In China, irrigation plays a significant role in guaranteeing national food security. However, with the development of society and the economy, water resources have become increasingly short and the conflict between water supply and requirement is worsening in irrigation districts. How to optimize and allocate the limited water resources has become a research focus. Combining groundwater and surface water for agricultural irrigation is an effective approach to solve the problems. It is helpful to regulate and utilize the limited water resources more reasonably by conjunctive use of surface water and groundwater. It is also significant in protecting the environment and promoting sustainable development of irrigation districts. In this paper, the definition, principles and advantages of conjunctive use of surface and groundwater are introduced. Then related research is discussed from the perspectives of the research objectives, computing model and methodology. Study of the model on conjunctive use of surface and groundwater in irrigation districts is of great practical significance for the optimal allocation of water, the improvement of water resources utilization efficiency and the economic benefit of irrigated areas. © 2020 John Wiley & Sons, Ltd.
