Abstract: This paper briefly summarizes the development history of the impacts of climate change on wetland ecological water demand at home and abroad, and focuses on the key research areas of current climate change impacts on wetland ecological water demand. It includes the impact of climate change on the water demand of wetland plants, the impact of climate change on wetland soil water demand, the impact of climate change on wetland habitat water demand, the interaction and feedback mechanism of climate change and wetland ecological water demand, and future climate change scenarios, prediction of ecological water demand in wetlands and adaptive management strategies for wetland ecological water demand in climate change environments. In view of the problems and weak links in the current research, the suggestions and prospects for future research and the research directions that need to be focused on are proposed.
