| 摘要: |
| 面对我国农业水资源持续紧缺和粮食安全主要矛盾向供需结构性矛盾转变的双重挑战，亟须加强实体水-虚拟水统筹管理。本文在分析我国粮食生产及水资源利用现状及存在问题的基础上，明确了以进一步发展实体水-虚拟水耦合流动理论与方法为核心任务的过程水文学是实体水-虚拟水统筹管理的学科基础。梳理了作者及其团队2015—2019年粮食生产与消费系统的过程水文学研究进展。为构建切实可行的实体水-虚拟水统筹管理理论与方法体系，初步提出3个主要发力点：①突破实体水-虚拟水统筹管理技术和方法壁垒，凝练和解决粮食系统的过程水文学关键科学问题；②着眼于全产业链广义水资源高效利用，深化体制机制改革，实现虚拟水管理落地；③加强专业人才培养与支撑。 |

| Abstract: |
| The double whammy in Chinese agricultural production is the sustained water resources shortage and the change in concern over food production that has shifted from food security to the ways the food is produced. Improving integrative management of physical water and virtual waters is urgently needed to resolve these issues. This paper analyzed current situation and the outstanding problems in grain production and water resources utilization in China, and proposed that the key to achieve integrative management of physical and virtual waters is to develop process-hydrology based on the theory of coupled flow of the physical and virtual waters. This paper reviews the research results of our group over the past five years in process-hydrology in grain production and consumption systems in China. It highlights three areas required to construct applicable theory and methods for integrative management of physical and virtual water resources: ① breaking the technical and methodological barriers excising in integrative management of physical and virtual water, and refining and resolving key scientific issues in process-hydrology in grain production system; ② addressing efficient utilization of water resources in the whole industrial chains, improving reform of the system and its underlying mechanisms, and implementing virtual water management; ③ strengthening training and support of specialists in physical and virtual water management. |
