Seagrasses, as globally distributed marine angiosperms, form seagrass beds which are among the most productive ecosystems and provide some of the highest value ecosystem services in the Earth's biosphere. However, with increasingly severe global climate change and frequent human disturbances, the decline of seagrass beds has already impacted the marine environment and biodiversity. This paper systematically reviews the current understanding of seagrass environmental adaptability. It clarifies the basic concept of seagrasses, their geographical distribution characteristics, morphological attributes, and the importance of their ecological functions. It provides a detailed analysis of seagrass adaptation strategies to common environmental stresses, primarily heat stress, and compares these with common terrestrial angiosperms. Subsequently, it elaborates on the current survival status of seagrasses and the main reasons for seagrass bed decline. Finally, based on the aforementioned research conclusions, it summarizes the core pattern of seagrass adaptation mechanisms. This paper aims to provide a theoretical reference for deepening research and conservation practices in seagrass-related fields, particularly for understanding how seagrasses utilize their own adaptation mechanisms to cope with environmental stresses induced by climate change and human disturbances.
