Abstract: Wetlands provide enormous ecological services function for nature, which is an essential component for maintaining regional and national ecological security and promoting sustainable development. Digital twin technology provides a new method and tool for wetland research, which can achieve comprehensive digital virtualization of wetlands, real-time visualization of the entire process and collaborative intelligence of management decisions. It not only helps to understand the operational mechanism of wetland ecosystems, but also promotes the intelligent process of wetland research. In this paper, the characteristics of wetlands and digital twin technology are combined to study and analyze the construction of wetland digital twin systems from four aspects: wetland information monitoring layer, wetland information processing layer, wetland model analysis layer, and wetland application interaction layer, so as to achieve a highly integrated wetland digital twin system with informatization, digitalization and intelligence. Then, the key technologies of establishing a digital twin system for wetlands are introduced, including real-time monitoring technology, high performance data processing technology, complex wetland models, and visual interaction technology. In addition, the application of digital twin technology in wetland research was explored from five aspects: dynamic monitoring of wetland resources, wetland classification, wetland ecosystem assessment, wetland tourism, wetland planning and management. What's more, the current existing problems in the construction of wetland digital twin were discussed, including the fusion of multi-source data, complex wetland modeling and optimization, and visualization of wetland multiple scenes. It is expected that relevant work can provide reference for the further development and implementation of digital twin in wetland research.
