nexus系统的定义与组成、内部相互作用过程、输入与输出、影响因素;阐明了气候变化对水、能源、粮食3个子系统及其纽带关系,以及不同类别人类活动对WEF nexus系统的正面和负面影响。进一步分析了水、能源、粮食与可持续发展目标的关联性,以“研究主题—学科理论—技术方法—实践应用”为主线,提出了面向可持续发展的WEF nexus系统研究框架及其3个核心研究内容:WEF nexus系统内部纽带关系和总体状态评估、系统变化的驱动因素识别和系统的外部性影响分析。最后,针对WEF nexus系统跨学科分析的需求,基于纽带关系的理论研究与应用不足的现状、系统时空边界的多样性特点,剖析了多学科交叉与融合研究的具体思路;提出了基于纽带关系的综合性分析指标与计算方法的研究设想;指出了多尺度研究成果耦合应用的必要性和方式。研究可为WEF nexus系统的基础理论与应用实践提供新的视角,为全球与区域可持续发展目标的分析提供思路和方法借鉴。

Abstract:

The securities of water, energy, and food are three sustainable development goals (SDGs) and have close interactions with other SDGs. Based on the recent studies of the theory, methodology, and application of the water-energy-food nexus (WEF nexus) system, this study analyzed the WEF nexus system in terms of its definition and composition, internal interaction processes, inputs and outputs, and influencing factors. In the process of analysis, the characteristics of the spatial and temporal scales of the research object were taken into account, and the inputs and outputs of the WEF nexus system were clarified from the perspective of the material, energy, and information flows. This study also illustrates the positive and negative impacts of climate change on the water, energy, and food subsystems and their interactions, as well as the impacts of human activities on the WEF nexus system. Furthermore, a research framework of the WEF nexus system covering research themes-disciplinary theories-technical methods-practical applications was proposed, according to the interactions of the WEF nexus system and other SDGs. The introduced framework illustrates three research topics: 1) Linkages within the WEF nexus system and the overall state. 2) The drivers of system change. 3) The influences of the system on socioeconomic development, ecological and environmental protection, and so on. At last, this study highlights the urgent need for interdisciplinary analysis of WEF nexus systems due to the insufficient research and application of nexus relationships and the diversity of spatial and temporal boundaries. The research perspectives based on comprehensive analysis indicators and calculation methods of nexus relationships are presented, and the necessity and ways of coupled application of multi-scale research results is introduced. This study provides a new insight into the research on the basic theory and application of the WEF nexus system, as well as some guidance on the analytical ideas and methods of global and regional sustainable development goals.
