Abstract: Mangrove ecosystems which distribute in intertidal zone have important ecological functions. Under the background of sea level rise, the survival of mangroves, especially endangered ones, is threatened by flooding stress. It is of great significance to understand the effects of flooding stress on mangroves. Flooding stress mainly affects the growth of mangroves, and further inhibits their physiology by affecting photosynthesis, stress-resistant enzyme activity, molecular regulation mechanisms, and root system. Although the effects of flooding stress on the physiological ecology of mangroves have been studied considerably, there are limitations in species identities and growth stages. Dynamic tidal simulation technology is the support of experimental design to study the physiological and ecological effects of flooding stress on mangroves. In the future, we should break through the bottleneck of dynamic tidal simulation technology and conduct more in-depth research combining ecosystem ecology, transcriptomics and metabolomics, to provide a basis for scientific understanding of mangroves’ response to global change and ecosystem management.
