Abstract: As a principle index to measure water resources security, water resources carrying capacity relates with the problem of water resources security closely and becomes an emphases of water resources study which has important effection on the recognization and construction of water resources security system. Based on the definition of water resources carring capacity, this paper brings forward the theories about the study of water resources carrying capacity, concerning with the sustainable development, water resources-socialeconomy-environment coupling system and water cycle in duality mode. After a overall review of the contents and evaluation index system, the paper summarizes the evalauation methods of water resources carrying capacity study, including the imitate model with system dynamics theory, the decision model of multiple-purpose planning etc.. Finally, the paper points out that the further study of water resources carrying capacity should strengthen integration study of different subject, apply the new technology of GIS and RS actively and pay more attention to the study of region diversity.

Key words: evaluation methods, study direction, water resources carrying capacity
