Research Progress on Species and Ecological Restoration Applications of Salt-tolerant Plants in Southern Coastal Regions

Salt-tolerant plants in the southern coastal areas in China were categorized based on their habitats and physiology. The geographic characteristics of the region were described for reference information. From the perspectives of pollution by heavy metals and organic compounds, salinization of sandy soil, decline of biodiversity, and eutrophication of water, the potentials of applying salt-tolerant plants in combination with other agents to reverse the deteriorating conditions and for ecological rejuvenation cited in literature were reviewed. This article covers the relevant basic studies, newly discovered and introduced salt-tolerant species, applicable materials and agents, and integrated systems incorporating varieties of plants for an effective land restoration. Challenges remaining beyond the ongoing progress are discussed with suggestions for future studies.
