Abstract: Water resource is an essential element for all lives on this planet, and it is faced with severe scarcity and pollution issues in many parts of the world. Regional water stress assessment becomes a critical part for water resources assessment and management. To better manage and govern water resources under water scarcity conditions, this study reviewed the main approaches for regional water resources stress assessment. The definition and connotation of water resources stress were analyzed, and the common used approaches for water stress assessment were divided into four categories including single indicator, supply-demand ratio, comprehensive assessment and water footprint assessment. Based on the previous studies, the basic theories, data requirements, calculation processes and applications of these approaches were analyzed. It is found that the supply-demand ratio method is the most objective and precise approach for water resources stress analysis. Besides, modified water footprint assessment is also a proper approach since it is simple in calculation and it considers ecological water requirements. Furthermore, this paper also discussed the promising focuses of future researches, including the integrated research of surface water and ground water and the consideration of the seasonal features of water resources.

Key words: regional water resources, water resources assessment, water resources scarcity, water resources stress
