| Abstract: |
| 【Objective】In the changing environment, the contradiction between supply and demand of water resources is intensified. Agriculture is the main water consumption sector in China. The optimal allocation of agricultural water resources is an effective way to alleviate water shortage and improve the utilization efficiency of water resources. 【Methods】Based on the concept of agricultural water resource, the advance of crop irrigation system optimization, crops planting structure optimization, cropping spatial distribution optimization, the irrigation water more joint control, optimal allocation of regional agricultural water resources, water, food and collaborative optimization research on optimal allocation method of the system were reviewed. 【Conclusion】It is pointed out the research problems and challenges in agricultural water resources allocation, and proposed further focus on research in terms of planting structure optimization adaptation to climate change, considering the virtual water trade and the water and carbon footprint, multi-source irrigation water optimization based on the transformation of binary water cycle simulation, synergistic optimization of the water- food - energy-ecology nexus, and methods for determination of the suitable ecological structure and the cultivated land scale in irrigation areas. |
