Research progress on habitat connectivity in coastal waters: A review.

Ecological connectivity, as a research method related to spatial ecology and conservation biology, has attracted increasing attention from researchers at home and abroad in recent years. Habitat connectivity, as a key link in ecological connectivity, is of great significance to promote coastal ecological restoration and protection. However, there has been less systematic research about habitat connectivity due to lack of corresponding theories and practices. Therefore, this paper discusses habitat connectivity from three aspects: (1) the concept of habitat connectivity is introduced and clarified; (2) the application of connectivity in artificial habitat and adjacent waters and its relationship with biodiversity conservation are reviewed and illustrated with examples; and (3) the future development trends of this research direction are summarized and prospected in order to provide a scientific basis and useful reference for the related work of coastal restoration projects in China. Generally, this paper argues that an increase in human behaviour irreversibly destroys the connectivity between marine habitats and threatens the spatial and temporal scales of biodiversity and ecosystem services. Therefore, the theoretical research results and practical experience of ecological connectivity should be fully applied to marine ecosystems, and the restoration of degraded ecosystems should be encouraged and supported in ways that promote natural recovery.
